Whole heartedly agree with what many have said here, here is my experience in my own system and setting up a bunch of friend's systems:
(1) Install at least 2 dedicated lines, one for your amplifier and one for signal components. This should cost around $450 give or take depending on the length of the runs. Provided HUGE returns on the cost
(2) On those 2 dedicated lines, install a high quality receptacle; here are some excellent ones: Furutech GTX-D(G) gold plated $180, Furutech GTX-D(R) rhodium plated $210, Oyaide R-1 $180 (NOT the SWO series), and for much less money Acme Audio Labs silver plated,Cryo'd, CFC coated $75 or $85 depending on model.
I personally don't prefer the Rhodium plated Furutech (too bright in my systems), but a lot of people love that receptacle....and the Acme Audio Labs is just ridiculously good for $80 give or take for a silver plated plug. In my new audio room, I am installing 3 dedicated lines; two with the Furutech GTX-D(G), one with the Oyaide R-1, and the non-dedicated with the Acme.
(3) Find power conditioner/supply of your choice, but only for signal components; do not plug your amp into the conditioner
(4) Plug your amp directly into one of the new dedicated lines with updated receptacles
(5) I use and can highly recommend the Anti-Cables Level 3, they are amazing for the price. Zavfino and RAMM Audio make brilliant cables that are OCC copper, and affordable. I have even better cables that I have built boutique Japanese copper, but just the bulk cable and plugs cost twice what the others cost.
