What got me thinking about it was a agon discussion I was reading where it was suggested that the receptacle and plug metals should be of the same metals.. Various other posts have suggested something similar, without everyone agreeing, of course.
The main research I've seen on this was done by the military a while back, where it was shown to cause distortion of a measurable degree relative to other factors. I'll try to find some links to the research...
I'm definitely not saying that there aren't other things that screw up a signal, but this particular 'issue' is what is currently piquing my interest.
Also, I'm not sure AC power should be considered a signal.. Though, from what I understand, distortion in its waveform is to be avoided..
