General Asylum: Question about equipment in wall outlets by Cliff D.

Ok, I have a system that I use for audio only.. It's got a receiver (Yamaha) and a CD Player (Pioneer) and Speakers with no subwoofer (Mission)... I'm plugging my receiver and cd player which each have a plug (therefore two plugs total) in which I plug them both into a wall. (One on top and one in the bottom one... which fills that wall outlet.

Ok, I've heard in the past a rumor that if I was to ADD a component to my stereo and wanted to use a power bar (that holds 6 electrical outlets instead of 2) to plug 3 or 4 components into that power bar which is plug into the wall... I've heard the rumor that using a power bar or other adapter to do this I am going to lose sound quality/power etc.. which will reduce the quality (sound, power) overall out of my 3 or 4 components plugged into the power bar is this true ?

If I was to use an extension cord to plug my 3rd component into another electric wall outlet and the 4th component into a DIFFERENT extension cord to that same wall outlet but either above or below into... This way I'm using each component (if there are 4) in a separate electric wall outlet which if the rumor is true will not degrade my system.

I really would like for my system to plug 4 components into a power bar with absolutely no loss of quality at all.

Thanks folks
