1. After generation, several transformers, miles of wire, hundreds of other loads, distribution lines, a meter, and your breaker panel(s), the receptacle, wall plate (!), and power cord are going to make audible improvements on the sound.
2. Santa Clause, the Easter bunny, and Superman are all real.
Gee, which statement is more believable? :roll:
We've even seen $21K speaker cables. PJ and I refer to such inane equipment purchases as "the emperor's new speaker wires." I like A/V as much as anyone, but I can't afford to be that ridiculous.
I know many home-theater people who are afraid to use the audio/video switching in their A/V receivers because they're afraid that will degrade the signal, and prefer to use the multiple inputs on the TV instead.
I counter with the fact that they're watching/listening to a recording to begin with, and not the live event itself. How do they justify that to themselves? After all, isn't that the ultimate "signal degradation?"
