Jea and Jmcgrogan, I thought you two already knew that you can't teach a pig to sing, and I'm certainly not going to try. I think my post explained everything pretty clearly. If you already know it can't make a difference, then I guess it certainly isn't worth your time to actually try it.
For those who are open minded enough to try things like power cords, outlets, dedicated lines, etc., they will actually get to enjoy their systems even more. Those that don't won't.
Good listening,
M
