Jea48 -- That was an excellent paper; thanks!
However, it does not really address my question, which as you appear to realize was about having MULTIPLE dedicated lines powering different parts of the same audio system. The author describes his own setup, which has a single dedicated line running to a receptacle into which he plugs a diy power strip + switch. He does provide some good information as to connection order, such as connecting the power amp to the end of the strip closest to the incoming ac.
I understand your point about decoupling the power supplies of each component from the supplies of the other components, particularly to isolate digital components from analog components. But I'm uncertain how to reconcile that with the concerns I expressed, about ground loops and the possibility of having ac ground points that are offset from each other at least at high frequencies.
When I get a chance I'll try to take a look at the AA archives you mentioned.
Thanks again,
