It is about what happens to the signal before it reaches your DAC — the quality of the clock, the cleanliness of the power, the isolation between the noisy digital processing and the audio output stage. The Matrix Audio NT-1 has been designed with those priorities in order. It is a transport first. Everything else — the storage, the app, the NAS integration — is built around that foundation rather than the other way around.\u003c\/p\u003e\n\u003cp\u003eMatrix Audio has been building serious digital hardware for long enough that their engineering decisions carry context. The NT-1 inherits the clock architecture from their flagship designs and applies it to a streaming transport at a price more people can reach.\u003c\/p\u003e\n\u003ch2\u003ePower Supply\u003c\/h2\u003e\n\u003cp\u003eThe NT-1 runs on a full linear power supply — a 60W toroidal transformer with multiple low-dropout regulators. The digital audio processing core and the USB DAC interface run from two independent transformer windings. That separation matters because the USB output is the path most sensitive to noise contamination from the digital side. Having the USB interface on its own isolated winding, with its own dedicated low-noise regulator circuit, means that what arrives at your DAC is as clean as Matrix can make it before the signal leaves the box. Switching power supplies introduce high-frequency noise that can be difficult to fully eliminate downstream. This design avoids the problem at the source.\u003c\/p\u003e\n\u003cp\u003eThe NVMe SSD — which sits in a dedicated slot on the underside of the unit — also gets its own ultra-low-noise independent power supply, isolated from the main digital section. In most computers and streamers, storage and audio processing share a power rail. Here they do not.\u003c\/p\u003e\n\u003ch2\u003eClock System\u003c\/h2\u003e\n\u003cp\u003eThe clock architecture is derived from Matrix Audio's flagship models. It operates in two modes. In internal clock mode, a femtosecond-grade oscillator feeds an RF synthesizer that outputs a highly stable, low-phase-noise audio clock. In external clock mode, an incoming reference signal becomes the input to the RF synthesizer, producing a clock that is both stable and phase-synchronized with the external reference. The external clock input is designed specifically for use with the Matrix SC-1 audio-grade clock source, and the combination represents a meaningful step beyond what the internal clock alone can provide. If you already own the SC-1 or are building a system around it, the NT-1 integrates cleanly.\u003c\/p\u003e\n\u003ch2\u003eUSB Output \u0026amp;  Isolation\u003c\/h2\u003e\n\u003cp\u003eThe USB DAC interface is electrically isolated — ground is separated from the device ground wire at the port. Transmission noise is reduced at the hardware level. Combined with the dedicated isolated power supply feeding this output, the NT-1's USB output is as considered as anything at this price point. If your DAC receives its input via USB, this is the detail that determines how much the transport contributes to or subtracts from the result.\u003c\/p\u003e\n\u003ch2\u003eOutputs \u0026amp; Connectivity\u003c\/h2\u003e\n\u003cp\u003eThe NT-1 covers the full range of digital output formats: optical, coaxial S\/PDIF, AES\/EBU balanced digital, IIS-LVDS, and the isolated USB DAC output. Active speakers with digital inputs can be driven directly, with the NT-1's digital volume control handling level — no separate preamp or controller required in that configuration. The SFP module slot allows the network connection to be expanded with an optical fibre or additional Ethernet port, and pairs with Matrix's own audio-grade network switch for a cleaner network environment.\u003c\/p\u003e\n\u003cp\u003eA 12V trigger output allows the NT-1 to wake connected equipment automatically — DAC, amplifier, or both — when playback begins. The unit also supports smart wake-up from network or local playback states without manual intervention.\u003c\/p\u003e\n\u003ch2\u003eStorage \u0026amp; Library Management\u003c\/h2\u003e\n\u003cp\u003eThe NVMe SSD slot handles local storage expansion. NAS drives can be mounted directly to the device for library access. Cloud storage — including Baidu Netdisk — mounts the same way. Dual USB 3.0 ports handle CD ripping via external drive and one-touch file copying. The device can serve as a NAS over SMB, making stored files accessible to computers on the network and to other streamers. If you have a large local library spread across multiple storage points, the NT-1 can function as the hub for all of it.\u003c\/p\u003e\n\u003ch2\u003eSoftware \u0026amp; Streaming\u003c\/h2\u003e\n\u003cp\u003eThe NT-1 is Roon Ready — certified, not just compatible. Roon delivers PCM up to 768kHz and DSD up to 11.29MHz natively through the NT-1. For those not running Roon, the MA Player OS handles TIDAL Connect, Qobuz Connect, Spotify Connect, AirPlay 2, DLNA\/UPnP, vTuner, and Radio Paradise. Local file playback covers every format worth mentioning: FLAC, WAV, AIFF, DSD (DSF and DFF), ALAC, APE, CUE, and ISO, up to PCM 768kHz and DSD 24.58MHz.\u003c\/p\u003e\n\u003cp\u003eControl is via the MA Remote app for iOS and Android. Matrix updates the MA Player OS continuously — streaming service support and interface refinements arrive over time, so the platform you buy is not the ceiling. Worth checking the current firmware release notes if specific service support matters to your setup.\u003c\/p\u003e\n\u003ch2\u003eWhere It Fits\u003c\/h2\u003e\n\u003cp\u003eThe NT-1 is a transport, not a DAC. It needs something downstream — a DAC you believe in, connected by the output type that suits your setup. The isolated USB output is the starting point for most systems at this level, though the AES\/EBU and IIS-LVDS outputs are there for those whose DACs prefer them. If your DAC accepts an external clock, the SC-1 pairing extends the system considerably. If you are streaming high-resolution local files or Qobuz and Tidal-level services into a serious DAC, the NT-1 is the correct problem to solve before spending more money on the DAC itself.\u003c\/p\u003e\n\u003ch2\u003ePress Recognition\u003c\/h2\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cbr\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/RrxfnN5O0JU?si=TpR90tAjGrqJFccI\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e \u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/h-oPnldTHdY?si=L1WbFyjEk1rofR11\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Network audio transport \/ streamer\u003c\/li\u003e\n\u003cli\u003eClock: Dual-mode femtosecond clock system with RF synthesizer; external 10MHz clock input (50Ω, sine or square wave)\u003c\/li\u003e\n\u003cli\u003ePower supply: 60W toroidal transformer, multiple LDOs, independent windings for audio processing core and USB DAC output\u003c\/li\u003e\n\u003cli\u003eCoaxial \/ Optical \/ AES\/EBU output: PCM 16–24 bit \/ 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz; DSD 2.8MHz (DoP)\u003c\/li\u003e\n\u003cli\u003eIIS-LVDS output: PCM 16–32 bit \/ 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz, 352.8kHz, 384kHz, 705.6kHz, 768kHz; DSD 2.82MHz, 3.07MHz, 5.64MHz, 6.14MHz, 11.29MHz, 12.29MHz, 22.58MHz, 24.58MHz\u003c\/li\u003e\n\u003cli\u003eUSB DAC output: Up to PCM 32 bit \/ 768kHz and DSD 24.58MHz (dependent on connected DAC); electrically isolated; dedicated 5V\/1A low-noise power supply\u003c\/li\u003e\n\u003cli\u003eNetwork: LAN 10\/100\/1000 Mbps; SFP module slot 10\/100\/1000 Mbps (optical fibre or additional Ethernet)\u003c\/li\u003e\n\u003cli\u003eUSB: 2 x USB 3.0 (5V\/1A each); FAT, FAT32, exFAT, NTFS support\u003c\/li\u003e\n\u003cli\u003eStorage expansion: M.2 2280\/2260\/2242 NVMe PCIe SSD slot (3.3V\/3A max)\u003c\/li\u003e\n\u003cli\u003eLocal playback formats: MP3, WMA, WAV, AIF, AIFC, AIFF, AAC, FLAC, OGG, APE, ALAC, M4A, DSF, DFF, CUE, ISO\u003c\/li\u003e\n\u003cli\u003eLocal playback resolution: PCM 16–24 bit up to 768kHz; DSD up to 24.58MHz\u003c\/li\u003e\n\u003cli\u003eRoon Ready: Yes — PCM 16–24 bit up to 768kHz; DSD 2.82MHz, 5.64MHz, 11.29MHz, 22.58MHz\u003c\/li\u003e\n\u003cli\u003eStreaming services: TIDAL Connect, Qobuz Connect, Spotify Connect, AirPlay 2, DLNA\/UPnP, vTuner, Radio Paradise, QQ Music\u003c\/li\u003e\n\u003cli\u003eNAS support: Yes — NAS mounting; SMB sharing and NAS serving to other devices on network\u003c\/li\u003e\n\u003cli\u003eCD ripping: Yes, via external USB CD drive; auto-rip with one-touch copy\u003c\/li\u003e\n\u003cli\u003eTrigger input: DC 6–12V, under 10mA\u003c\/li\u003e\n\u003cli\u003eTrigger output: DC 12V \/ 50mA\u003c\/li\u003e\n\u003cli\u003eControl: MA Player OS; MA Remote app (iOS and Android)\u003c\/li\u003e\n\u003cli\u003ePower consumption: Under 5W standby \/ under 50W maximum\u003c\/li\u003e\n\u003cli\u003eAC input: 100–120V or 220–240V, 50\/60Hz, auto-ranging\u003c\/li\u003e\n\u003cli\u003eDimensions: 330mm W x 267mm D x 97mm H\u003c\/li\u003e\n\u003cli\u003eWeight: 4.6kg\u003c\/li\u003e\n\u003cli\u003eManufactured: China\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eIf you are building a streaming front end and want to think through transport, DAC, and clock pairing before committing — what works together, what the upgrade path looks like — we are happy to work through it.

Matrix Audio could have built a feature-rich converter with streaming built in, a headphone stage, a preamp section, and a list of functions long enough to justify the price on weight alone. They didn't. The ND-1 does one thing — digital to analogue conversion — and it is built around the question of how to do that as well as possible at its price point. Everything else was left out deliberately.\u003c\/p\u003e\n\u003cp\u003eThe result is a DAC that sits at the centre of the Matrix N Series alongside the NT-1 transport and NA-1 headphone amplifier, designed to be paired rather than to contain everything. If you are building a separates system, this is the converter the system is built around.\u003c\/p\u003e\n\u003ch2\u003eThe Chip Architecture\u003c\/h2\u003e\n\u003cp\u003eMatrix chose AKM's current flagship combination: the AK4191EQ delta-sigma modulator paired with two AK4499EX DAC chips. The 1+2 arrangement means the AK4191EQ handles all the high-precision digital processing and reclocking upstream, then hands off to one AK4499EX per channel. Each converter chip is dedicated entirely to one channel — left or right — rather than sharing a single chip across both. The practical benefits are better channel separation and more consistent phase performance between channels. The SNR and dynamic range figures that result are at the top of what delta-sigma conversion currently achieves.\u003c\/p\u003e\n\u003cp\u003eThe AK4499EX is not a new chip, but it remains the reference point for high-performance delta-sigma conversion. What matters more than the chip selection is what surrounds it — clock quality, power supply integrity, and output stage design. Matrix has put serious attention into all three.\u003c\/p\u003e\n\u003ch2\u003eClock \u0026amp; Jitter\u003c\/h2\u003e\n\u003cp\u003eThe ND-1 uses a custom-built ultra-low phase noise femtosecond clock as the D\/A conversion reference. The DPLL clock synthesis circuit — derived from Matrix's flagship MS-1 — also supports an external 10MHz clock input, which accepts either sine or square wave reference signals. The pairing with the Matrix SC-1 clock source is the obvious path for those who want to take the clock section further. It is not a requirement. The internal clock is genuinely good. The external clock input is there because Matrix knows some of their customers will want to go further.\u003c\/p\u003e\n\u003cp\u003eElectrical isolation on all digital inputs is worth noting here too — optical, coaxial, AES\/EBU, IIS-LVDS, and both USB ports all have isolation between the source device and the DAC circuitry. Ground loop noise and common-mode interference are blocked before they reach the conversion stage.\u003c\/p\u003e\n\u003ch2\u003eThe Output Stage — Why It Matters\u003c\/h2\u003e\n\u003cp\u003eThis is where the ND-1 does something genuinely unusual. The output stage is switchable between two configurations: Lundahl precision transformer coupling and conventional op-amp output. Both modes use the same XLR and RCA outputs. The switch changes the character of what comes out of them.\u003c\/p\u003e\n\u003cp\u003eIn transformer mode, the signal passes through Lundahl audio transformers in the output coupling — a Swedish manufacturer known for precision magnetics used in professional and high-end audio equipment. The result is a warmer presentation, with the density and harmonic richness that transformer coupling tends to produce. Some people hear this as more analogue-like. That description is not wrong, though it is incomplete.\u003c\/p\u003e\n\u003cp\u003eIn op-amp mode, the output stage is faster and more linear — sharper transient definition, cleaner delineation between sounds, higher measured resolution. The THD+N in op-amp mode is 0.0002% at 1kHz versus 0.02% in transformer mode. The transformer mode trades some measured performance for a different tonal character. Whether that trade is worth making depends entirely on what you want the system to sound like.\u003c\/p\u003e\n\u003cp\u003eThe point is that you have the choice, in the same box, without needing a second DAC to hear what the difference actually sounds like in your system.\u003c\/p\u003e\n\u003ch2\u003eOutput Levels \u0026amp; Volume Control\u003c\/h2\u003e\n\u003cp\u003eBoth XLR and RCA outputs offer two selectable fixed output levels alongside a 100-step digital volume attenuation. XLR runs at 4.5Vrms; RCA at 2.25Vrms. The level selection allows the ND-1 to be matched to the input sensitivity of what follows it — amplifier, active speakers, or the NA-1 headphone amplifier — without introducing gain staging problems. The 100-step volume control means the ND-1 can drive a power amplifier or active speakers directly, removing the preamp from the chain entirely if that is the preferred configuration.\u003c\/p\u003e\n\u003ch2\u003eUpsampling \u0026amp; DSD Conversion\u003c\/h2\u003e\n\u003cp\u003eThe ND-1 has a built-in asynchronous upsampling and DSD conversion engine. In upsampling mode, all PCM is resampled before conversion — the asynchronous process isolates jitter from the source and can improve perceived detail. In DSD conversion mode, all incoming audio is converted to DSD before the DAC stage, which some listeners prefer for its effect on density and tonal weight. Both modes are configurable, and the processing engine supports different PCM and DSD conversion options. Whether or not to engage these is a matter of preference and experimentation. The option is there; it is not imposed.\u003c\/p\u003e\n\u003ch2\u003ePower Supply \u0026amp; Construction\u003c\/h2\u003e\n\u003cp\u003eThe ND-1 uses a multi-winding toroidal transformer with multiple LDOs — a full linear supply throughout, with the digital and analogue sections on separate PCBs and separate windings. Digital circuitry sits on the lower board; the D\/A conversion stage is on the upper board above it. The separation reduces interference from the digital section reaching the analogue output stage. This kind of physical and electrical separation between digital and analogue is standard at the price points above the ND-1. Matrix has implemented it here.\u003c\/p\u003e\n\u003cp\u003eThe chassis is CNC-machined aluminium. The ND-1 also ships with Matrix's MA-DAMPER PRO isolation feet, developed with Audio Bastion, using five materials — aluminium, stainless steel, rubber, isolation beads, and composite cork — in a multi-layer vibration control system.\u003c\/p\u003e\n\u003ch2\u003eWhere It Fits\u003c\/h2\u003e\n\u003cp\u003eThe ND-1 is built to sit downstream of the NT-1 transport and upstream of the NA-1 headphone amplifier or a separate power amplifier. All three units share the same 330mm width and 97mm height — they stack or rack as a coherent system. The IIS-LVDS input is the optimal connection from the NT-1 if your setup supports it, reaching 32-bit \/ 768kHz PCM and DSD up to 49.15MHz native — the highest resolution available between the two units. The external clock input ties into the SC-1 if you are building the full system.\u003c\/p\u003e\n\u003cp\u003eIt also works independently of the Matrix ecosystem. Any transport or computer audio source feeding it via USB or S\/PDIF will benefit from the chip architecture, the clock quality, and the isolation design. The Lundahl transformer option is a differentiator regardless of what is upstream.\u003c\/p\u003e\n\u003ch2\u003ePress Recognition\u003c\/h2\u003e\n\u003cp\u003eThe ND-1 is a recent release and formal press coverage is still building at the time of writing. We will update this page as substantive reviews are published. Matrix Audio's N Series as a system has attracted attention since launch, and the ND-1 sits at its centre.

If you want to understand why the NT-1 and ND-1 are built the way they are, the MS-1 is the explanation.\u003c\/p\u003e\n\u003cp\u003eIt is a music streamer, a DAC, and a preamplifier in a single chassis — the kind of integrated source component that either simplifies a system or concentrates everything you care about in one box, depending on how you look at it. At 14.6kg and with dual heavy-duty toroidal transformers inside, it is built to the standard of separates that cost considerably more individually.\u003c\/p\u003e\n\u003ch2\u003eThe chipset and channel architecture\u003c\/h2\u003e\n\u003cp\u003eThe MS-1 uses AKM's flagship combination: dual AK4191 modulators paired with dual AK4499 DAC chips, each set running in mono mode for one channel. Left and right channel PCB assemblies are mounted on opposite sides of the H-shaped chassis, completely separated. This is a genuine dual-mono implementation — not a single chip with left and right channels sharing a substrate, but two independent conversion paths from modulator through DAC to output. Channel separation and phase consistency reflect that. The SNR on the fixed XLR line output is 131dB A-weighted. THD+N at 1kHz is 0.000068%. These are exceptional measurements, but the measurements are a consequence of the architecture rather than the goal of it.\u003c\/p\u003e\n\u003ch2\u003ePower supply\u003c\/h2\u003e\n\u003cp\u003eTwo toroidal transformers — one for the digital section, one for the analogue — wound with square-section copper wire rather than the conventional round wire. The larger conductor surface area of square wire gives lower resistance, higher current capacity, and better transient response. Matrix pairs these with Mundorf M-Lytic AG series filter capacitors, which add a specific tonal character to the supply rail that their engineers preferred to standard alternatives. Dozens of low-dropout regulators follow, including ultra-low-noise LDOs on the most sensitive circuit nodes. The NVMe SSD, if fitted, gets its own regulated supply from this same system.\u003c\/p\u003e\n\u003cp\u003eThis level of power supply engineering is what separates a product like the MS-1 from equipment that achieves similar measurements through chip selection alone. The power supply determines the ceiling. Everything else approaches it.\u003c\/p\u003e\n\u003ch2\u003eThe volume control\u003c\/h2\u003e\n\u003cp\u003eThe MS-1 Pre uses a precision resistor array volume control — 64 resistors at 1‰ accuracy, switched by 32 sealed reed relays under MCU control. Reed relays are fast, reliable, and introduce negligible contact resistance. The switching arrangement achieves near-perfect channel tracking across the volume range without the channel imbalance at low levels that affects many attenuator designs. The relay switching noise, Matrix notes, is almost inaudible even when changing volume continuously. The pre output reaches 16Vrms on XLR — enough to drive any power amplifier directly, with substantial headroom to spare.\u003c\/p\u003e\n\u003ch2\u003eClock\u003c\/h2\u003e\n\u003cp\u003eThe DPLL clock synthesis circuit in the MS-1 is the reference design that the NT-1 and ND-1 derive from. An ultra-low phase noise oscillator feeds the DPLL circuit, producing a clock with jitter as low as 45 femtoseconds. An external 10MHz clock input — 50Ω, sine or square wave — allows connection to a reference clock source such as the Matrix SC-1. The internal clock is already exceptional. The external input is for those who want to push further.\u003c\/p\u003e\n\u003ch2\u003eAnalog inputs and phono stage\u003c\/h2\u003e\n\u003cp\u003eThis is where the MS-1 goes beyond what a conventional streamer-DAC does. Two pairs of analogue line inputs — XLR and RCA — plus a phono input with both MM and MC modes. All analogue inputs are converted to digital via high-precision ADC and processed through the digital engine, which means they benefit from the same PCM filtering and upsampling options as the digital inputs. They can also be output via the IIS-LVDS port for connection to an external DAC.\u003c\/p\u003e\n\u003cp\u003eThe phono stage: MM mode at +45dB gain into 47kΩ \/ 100pF; MC mode at +65dB gain into 100Ω. Both RIAA equalised. This is not an afterthought. Having a genuinely capable MC phono stage in the same chassis as a reference-level DAC and preamp is the kind of integration that simplifies a system without compromising any part of it.\u003c\/p\u003e\n\u003ch2\u003eInputs and outputs — the full picture\u003c\/h2\u003e\n\u003cp\u003eDigital inputs cover optical, coaxial, IIS-LVDS, and USB audio — the IIS-LVDS input reaches PCM 768kHz and DSD 49.15MHz native, the highest resolution available across the Matrix ecosystem. The IIS-LVDS digital output passes the same resolution out to an external DAC. All analogue inputs — line and phono — can also exit via IIS-LVDS, which means the MS-1 can function as an ADC front end for an external conversion chain.\u003c\/p\u003e\n\u003cp\u003eThe fixed XLR line output at 5Vrms provides a constant-level feed for recording or monitoring equipment alongside the variable pre output. Both can be active simultaneously.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0572\/0522\/7587\/files\/MS-1_i2s_inputs.png?v=1780360362\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0572\/0522\/7587\/files\/MS-1_Analog_Inputs.png?v=1780360386\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003eThe Chassis\u003c\/h2\u003e\n\u003cp\u003eThe H-shaped chassis is a Matrix Audio original — a 20mm CNC-machined aluminium plate forms the main structural beam, with all components mounted to it. The panel installation creates separate isolated cavities for different circuit modules. Left and right channel modules sit symmetrically on either side of the central structure. It is 430mm wide, 353mm deep, 106mm tall, and 14.6kg. It is substantially larger and heavier than the NT-1 and ND-1, which share the same 330mm-wide family format — the MS-1 is a different class of product physically as well as technically.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0572\/0522\/7587\/files\/MatrixAudioMS-1chassis.png?v=1780359803\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003eStreaming \u0026amp; Software\u003c\/h2\u003e\n\u003cp\u003eThe MS-1 is Roon Ready.

The MA Remote App handles all control — playback, volume, filter selection, display settings, hardware configuration — from iOS or Android.

It drives a power amplifier directly from its XLR pre output at up to 16Vrms. It feeds a separate DAC via IIS-LVDS if you want to use external conversion. It is a hub as much as a component, and it is designed to be the fixed centre of a system that may grow around it.\u003c\/p\u003e\n\u003cp\u003eCompared to the NT-1 and ND-1 in combination, the MS-1 offers the phono stage, the resistor array volume control, the higher-current power supply, and the dual-mono architecture in a single chassis. The N Series separates path gives you more flexibility in component choice and the ability to upgrade DAC and transport independently. Neither approach is wrong. It depends on how you build systems.\u003c\/p\u003e\n\u003ch2\u003ePress Recognition\u003c\/h2\u003e\n\u003cp\u003eFormal press coverage of the MS-1 is still developing at time of writing.

It is a streamer and DAC in one chassis, intended for those who want a single high-quality source component rather than a separate transport and converter. It does not include the MS-1's analogue inputs, phono stage, or preamp output. What it does include is the flagship AKM chipset, Lundahl transformer coupling in the output stage, and dual femtosecond clocks.\u003c\/p\u003e\n\u003cp\u003eFor someone building from a source rather than around existing components, the MS-1c is a very complete starting point.\u003c\/p\u003e\n\u003ch2\u003eThe DAC \u0026amp; Clock Architecture\u003c\/h2\u003e\n\u003cp\u003eThe MS-1c uses AKM's AK4191 modulator paired with the AK4499EX DAC chip — the VELVETSOUND flagship combination, the same chipset at the heart of the ND-1. Dynamic range is rated at 125dB, SNR on the XLR output at 126dB A-weighted. These are strong numbers for an integrated device at this level.\u003c\/p\u003e\n\u003cp\u003eThe clock architecture is a notable upgrade over the NT-1's single femtosecond oscillator. The MS-1c uses two custom femtosecond clocks — one as the reference for 44.1kHz-based sample rates, one for 48kHz-based rates. A high-speed FPGA handles frequency division and jitter reduction between the clocks and the conversion circuit. The two-clock approach eliminates the sample rate conversion artefacts that a single-clock system introduces when switching between 44.1kHz and 48kHz families, and it produces lower phase noise at each rate. The practical effect is better perceived detail and what Matrix describe as improved airiness and texture — descriptions that are imprecise but point at something real in the time domain performance.\u003c\/p\u003e\n\u003ch2\u003eLundahl Transformer Output\u003c\/h2\u003e\n\u003cp\u003eLike the ND-1, the MS-1c uses Swedish Lundahl precision transformers for signal coupling in the analogue output stage. The transformer character — warmer, smoother, with the harmonic density that transformer coupling tends to produce — is baked into the output stage here rather than being a switchable option as it is in the ND-1. THD+N is 0.02% at 1kHz on both XLR and RCA outputs, which reflects the transformer's tonal signature rather than a limitation of the conversion. If you know you prefer the transformer sound, the MS-1c gives you it without the op-amp alternative. If you want to choose between them, the ND-1 is the right product.\u003c\/p\u003e\n\u003cp\u003eXLR output is 4.5Vrms with 100-step digital volume attenuation. RCA is 2.25Vrms, same control. Both outputs can drive a power amplifier or active speakers directly, removing the need for a separate preamp in that configuration.\u003c\/p\u003e\n\u003ch2\u003eDigital Outputs \u0026amp; Transport Capability\u003c\/h2\u003e\n\u003cp\u003eThe MS-1c is not just a streamer-DAC — it can also function as a high-quality transport feeding an external DAC. Optical, coaxial, and AES\/EBU outputs cover the standard S\/PDIF formats; IIS-LVDS reaches PCM 768kHz and DSD 24.58MHz for DACs that support it. The USB DAC output, with its 5V\/1A low-noise dedicated supply, handles whatever the connected DAC can accept up to PCM 768kHz and DSD 24.58MHz. That output capability makes the MS-1c a credible upgrade path — it will work with a better external DAC if and when that becomes the priority, without requiring a transport change.\u003c\/p\u003e\n\u003ch2\u003eNetworking\u003c\/h2\u003e\n\u003cp\u003eThe MS-1c adds Wi-Fi 6 to the connectivity options — the MS-1 and NT-1 are wired-only. Gigabit Ethernet remains the preferred connection for high-resolution PCM and DSD playback, but Wi-Fi 6 is a genuine option for systems where running a cable to the rack is not practical. The SFP slot of the MS-1 and NT-1 is not present on the MS-1c.\u003c\/p\u003e\n\u003ch2\u003eStreaming \u0026amp; Software\u003c\/h2\u003e\n\u003cp\u003eThe MS-1c is Roon Ready and also supports Audirvāna and NAA — the latter two are notable additions not present on the NT-1. Apple Music is natively integrated alongside TIDAL Connect, Qobuz Connect, Spotify Connect, AirPlay 2, DLNA\/UPnP, HIGHRESAUDIO, vTuner, and Radio Paradise. Dropbox can be mounted as a music source alongside NAS and internal SSD. The MA Remote App handles all control from iOS, iPadOS, and Android.\u003c\/p\u003e\n\u003cp\u003eCD ripping and playback is supported via external USB CD drive — the same one-touch rip-to-storage workflow as the NT-1.\u003c\/p\u003e\n\u003ch2\u003ePower Supply \u0026amp; Construction\u003c\/h2\u003e\n\u003cp\u003eThe power supply separates digital and analogue sections with independent supplies. The analogue stage runs from a dedicated linear supply with multiple LDO regulators. This is a less elaborate arrangement than the dual square-copper-wire transformers and Mundorf capacitors of the MS-1, which reflects the price difference — but the separation principle and the linear regulation for the analogue output stage are the same approach. The NVMe SSD slot on the underside has its own ultra-low-noise independent supply, the same design as the NT-1.\u003c\/p\u003e\n\u003cp\u003eIsolation is handled by the MA-DAMPER STD — the standard version of the Audio Bastion-developed damper system, using silicone damping internally. The MS-1 uses the more elaborate MA-DAMPER PRO five-material system. The chassis is CNC-machined aluminium, 430mm wide at the same footprint as the MS-1, 315mm deep rather than 353mm, and 6.5kg — considerably lighter than the MS-1's 14.6kg, which reflects the simpler power supply topology.\u003c\/p\u003e\n\u003ch2\u003eWhere It Fits\u003c\/h2\u003e\n\u003cp\u003eThe MS-1c occupies the space between the NT-1 transport and the MS-1 integrated flagship. Against the NT-1 it adds a built-in DAC with Lundahl output, analogue outputs, Wi-Fi 6, Apple Music, Audirvāna and NAA support, and the dual-clock architecture. Against the MS-1 it gives up the phono stage, analogue inputs, the reed relay volume control, the heavier power supply, the SFP port, and the dual-mono chipset layout.\u003c\/p\u003e\n\u003cp\u003eIf you are streaming — digital sources only, no vinyl — and want a single component that handles conversion as well as transport, the MS-1c makes that case cleanly. If vinyl or analogue inputs matter, the MS-1 is the only Matrix product that covers them. If you want the best separate transport and the freedom to change the DAC independently, the NT-1 is the right path.\u003c\/p\u003e\n\u003ch2\u003ePress Recognition\u003c\/h2\u003e\n\u003cp\u003eThe MS-1c is a recent release.

The short version: every digital audio device — streamer, DAC, CD transport — runs on a clock. The quality of that clock determines how accurately the device can reconstruct audio timing. Jitter, which is variation in the clock signal's timing, is directly audible as smearing of fine detail and spatial information. A better clock produces lower jitter. The SC-1 is a purpose-built 10MHz reference clock that connects to compatible equipment and replaces their internal clock reference with something considerably more precise.\u003c\/p\u003e\n\u003cp\u003eThis is Matrix Audio's first clock source product. They built it as the natural completion of the N Series and M Series ecosystem — the SC-1 is what the clock inputs on the NT-1, ND-1, MS-1, and MS-1c are waiting for.\u003c\/p\u003e\n\u003ch2\u003eThe oscillator\u003c\/h2\u003e\n\u003cp\u003eAt the centre of the SC-1 is a custom OCXO — an oven-controlled crystal oscillator. The crystal uses an SC cut, a more complex and expensive cutting geometry than the standard AT cut used in most oscillators. The SC cut offers lower phase noise and better aging characteristics — the frequency drifts less over time as the crystal ages. The oven chamber maintains the crystal at a precise operating temperature, which eliminates the frequency variation caused by ambient temperature fluctuations. Warm-up time to rated specification is under five minutes at 25°C.\u003c\/p\u003e\n\u003cp\u003eFrequency accuracy when shipped is better than ±0.01ppm. Temperature stability across the full -40°C to +70°C range is better than 0.003ppm. Short-term stability is better than 5×10⁻¹³ at tau equals one second. These are numbers that are difficult to contextualise without comparison, but the short version is that the SC-1's oscillator is operating at a level of precision that exceeds what any consumer audio device's internal clock is likely to achieve.\u003c\/p\u003e\n\u003ch2\u003ePhase noise and jitter\u003c\/h2\u003e\n\u003cp\u003ePhase noise is the relevant measure for audio clock quality. The SC-1 achieves better than -118dBc\/Hz at 1Hz offset from the carrier, measured at the output port — not at the oscillator itself, which is an important distinction. The output buffering circuit always degrades the signal somewhat; Matrix have designed the buffer stage well enough that the output measurement remains better than -118dBc\/Hz at 1Hz, dropping to -140dBc\/Hz at 10Hz, -150dBc\/Hz at 100Hz, -160dBc\/Hz at 1kHz, and a noise floor better than -170dBc\/Hz.\u003c\/p\u003e\n\u003cp\u003eJitter at the output is 20 femtoseconds, measured over 1–100Hz. For reference, the NT-1's internal femtosecond clock system — which is already exceptional — produces a clock the SC-1 can improve upon. That improvement is what Matrix's own measurements of the NT-1 and MS-1c in external clock mode are designed to demonstrate.\u003c\/p\u003e\n\u003ch2\u003eFour independent outputs\u003c\/h2\u003e\n\u003cp\u003eThe SC-1 has four BNC outputs, each with its own independent buffer circuit. They all derive from the same oscillator source, so they are phase-synchronised. The independent buffers mean each output has stable 50Ω impedance and sufficient drive capability regardless of whether one output or all four are in use simultaneously. This matters for anyone building a system with multiple components that accept a reference clock — a transport and a DAC, for instance, or a full N Series stack with NT-1, ND-1, and a future addition.\u003c\/p\u003e\n\u003cp\u003eOutput waveform — sine or square wave — is fixed at the factory to customer specification at the time of order. Square wave is recommended by Matrix for higher locking accuracy. Sine wave output is 0.5Vrms; square wave is 1Vrms. Both at 50Ω output impedance.\u003c\/p\u003e\n\u003ch2\u003eCalibration and long-term accuracy\u003c\/h2\u003e\n\u003cp\u003eEven an SC-cut OCXO drifts slightly over time. The SC-1 includes a 1PPS reference signal input on the rear panel for connection to an external seconds-based reference — GPS disciplined oscillators are the common source for this. When a 1PPS reference is connected, the SC-1 calibrates automatically, with calibration status shown on the front panel LED. Matrix also offers free factory calibration service for the SC-1 as a longer-term maintenance option.\u003c\/p\u003e\n\u003ch2\u003ePower supply\u003c\/h2\u003e\n\u003cp\u003eThe SC-1 runs on a linear power supply with automatic voltage detection and switching — it adapts to 100–120V and 220–240V without manual configuration. The supply uses dual multi-stage regulators, with the oven control circuit and the clock circuit on separate independent regulated rails. The reason for the separation is specific: the oven control circuit draws variable current as it maintains temperature, and that variation would introduce noise into the clock circuit if they shared a regulator. Keeping them independent eliminates that interference path. Maximum power consumption is under 20W.\u003c\/p\u003e\n\u003ch2\u003eWhere it fits\u003c\/h2\u003e\n\u003cp\u003eThe SC-1 connects via BNC to the 10MHz clock input on any compatible Matrix Audio product — NT-1, ND-1, MS-1, or MS-1c. Non-Matrix equipment with a 10MHz reference input will also work, provided the input accepts the SC-1's signal level and impedance. The same 330mm width and 97mm height as the NT-1 and ND-1 means the SC-1 stacks cleanly in an N Series system.\u003c\/p\u003e\n\u003cp\u003eWhether the SC-1 is worth adding depends on how far you have taken the rest of the system. If you are running a NT-1 into a ND-1 with good cabling and a capable amplifier, the SC-1 is the next logical step. It is not the first upgrade to make — the transport, the DAC, the power amplifier, and the speakers will each have more impact individually. But in a system that is already well sorted, the SC-1 addresses the last remaining variable in the digital chain.\u003c\/p\u003e\n\u003ch2\u003ePress recognition\u003c\/h2\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/MwIXFEMhUus?si=bSGhB4wNyVDFHn2l\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e \u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: 10MHz reference clock source\u003c\/li\u003e\n\u003cli\u003eOscillator: Custom OCXO, SC-cut crystal\u003c\/li\u003e\n\u003cli\u003eOutput frequency: 10.000MHz\u003c\/li\u003e\n\u003cli\u003eFrequency accuracy (shipped): \u0026lt;±0.01ppm\u003c\/li\u003e\n\u003cli\u003eFrequency stability vs temperature (-40°C to +70°C): \u0026lt;0.003ppm\u003c\/li\u003e\n\u003cli\u003eShort-term stability: \u0026lt;5×10⁻¹³ @ tau = 1s\u003c\/li\u003e\n\u003cli\u003eWarm-up time: Under 5 minutes @ 25°C\u003c\/li\u003e\n\u003cli\u003ePhase noise @ 1Hz offset: ≤-118dBc\/Hz\u003c\/li\u003e\n\u003cli\u003ePhase noise @ 10Hz offset: ≤-140dBc\/Hz\u003c\/li\u003e\n\u003cli\u003ePhase noise @ 100Hz offset: ≤-150dBc\/Hz\u003c\/li\u003e\n\u003cli\u003ePhase noise @ 1kHz offset: ≤-160dBc\/Hz\u003c\/li\u003e\n\u003cli\u003eNoise floor: ≤-170dBc\/Hz\u003c\/li\u003e\n\u003cli\u003eJitter: 20fs (measured 1–100Hz at output port)\u003c\/li\u003e\n\u003cli\u003eOutput ports: 4 x BNC, independent buffer circuits\u003c\/li\u003e\n\u003cli\u003eOutput impedance: 50Ω\u003c\/li\u003e\n\u003cli\u003eOutput level: 0.5Vrms (sine wave) \/ 1Vrms (square wave)\u003c\/li\u003e\n\u003cli\u003eOutput waveform: Sine or square wave (factory configured to order)\u003c\/li\u003e\n\u003cli\u003eReference input: 1PPS for external calibration\u003c\/li\u003e\n\u003cli\u003ePower supply: Dual-regulated linear supply, auto-ranging (100–120V \/ 220–240V, 50\/60Hz)\u003c\/li\u003e\n\u003cli\u003ePower consumption: Under 20W maximum\u003c\/li\u003e\n\u003cli\u003eIsolation: CBVB vibration-absorbing foot pads\u003c\/li\u003e\n\u003cli\u003eDimensions: 330mm W x 267mm D x 97mm H\u003c\/li\u003e\n\u003cli\u003eWeight: 4.4kg\u003c\/li\u003e\n\u003cli\u003eManufactured: China\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eIf you are weighing whether the SC-1 makes sense as the next step for your Matrix system — or trying to work out what order to build the chain in — we are happy to talk through it.

The Ethernet cable connecting your streamer to your router or switch carries data, but it also carries common-mode interference — electromagnetic noise generated by switching power supplies, ground potential differences between devices, and the high-frequency hash that modern network infrastructure radiates. None of this belongs in a signal path. The SI-1 is Matrix Audio's answer to that problem: an active optical-electrical isolator that sits between your network switch and your streamer and removes the electrical connection between them entirely.\u003c\/p\u003e\n\u003cp\u003eIt is a small box. What happens inside it is not simple.\u003c\/p\u003e\n\u003ch2\u003eHow it works\u003c\/h2\u003e\n\u003cp\u003eThe SI-1 uses a dual-channel optical transmission architecture — separate optical paths for transmit and receive. The incoming Ethernet signal is converted to optical, transmitted across an electrically isolated gap, and converted back to electrical at the output. No electrons pass between the input and output ports. Ground loops cannot form. Common-mode noise from the upstream network has no path to the downstream audio equipment.\u003c\/p\u003e\n\u003cp\u003eThe output port also incorporates a physical electrical isolation washer at the RJ45 connector, adding a further layer of separation. The result is that the SI-1 does not merely attenuate noise — it breaks the electrical continuity between the network infrastructure and the audio component completely. Lightning, power surges, and electrostatic discharge from the network side cannot reach the streamer or DAC on the other side.\u003c\/p\u003e\n\u003ch2\u003eClocks and power supply\u003c\/h2\u003e\n\u003cp\u003eOptical isolation introduces a reclocking requirement — the signal has to be regenerated on the output side, and the quality of that regeneration depends on the clock used. The SI-1 uses two femtosecond clocks, one for each transmission direction. A linear power supply built around a dual-winding potted toroidal transformer and multiple LDOs powers the device, with the dual windings providing independent supply rails for the two clock and transmission circuits. The approach is consistent with what Matrix has applied across the N Series and M Series — linear power, multiple LDOs, and the best available clock hardware for the task. In a network isolator, this is not common.\u003c\/p\u003e\n\u003ch2\u003eWhat it does to the sound\u003c\/h2\u003e\n\u003cp\u003eThe effect of effective network isolation is a lower noise floor — what is often described as a blacker background. With less noise corrupting the signal arriving at the streamer's input, fine detail that was previously masked becomes audible. Spatial information improves. The improvement is more obvious in some systems than others, typically more significant where the network infrastructure is noisier or where the rest of the system is already well resolved. In a system built around the NT-1, MS-1, or MS-1c, the SI-1 is the upstream problem the rest of the chain cannot solve on its own.\u003c\/p\u003e\n\u003ch2\u003ePractical details\u003c\/h2\u003e\n\u003cp\u003eTwo 1Gbps RJ45 ports — one input from the network switch or router, one isolated output to the audio component. Full gigabit throughput is maintained; there is no bandwidth penalty for the isolation. The LED indicators on the rear Ethernet ports can be switched off, which Matrix includes for a specific reason: in a darkened listening room, activity LEDs blinking in your peripheral vision are a distraction. The front panel LEDs show power and link status clearly when needed and can be left on without issue.\u003c\/p\u003e\n\u003cp\u003eThe enclosure is CNC-machined aluminium in unibody construction — the same design language as the rest of the Matrix N and M Series.

If you are building a serious system for a second room, a home office, or a living space where a stack of separates is impractical — or if you want a genuinely capable all-in-one that does not compromise where it matters — the MD-1P deserves a careful look.\u003c\/p\u003e\n\u003ch2\u003eThe Amplifier\u003c\/h2\u003e\n\u003cp\u003eThe MD-1P delivers 300 watts per channel into 8 ohms. The MD-1, its lower-powered sibling, delivers 150 watts into 8 ohms. Both will drive speakers from 2 to 16 ohms. The amplifier section uses high-efficiency switching topology with advanced PWM processing — Matrix's description of the technology is deliberately general, but the output impedance of under 3mΩ and SNR of 122dB A-weighted are the numbers that matter in practice. An output impedance that low means an extremely high damping factor, which is what gives a solid-state amplifier tight control over speaker drivers, particularly in the bass.\u003c\/p\u003e\n\u003cp\u003eThe MD-1P has two pairs of speaker terminals — gold-plated solid copper — allowing two pairs of speakers to be connected simultaneously and switched between via IR remote. A\/B comparison between two speakers in the same room, or driving a second room from a single unit. The MD-1 has one pair. Speaker impedance for simultaneous A and B use is 4 to 16 ohms.\u003c\/p\u003e\n\u003ch2\u003eThe Digital Processing Section\u003c\/h2\u003e\n\u003cp\u003eThe DAC section uses a mastering-grade AKM chip — Matrix does not specify which in the consumer-facing documentation, but the dual femtosecond clock architecture and FPGA jitter reduction are the same design philosophy applied across the N Series. Two custom femtosecond clocks, one for 44.1kHz-based sample rates and one for 48kHz-based rates, feed a high-speed FPGA that handles frequency division and jitter reduction before conversion. Local playback reaches PCM 768kHz and DSD 24.58MHz.\u003c\/p\u003e\n\u003ch2\u003eVolume Control\u003c\/h2\u003e\n\u003cp\u003eThe preamp section uses a 256-step digitally controlled analogue volume system — finer resolution than the 100-step control in the ND-1 and MS-1c. Range is -80dB to +12dB in 0.5dB steps, with algorithmic optimisation of the voltage output curve to maintain channel balance at low volumes. A 12-step channel balance compensation is available for speaker placement asymmetry. This is analogue attenuation with digital control — not a digital volume control that reduces bit depth, which matters at the power levels the MD-1P operates at.\u003c\/p\u003e\n\u003ch2\u003eAnalogue Inputs\u003c\/h2\u003e\n\u003cp\u003eXLR balanced and RCA unbalanced line inputs handle any analogue source — maximum input levels of 8Vrms on XLR and 4Vrms on RCA, input impedance 47kΩ on both. A bypass mode disables the preamp stage and routes the analogue input directly to the amplifier, turning the MD-1P into a pure power amplifier for use with an external preamplifier or in a multichannel AV system.\u003c\/p\u003e\n\u003cp\u003eA built-in MM phono stage covers vinyl — RIAA equalised, 47kΩ \/ 100pF input impedance, +40dB gain. It is voiced for MM cartridges only; MC users will need a step-up transformer or a separate MC stage.\u003c\/p\u003e\n\u003ch2\u003eDigital Inputs\u003c\/h2\u003e\n\u003cp\u003eFour optical and coaxial inputs handle set-top boxes, gaming consoles, CD transports, and Blu-ray players at PCM up to 192kHz and DSD 2.8MHz DoP. HDMI ARC carries audio from a television at up to PCM 192kHz. USB audio from a computer reaches PCM 768kHz and DSD 22.4MHz native. Bluetooth 5.0 supports aptX, aptX HD, AAC, SBC, and LDAC up to 96kHz — the LDAC codec in particular gives the Bluetooth input more resolution than most wireless implementations.\u003c\/p\u003e\n\u003ch2\u003eStreaming \u0026amp; Network\u003c\/h2\u003e\n\u003cp\u003eThe MD-1P is Roon Ready and also supports Audirvāna, TIDAL Connect, Qobuz Connect, Spotify Connect, AirPlay 2, DLNA\/UPnP, vTuner, and Radio Paradise. Gigabit Ethernet is the primary network connection; Wi-Fi 6 covers situations where a wired run is not practical. The MA Remote App controls everything from iOS, iPadOS, and Android. An NVMe SSD slot on the underside — M.2 2280\/2242\/2230, PCIe 3.0\/4.0\/5.0 — handles local library storage, with SMB sharing and NAS serving to other devices on the network. CD ripping via external USB drive is supported.\u003c\/p\u003e\n\u003ch2\u003eOutputs Beyond The Speakers\u003c\/h2\u003e\n\u003cp\u003eA preamp RCA output at 0–2.2Vrms with 120dB SNR and under 0.0005% THD+N allows the MD-1P to feed an external power amplifier or additional zone. A subwoofer output — also RCA, 150Hz fixed low-pass, 0–2.2Vrms — connects an active subwoofer directly, with the trigger output handling automatic power synchronisation. The MD-1P has dual subwoofer outputs; the MD-1 has one. A 12V trigger input and output handle system power sequencing.\u003c\/p\u003e\n\u003ch2\u003eWhere It Fits\u003c\/h2\u003e\n\u003cp\u003eAt 300 watts per channel with dual speaker outputs, a phono stage, HDMI ARC, and the full Matrix streaming ecosystem in a single 96mm-tall chassis, the MD-1P is genuinely capable of being the only component between your sources and your speakers. It is not a compromise product designed to cover all bases inadequately. The amplifier section has the output impedance and noise floor of a serious amplifier. The streaming section has the same femtosecond clock architecture as the N Series. The DAC section performs at a level consistent with the rest of the Matrix lineup.\u003c\/p\u003e\n\u003cp\u003eWhere a separates system still wins is in the ability to isolate and upgrade individual components — a better clock, a better DAC, a better power stage — without replacing everything at once.

Streamer, DAC, and headphone amplifier. Add headphones or active speakers and you have a complete system. The product is smaller than anything else in the Matrix lineup. The engineering inside it is not.\u003c\/p\u003e\n\u003cp\u003eWhat separates the TS-1 from a competent desktop all-in-one is the headphone amplifier section. It is a fully balanced, high-bias discrete design — not an op-amp output stage, not a chip amplifier. The output impedance is under 1Ω on the 6.35mm output and under 2Ω on the 4.4mm balanced output. For context: low-impedance IEMs and sensitive headphones are affected by output impedance because it interacts with the headphone's own impedance curve and alters the frequency response. At under 1Ω, that interaction is negligible across virtually any headphone on the market.\u003c\/p\u003e\n\u003ch2\u003eThe DAC architecture\u003c\/h2\u003e\n\u003cp\u003eThe TS-1 uses a fully balanced design from the digital input through to the analogue output stage. Each channel is equipped with an AK4493SEQ chip, with the chip's dual DAC units running in parallel — a configuration that improves dynamic range and lowers the noise floor relative to a single unit operating alone. The two DAC chips have completely independent power supply sections, each powered by a dual-channel ultra-low-noise LDO. This is a different chipset from the AK4499EX used in the ND-1 and MS-1c — the AK4493SEQ is a strong-performing chip in its own right, and the parallel dual-unit configuration extracts more from it than a standard implementation would.\u003c\/p\u003e\n\u003cp\u003eClock architecture follows the same dual femtosecond approach as the MD-1 and MS-1c: two compact ultra-low phase noise femtosecond clocks, one for 44.1kHz-based sample rates and one for 48kHz-based rates, with FPGA frequency division and jitter reduction. Each clock runs from its own independent low-noise linear regulator.\u003c\/p\u003e\n\u003ch2\u003eThe headphone amplifier\u003c\/h2\u003e\n\u003cp\u003eThe headphone amplifier is a high-bias discrete circuit — meaning significant standing current flows through the output stage at idle, which keeps the output transistors operating in a linear region rather than switching in and out of conduction as the signal passes through. High-bias operation reduces crossover distortion and generally produces a more natural tonal character. It also generates more heat, which is why Matrix designed the analogue PCB as a separate upper layer — the thermal dissipation from the headphone amplifier needs physical separation from the DAC and digital circuitry below it.\u003c\/p\u003e\n\u003cp\u003eTwo output levels are available on both the 4.4mm balanced and 6.35mm unbalanced outputs to match different headphone sensitivities — a practical necessity when the same amplifier needs to drive 16Ω IEMs and 600Ω full-size headphones without either under-driving the latter or overloading the former. Output power on the 6.35mm output is 1,400mW at 33Ω and 250mW at 300Ω. The 4.4mm balanced output delivers 1,000mW at both 33Ω and 300Ω, with 500mW at 600Ω. The balanced output's more even power delivery across impedances reflects the advantages of the balanced topology at high impedance loads.\u003c\/p\u003e\n\u003cp\u003eThe voicing is tuned specifically for modern high-resolution headphones — Matrix describes maintaining high-frequency extension while subtly restraining the highs for comfortable long-term listening. It is a deliberate tonal choice rather than a measurement artefact, and it is worth auditioning if treble fatigue has been an issue with your current setup.\u003c\/p\u003e\n\u003ch2\u003eLine outputs and the active speaker path\u003c\/h2\u003e\n\u003cp\u003eThe XLR line output delivers 4.5Vrms at 0dB — a high output level well-suited to active studio monitors. SNR is 123dB A-weighted, THD+N under 0.00018% at 1kHz. The RCA output runs at 2.2Vrms. Both offer adjustable output level from 0 to maximum, with two fixed output voltage settings for matching different active speaker gain structures. A subwoofer RCA output handles frequencies below 150Hz with synchronised volume control — the same approach as the MD-1 and MD-1P, useful for a 2.1 desktop setup where the main monitors have limited low-frequency extension.\u003c\/p\u003e\n\u003ch2\u003eInputs\u003c\/h2\u003e\n\u003cp\u003eOptical and coaxial S\/PDIF at PCM up to 192kHz and DSD 2.8MHz DoP. HDMI ARC for television audio. USB audio from a computer at PCM 768kHz and DSD 22.4MHz native — the broadest format support of any input. RCA analogue input for a turntable without a built-in phono stage, a CD player, or any other analogue source; SNR 100dB, maximum input 2.1Vrms. The TS-1 does not have a built-in phono stage — an external phono preamplifier is needed for turntable connection.\u003c\/p\u003e\n\u003ch2\u003eThe DC input\u003c\/h2\u003e\n\u003cp\u003eThis is worth calling out specifically. The TS-1 ships with a switching power supply. It also has a DC input — 12V, minimum 36W, standard 5.5mm\/2.1mm barrel connector — that accepts an external linear power supply. When an external DC supply is connected, the TS-1 prioritises it and disconnects the internal AC supply, retaining only the ground connection. A linear power supply upgrade is a meaningful improvement in a DAC and headphone amplifier at this level, and Matrix has made it straightforward rather than requiring modification or a separate power board. If you buy the TS-1 and later want to take it further, the upgrade path is already built in.\u003c\/p\u003e\n\u003ch2\u003eStreaming and network\u003c\/h2\u003e\n\u003cp\u003eRoon Ready.

It is compact enough for a desk and capable enough to be a primary system without apology. The DC input means it is also not a dead end: a linear power supply upgrade later is straightforward and will be audible.\u003c\/p\u003e\n\u003cp\u003eAgainst pairing a separate streamer with a desktop DAC\/headphone amplifier, the TS-1 trades individual component upgradability for integration and a smaller footprint.

It sits between the NT-1 and the full M Series in the Matrix lineup, and it makes a specific argument: dual femtosecond clocks, Wi-Fi 6, and a DC input for a linear power supply upgrade, in a compact chassis at a lower price than the NT-1.\u003c\/p\u003e\n\u003cp\u003eWhat the TT-1 does not have that the NT-1 does: electrical isolation on the USB DAC output, an external 10MHz clock input, and an SFP port for optical fibre network connection. Whether those omissions matter depends on how far you intend to take the system. For a streamer feeding a good DAC in a well-sorted setup, the TT-1's dual-clock architecture and DC input upgrade path make it a stronger starting point than its position in the lineup might suggest.\u003c\/p\u003e\n\u003ch2\u003eThe clock architecture\u003c\/h2\u003e\n\u003cp\u003eThe TT-1 uses two femtosecond clocks — one for 44.1kHz-based sample rates, one for 48kHz-based rates — with FPGA frequency division and jitter reduction. This is the same dual-clock approach used in the MS-1c, MD-1, MD-1P, and TS-1. The NT-1 uses a single femtosecond clock with a different DPLL architecture. Both approaches target low jitter at the output; the dual-clock design eliminates the need for sample rate conversion between the two clock families, which is a different path to the same goal. Each clock in the TT-1 runs from its own independent low-noise linear regulator.\u003c\/p\u003e\n\u003ch2\u003eOutputs\u003c\/h2\u003e\n\u003cp\u003eOptical, coaxial, and AES\/EBU at PCM up to 192kHz and DSD 2.8MHz DoP — the standard S\/PDIF ceiling.

The USB DAC output handles whatever the connected DAC supports, up to PCM 768kHz and DSD 24.58MHz, with a 5V\/1A low-noise power supply on the port. The NT-1's USB output adds electrical ground isolation between the transport and the DAC; the TT-1's USB output does not.

Do you need USB ground isolation? Do you want an external 10MHz clock input for an SC-1 or other reference clock? Do you need an SFP port for optical fibre network connection? If the answer to all three is no, the TT-1's dual-clock architecture, Wi-Fi 6, and DC input upgrade path represent a strong case at a lower price. If the answer to any of them is yes, the NT-1 is the right product.\u003c\/p\u003e\n\u003cp\u003eAgainst the MS-1c and TS-1, the TT-1 is a transport only — it needs a separate DAC downstream. That separation is what allows you to choose the DAC independently and upgrade it without changing the transport, which is the argument for the separates approach. The TT-1 paired with a capable external DAC can reach a level the integrated streaming DACs cannot, because the DAC is not constrained by the same chassis budget.\u003c\/p\u003e\n\u003ch2\u003ePress recognition\u003c\/h2\u003e\n\u003cp\u003eThe TT-1 is a recent release.

Most audiophiles treat it that way — buy whatever is cheap and reliable, plug everything in, and focus the budget on components that are more obviously in the signal path. Matrix Audio's position is that this is a mistake, and the SS-1 Pro is the argument for why.\u003c\/p\u003e\n\u003cp\u003eThe reasoning starts in digital circuit design rather than audiophile lore. A system capable of supporting higher-speed signal transmission has a higher stability limit — timing errors in high-speed equipment are relatively lower than in low-speed equipment operating at the same actual data rate. A 10Gbps switch running a 1Gbps audio connection is operating well within its stable range. A 1Gbps switch doing the same job is working at its ceiling. The SS-1 Pro has two 10Gbps SFP\/SFP+ ports and eight RJ45 ports at up to 2.5Gbps. The audio equipment connects at 1Gbps or 100Mbps. The headroom is substantial.\u003c\/p\u003e\n\u003ch2\u003eThe Clock System\u003c\/h2\u003e\n\u003cp\u003eThis is where the SS-1 Pro separates from the SS-1 and from every other switch you will find at any price. Inside is a femtosecond clock feeding a high-precision ultra-low phase noise RF synthesizer. The RF synthesizer generates the clock signal that drives the switch's main controller — it is the same architecture Matrix uses in the NT-1 transport, applied here to the network infrastructure that feeds it.\u003c\/p\u003e\n\u003cp\u003eTwo clock modes are available. In internal clock mode, the femtosecond oscillator is the reference for the RF synthesizer, which outputs a stable, low-phase-noise clock to the controller. In external clock mode, a 10MHz reference signal from an external source — the Matrix SC-1, or any compatible 10MHz reference — becomes the input to the RF synthesizer via DPLL, producing a clock that is synchronised to the external reference. The external clock input accepts 10MHz at 50Ω, sine or square wave, the same specification as every other Matrix component with a clock input. If you are running an SC-1, it can discipline the switch as well as the transport and DAC.\u003c\/p\u003e\n\u003cp\u003eThe SS-1 — the standard version without the RF synthesizer — uses a femtosecond clock as a direct reference for the main controller. It is a simplified but still serious clock implementation. The external clock input and RF synthesizer are exclusive to the SS-1 Pro.\u003c\/p\u003e\n\u003ch2\u003eThe Ports\u003c\/h2\u003e\n\u003cp\u003eTwo dedicated 100Mbps\/10Mbps RJ45 ports are provided specifically for audio equipment. Matrix's reasoning: connecting audio devices to lower-speed ports reduces the potential for bit errors during data transmission. These ports use independent sockets with wider spacing than the main array, accommodating high-end Ethernet cables without crowding. All Ethernet ports use 10Gbps-grade independent Ethernet transformers with individual metal shielding on each signal transformer — radio frequency interference resistance at the port level rather than just at the enclosure.\u003c\/p\u003e\n\u003cp\u003eThe two SFP\/SFP+ ports support up to 10Gbps and accept optical fibre or RJ45 modules. Running the upstream network connection and an audio streamer through SFP ports on optical fibre creates complete electrical isolation between the network infrastructure and the audio equipment — ground-borne noise from upstream devices has no path to the audio side. This is the same isolation principle as the SI-1 network isolator, achieved through the switch architecture itself rather than a separate device.\u003c\/p\u003e\n\u003cp\u003eThe SS-1 Pro has six 2.5Gbps RJ45 ports; the SS-1 has four. Both have the same two 100Mbps dedicated audio ports and two 10Gbps SFP\/SFP+ ports.\u003c\/p\u003e\n\u003ch2\u003ePower Supply\u003c\/h2\u003e\n\u003cp\u003eThe SS-1 Pro runs on a custom o-core toroidal transformer — an optimised core geometry that reduces flux leakage compared to conventional toroid winding — combined with high-speed Schottky diodes and close to 10,000µF of audio-grade filtering capacitance as the first stage. Six ultra-low-noise LDO regulators distribute clean power to the clock system and the main controller from that filtered supply. The main controller chip sits on a large passive heatsink — no fan, no switching noise from cooling hardware.\u003c\/p\u003e\n\u003cp\u003eThe SS-1 ships with a switching power supply but includes a DC input — 12V, minimum 18W, standard 5.5mm\/2.1mm barrel connector — for an external linear power supply upgrade. When DC is connected, the internal AC supply disconnects automatically. The SS-1 Pro's internal linear supply is already at a level the SS-1's DC upgrade path is trying to reach.\u003c\/p\u003e\n\u003ch2\u003ePractical Details\u003c\/h2\u003e\n\u003cp\u003eThe Ethernet port LEDs are switchable off via a button on the rear panel — the same listening-environment consideration as the SI-1. The 16K MAC address table is substantially larger than the SI-1's 2K table, appropriate for a switch serving multiple devices on a network rather than a two-port isolator. The chassis is CNC-machined aluminium with a reinforced steel base. Four isolation feet are included; the design accommodates three-foot placement for tuning and surface compliance.\u003c\/p\u003e\n\u003ch2\u003eWhere it fits\u003c\/h2\u003e\n\u003cp\u003eThe SS-1 Pro belongs at the last network node before the audio equipment — between your router or upstream switch and the Matrix streamers, DACs, or other network audio devices. Used with optical SFP modules on the upstream port and the audio streamer port, it provides the same electrical isolation benefit as the SI-1 while simultaneously serving as the final switch in the network chain. Used with the SC-1 on the external clock input, the entire digital chain — switch, transport, DAC — runs from the same reference clock.\u003c\/p\u003e\n\u003cp\u003eAgainst the SI-1 network isolator, the SS-1 Pro is a full switch rather than a two-port pass-through — it handles multiple audio and non-audio devices simultaneously.

The SS-1 Pro adds an RF synthesizer between the oscillator and the controller, and an external 10MHz input for SC-1 pairing. The SS-1 has neither. If you are running an SC-1 and want to discipline the switch from the same reference, the SS-1 Pro is the right product.
