EXPIRED For Sale SW1X Level II + with USB Digital Analog Converter (DAC)

Further Information

Interesting NOS dac from boutique manufacturer in UK. High quality parts used through, reminiscent of Audio Note with quality chokes, tubes and caps throughout. Even the USB input board utilises a nu-vista style tube in the signal path. 

The spdif input in this dac is unbelievably good.

Description:

DAC II comes 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 level 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 SW1X copper conductors & dielectric- the same ones that are employed in our Genesis and Opus cables.
