Short answer is No.i have a question regarding the usb connection between the dac and the pc.
does it work if you use a data only cable, no 5v connection on the cable that`s connecting the dac to the pc?
longer answer:
to begin with no such cable exists commercially. So you have to make or modify one.
Secondly, if you could get your hands on one, then it wouldn't work!
you see, the +5V tells the DAC to switch to USB input. without it, you get no sound out.
