Amp ac cable connection

like the OP said, he prefers comfort to excitement for music listening...

and also psinyc, it's not just the outlet you use, but all the outlets on that line, and really all in the home...Charles Hansen of Ayre, commented here a bunch of years ago, that one of the best things you could do for your music system was to unplug your TV and surround sound system...mine is on a different line, and I didn't want it to help because it's a nuisance to do, but it made a nice improvement...

Through psinyc own listing session he is supporting what I am saying. Power conditioners restrict the full potential of your equipment

I'm not sure what you mean by "full potential." I can tell you - with measurements to support it - that faulty AC power can limit the performance of audio equipment - especially power amplifiers - and that the right power conditioner can restore performance. That's especially true when the AC line has a bad power factor.

This isn't mumbo-jumbo, but very basic stuff.
