Hi,
I go over USB, but in the USB line I have a box called iUSB, I have been told it is a power supply.
So:
Laptop -> USB -> iUSB Box -> USB -> DAC
When I asked about USB vs SPDIF I was told that SPDIF is really bad. This makes sense to me as when I was buying a serious HiFi in the 90's I ended up with a Naim CDS, two boxes, but not separate Transport and DAC as was the fashion then. In some ways the iUSB and Dac is similar, one Power box and one for all the processing and audio.
