Thanks, I figured it was very similar to how an HDMI type device works, almost identical.. Quality will be built depending on the end device. So it makes sense that the quality will be in the USB dac itself doing its job more so than the device storing a file.
This is why I actually put that question out, which is why I can't see any advantage to going the route of a standard Coax digital or Optical cable connection converted at the music serving device in the first place, it seems to me it is much more sensible to put a little more money into a USB DAc these days, Eliminate a 300 dollar Coax digital cable for example and replace with a decent USB then just let a standard computer, or music server device do its job on its end and the DAC take on clocking it and allowing the DAC also the actual responsibility to make it sound good!
Seems to eliminate much of the guesswork in cabling, cost, and basically only one conversion done at the input of the USB Dac once data arrives.. I really don't see putting a cheap USB card on a computer that outputs the Digital coax etc.. at the main device, but of course I can understand people with really good old school DACS wanting to keep their old DAC and this is the only way to convert it price effectively.
