Do I need higher quality power cords?

@shadorne,@roberjerman, I always find it interesting when those folks who cannot hear differences in power cords ( as well as some other upgrades / tweaks ), claim these sonic differences do not / cannot exist, and then talk about voodoo or meditation. Upgrading the power cord of a piece of equipment is not necessary ( it is not necessary to upgrade tubes either ). But we do it to reveal greater musical involvement with our systems. In each of your cases, one of three things are occurring : 1 = The system is not up to the resolution level in which it can be heard ( including the room acoustics ). 2 = You have not tried any. 3 = You are deaf ( or just have weak hearing / inexperienced hearing ). Oh, I am sorry. There is a 4th. You guys may have joined the troll bandwagon. Nothing you could say will convince me ( and others ) it is our imaginations. I am sorry for my bluntness. Enjoy ! MrD.

Excellent post by MrD.  I agree totally.

Sounds like a case of inflated ego mixed with expectation bias, nothing more and nothing less.

Sorry for my bluntness, MrD.

mr D. I don’t dispute your finding. It is indeed quite possible you hear a difference because your equipment power supply is so woefully inadequate. This is NOT the same as “resolution level” unless you spend all your time listening to the AC 60 Hz power signal and other harmonics and related noise coming out your speakers.

Wow, inadequate power supplies in my equipment. Shadorne, have you, or have you not, tried a different cord on any of your components ? You must have the only equipment who's power supplies are not woefully inadequate. @spotcheckbilly, thank you for coming to the party. 10 posts. I am quite sure your numbers will be in the hundreds in no time. Enjoy ! MrD. FWIW, this is always fun.
