hospital grade or commercial grade receptacles ?

Any power cable will do mister. Grab a physics book if you dare! What IS imporpartant and should be considered is a balanced transformer/AC conditioner. Most of the big recording studios and mastering labs use them. I do too. No hocus pokus here. These devices (ie: Equitech 5Q) WILL make a significant sonic difference. Much better soundstage, better transient/dynamic response, and much tighter, accurate bass. Garbabe in;Garbage out. No BS sir.

Quantumavman you obviously have not paid any attention to anything that has been said up till now. I have grabbed several physics books and they offer nothing to the subject being discussed.

Nrchy, you are right, of course, but Quant...does not want to be confronted by the facts. His argument is curious though as he argues that most things don't matter but that balanced does.

I tried plugging a physics book into a hospital-grade receptacle, but it made every album I played sound like "Irvrobinson's Greatest Hits."

Albertporter...When the dog barks the guy hears something else, because he wants to. He is happy. So am I with my dog who doesn't need human speach to communicate.

Let's move on :-)
