I think what gets me with the Audiophile/power discussion is that it wants to go everywhere all at once with no single principle to adhere to.
The ideal AC circuit:
- Does not waver in voltage
- Is free of noise
- Is a perfect 60 Hz signal
The problem is that the power coming in from the transformer and the demands of your home and the homes around you are noisy. OK, I get it. But the last thing you want is a wide-band perfect conductor. Ideally you want filters that remove as much noise as possible and some way to keep the voltage stable regardless of the load.
Well, you can’t have stable power because the incoming voltages are always fluctuating. A giant gauge wire will reduce the sag during musical playback but it can’t do a thing to change what he power company sends you.
