For sale is this very fine Chinese 24 bit/96Khz DAC. I have replaced the stock tube with a JAN 5670W tube for slightly better sound. This DAC is a 220 volt version, but for the listing price I will also send a Goldsource ST-100 step-up/step-down transformer. I will also send the original stock tube and an extra JAN tube. The price for this on E-Bay is about $200, so for much less money you get a burned-in unit with better tubes and a power transformer. Technical details about this DAC are available all over the internet. It is basically the same item as the Maverick DAC and the Grant Fidelity DAC-09. I pay shipping for full-price offer.
