I would say for me, it all depends.
at one point I had my amps into a PS Audio p1000, and my front end into a P300, all into the same wall circuit. I sold the p300 and found i huge detriment. I bought another p300 and all was well again.
I then found an ESP Reference power strip, decided to swap the stuff from the P300 into the ESP. Due to some power cord lengths, I could not put all the prior P300 stuff into the ESP. I didn't care for the results-----I then decided to use a different outlet for the ESP and had all front end into the ESP----now the ESP sounds better than the P300. I have been too happy with the current set up to tear it down and try the P300 into the same separate circuit--but I guess the moral of my story is, to make sure you can to spread the system to as many separate outlets as possible
