SW1X Audio Design™ DAC II Performance Level 2 D to A Converter


DAC II is based on 2 x PCM56 DACs with more sophisticated power supplies and powerful 6N6P/6N30P/5687/E182CC valve output stage with 6X5GT (or GZ34/5Y3/5R4 as an option) valve rectification. The DAC 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 more dynamic sounding active I/V (current- to voltage conversion) stage is directly connected to the single ended class A, zero feedback, anode follower 6N6P/5687 tube output stage. The whole circuit has only one decoupling capacitor per channel in the signal path. Everything, including the whole signal path is wired with specially selected copper conductors & dielectric from input to output. The DAC II is also available in the Special, Balanced or Signature version, which is limited in supply due to scarcity of the exotic materials & components.
