"I have actually rewired ( or had rewired by a tech ) a different path separating the power line to the audio line within the chassis, and hearing a cleaner background when listening to music through these products afterwards. "
Two comments:
1. Have you compared identical stock and rewired amps? If not, then you have no firm basis to demonstrate, at least informally, that there has in fact been a difference sonically. This is not so much a challenge to what you discuss in terms of hearing a difference, but an encouragement for you to test your own perceptions. Just as it is shocking to hear that there are no sonic differences between broken in and warmed up gear versus new and stone cold gear, so also you may be shocked to discover far less of a difference than you believe.
2. It sounds like this was not a truly apples to apples comparison, if the tech changed the amp in any physical way in regard to the power path. If there was any change to the power pathways, i.e. added wire, then it would not be demonstration of proximity, but of altering the power pathway. It would be interesting to learn whether the power layout was or was not altered. It depends, I think, on what you mean by "rewired a different path". :)
Finally, this could be a nice enhancement to amps, should it turn out to have efficacy when compared to a stock amp. Yet, the principle still would hold true that any given other amp of any particular design could outperform it. If you compared the rewired amp to, say, 6-10 others and found the rewired one consistently superior in a variety of systems, that would be impressive!
