"But even then the USB cable still has an effect. Hey so does analog cables."
Since the effect may not be measurable, I believe it is necessary to concoct some clever experiments to narrow in how the differences and cables may be coupling into the audio system. That would have to be the first step in solving these problems (or as John suggested, finishing with the second order problems so as to be able to move on to the third order problems).
I don't believe it will require expensive instrumentation to do these experiments, but after the problem has been isolated then it may require expensive instrumentation to be able to select circuits that minimize the unwanted coupling. But at least one will know where to work. (It may be that some know the answer here, and are keeping quiet for commercial reasons. If I were in that position I would just keep silent, because even to admit there was an answer would be to help the competition.)
There are some things that probably do not affect the sound. I'm not sure where the line is drawn, but I think it is safe to say that the Ethernet cable connecting the HDtracks.com download server to the nearby hub is not going to affect the sound quality experienced by any of their customers. :-)
