What is the general consensus as to where to best place your highest quality PC excluding the power amp. I've seen opinions from: it s/b the first cable from the receptacle, to it s/b the piece of ancillary equipment likely to generate the most electrical noise.
Why exclude the power amp? I have two power amps, each has its own AC line, and each has its own Shunyata power conditioner, and Shunyata cables. The system sounds much better than just having the amps plugged directly into the wall.
