Model: Standard


DAC II is based on 2 x PCM56 DACs- probaly the most refined sounding R2R DACs ever created. It come equipped with more sophisticated power supplies and powerful 6N6P/6N30P/5687/E182CC valve output stage with 6X5GT (or 5Y3) valve rectification. The DAC II has a similar analogue & musical character akin to DAC I but with a step up in low level musical refinement and presentation on another level. The circuit design is pure and elegantly simple with only one decoupling capacitor per channel in the signal path. Everything from input to output, including the mains inlet, the whole signal path is wired with specially selected copper conductors & dielectric- the same ones that are employed in our Genesis and Opus cables.

The DAC II is currently available in STD, SPX or Balanced versions.
