As a standalone preamplifier, it is also the most fully equipped component Unison Research has offered at this level: tube input stage, built-in DAC, integrated phono stage, balanced and unbalanced outputs, subwoofer output, and 12V trigger. Everything from a single chassis without compromise.\u003c\/p\u003e\n\n\u003ch2\u003eThe Design\u003c\/h2\u003e\n\n\u003cp\u003eThe front panel is machined from a solid 15mm aluminum block — the same manufacturing approach as the DM v2. The 2mm aluminum top cover wraps continuously around the enclosure. Wooden inserts reference the historic Unico logo. The Unison Research logo functions as the power switch. Midnight Black and Velvet Gold — both worth seeing in person before deciding. The Velvet Gold photographs differently than it looks under light.\u003c\/p\u003e\n\n\u003ch2\u003eThe Circuit\u003c\/h2\u003e\n\n\u003cp\u003eThree-stage, fully dual-mono, zero global negative feedback throughout. The first stage uses two ECC83\/12AX7 Gold Lion valves in pure Class A — higher gain and lower noise than the ECC82 used in the DM v2, which is the appropriate choice for a preamplifier stage where the signal is at its most delicate. The subsequent solid-state stages provide drive capability and output impedance without adding character of their own. Gain structure and output impedance of a solid-state preamplifier; harmonic quality and spatial presentation of a tube input stage. Each technology doing what it does best.\u003c\/p\u003e\n\n\u003cp\u003eVolume control uses a high-quality integrated circuit with precision resistors and infrared remote — perfect channel balance at all volume settings, without the tracking errors that mechanical potentiometers introduce at low levels.\u003c\/p\u003e\n\n\u003ch2\u003eThe DAC\u003c\/h2\u003e\n\n\u003cp\u003eBuilt-in DAC uses the ESS Sabre ES9018K2M chip with USB, S\/PDIF coaxial, and Toslink inputs. Not a token digital input — a properly implemented DAC stage that handles 32bit\/384kHz PCM and native DSD. It won't replace a dedicated flagship DAC, but it's genuinely capable and covers the majority of real-world digital listening needs without requiring an additional box.\u003c\/p\u003e\n\n\u003ch2\u003eThe Phono Stage\u003c\/h2\u003e\n\n\u003cp\u003eIntegrated MM\/MC phono stage with passive RIAA equalization. Moving coil and moving magnet cartridges both accommodated. A passive RIAA implementation is the right approach at this level — active RIAA introduces gain stages that can add noise and colorations that passive equalization avoids.\u003c\/p\u003e\n\n\u003ch2\u003ePress Recognition\u003c\/h2\u003e\n\n\u003cp\u003eThe Unico PRE v2 has been reviewed by Hi-Fi+, Hifi News, and Positive Feedback alongside the DM v2. Reviewers consistently highlighted the phono stage as superior to what the price would suggest, and praised the zero-feedback architecture's effect on spatial coherence and midrange transparency.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eInput stage: Class A ECC83\/12AX7 Gold Lion, two valves, dual-mono\u003c\/li\u003e\n\u003cli\u003eFeedback: Zero global negative feedback\u003c\/li\u003e\n\u003cli\u003eDAC: ESS Sabre ES9018K2M, USB\/S\/PDIF\/Toslink, 32bit\/384kHz PCM, native DSD\u003c\/li\u003e\n\u003cli\u003ePhono: MM\/MC with passive RIAA\u003c\/li\u003e\n\u003cli\u003eOutputs: Balanced XLR, RCA, dual subwoofer, 12V trigger\u003c\/li\u003e\n\u003cli\u003eVolume: Precision resistor IC with IR remote\u003c\/li\u003e\n\u003cli\u003eFront panel: 15mm solid aluminum\u003c\/li\u003e\n\u003cli\u003eFinishes: Midnight Black, Velvet Gold\u003c\/li\u003e\n\u003cli\u003eOrigin: Handcrafted in Italy\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eAuthorized Unison Research dealer.

It is also, unmistakably, Italian — in the way that description carries real meaning in high-end audio.\u003c\/p\u003e\n\n\u003ch2\u003eThe Design\u003c\/h2\u003e\n\n\u003cp\u003eThe v2 marks a deliberate shift in Unison Research's aesthetic. The 15mm solid aluminum front panel — machined, not extruded, not folded — sets the tone from the first moment you see it. The 2mm aluminum top cover wraps continuously around the enclosure for structural rigidity and visual coherence. Wooden accents remain, used sparingly now as a reference to the historic Unico logo rather than a dominant visual element. The Unison Research logo functions as the power switch. Midnight Black or Velvet Gold.\u003c\/p\u003e\n\n\u003ch2\u003eThe Architecture\u003c\/h2\u003e\n\n\u003cp\u003eTrue dual-mono. Each channel has its own 750VA encapsulated toroidal transformer, potted and shielded against electromagnetic interference. The two channels share a chassis and nothing else of consequence — power delivery, regulation, and signal paths are fully independent. Channel separation that a shared-supply design cannot achieve.\u003c\/p\u003e\n\n\u003cp\u003eThree amplification stages. The first is a Class A tube stage using one ECC82\/12AU7 Gold Lion valve per channel. This is the tonal foundation of the amplifier — speed, fine detail, the emotional texture of the music all originate here. The second stage is solid-state, operating transparently to adapt the signal to the output. The third stage is where the DM v2 introduces A.S.H.A.\u003c\/p\u003e\n\n\u003ch2\u003eA.S.H.A. Technology\u003c\/h2\u003e\n\n\u003cp\u003eAnalog Synchronized Hybrid Amplification is Unison Research's new output topology, introduced for the first time in the DM v2. It operates in Class A-AB using MOSFET output devices, delivering high power with lower distortion and better thermal behavior than conventional Class AB implementations. The bridges to 650 watts mono configuration makes the DM v2 a serious option for demanding loudspeakers in large rooms.\u003c\/p\u003e\n\n\u003ch2\u003ePress Recognition\u003c\/h2\u003e\n\n\u003cp\u003eThe Unico DM v2 has been reviewed by Hi-Fi+, Hifi News, and Positive Feedback. Hi-Fi+ called it among the finest hybrid amplifiers available at any price, with particular praise for the A.S.H.A. output topology's combination of power and musicality.
