RE: Let me get this out of my system...

Mercman, I do have an async USB DAC in my system and I am well aware that it is not perfect.

I am not sure what you mean by "isolate electrical noise from the computer that is passed down the USB cable".

I have done electrical engineering and have designed my own circuits but I'm still scratching my head on this one.

If you are completely reconstructing the signal timing, which is what an async USB DAC is supposed to do, then any noise from the input should be isolated from the DAC. Unless of course you were such a poor designer that the input signal is causing power rail modulations.
