Not an off-the-shelf chip. Not a modified reference design. A discrete DAC architecture where every stage, from circuit layout to power management to clocking, was designed by Lumin specifically for this product and this application.\u003c\/p\u003e\n\n\u003ch2\u003eThe Discrete DAC\u003c\/h2\u003e\n\n\u003cp\u003eDual DAC, one per channel. By building the converter from individually selected discrete components, every aspect of the digital-to-analogue process can be optimized without the constraints that integrated chip designs impose. Circuit layout minimizes interference and preserves channel separation. Custom circuitry and refined power management reduce electrical noise in ways that chip-based implementations can't access. The clocking and conversion stages implement directly without intermediate frequency dividers, supporting precise timing throughout the signal path.\u003c\/p\u003e\n\n\u003cp\u003eThe analogue stage uses a dual-mono dual-stage power supply — isolation between the two channels at the power supply level, not just the circuit level. The all-new output buffer was designed alongside the discrete DAC as a matched system.\u003c\/p\u003e\n\n\u003ch2\u003eThe Platform\u003c\/h2\u003e\n\n\u003cp\u003eSolid billet CNC aluminum chassis and matching external dual-toroidal linear power supply — the same construction approach as the X1, now housing a more capable DAC. Femto Clock system with FPGA-based distribution. SFP fibre network input with a built-in network switch for galvanic isolation. USB digital audio output supporting native DSD512. PCM and DSD upsampling up to DSD256. Leedh Processing lossless volume control.

Reviewers consistently identified the discrete DAC as a genuine step forward from the X1's chip-based implementation, with improved spatial presentation and low-level resolution as the most frequently cited improvements.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDAC: Custom dual Discrete DAC, one per channel, Lumin in-house design\u003c\/li\u003e\n\u003cli\u003eChassis: Solid billet CNC aluminum\u003c\/li\u003e\n\u003cli\u003ePower supply: External dual-toroidal linear, matching CNC chassis\u003c\/li\u003e\n\u003cli\u003eAnalogue PSU: Dual-mono dual-stage\u003c\/li\u003e\n\u003cli\u003eClock: Femto Clock system with FPGA distribution\u003c\/li\u003e\n\u003cli\u003eNetwork: SFP fibre with built-in switch\u003c\/li\u003e\n\u003cli\u003eUSB output: Native DSD512\u003c\/li\u003e\n\u003cli\u003eUpsampling: PCM and DSD up to DSD256\u003c\/li\u003e\n\u003cli\u003eVolume: Leedh Processing lossless\u003c\/li\u003e\n\u003cli\u003eOrigin: Made in Hong Kong\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eAuthorized Lumin dealer.
