I have a customer with tons of money to spend on his audio/video equipment. Thus far, he has nearly spent 1 million (this is not a joke). He has told me that an audio/video expert has told him he should rewire the power feed to his subpanel with a special high end wire. Currently, this subpanel feeds all his equipment. This will give "cleaner" AC power according to the expert. He didn't have any details as to what the wire was, he just knew it was 30k for a roll(125' ?).

Has anyone any experience with this sort of application or know if this special wire will actually give measurable results? I understand that low-voltage cable for the system between components is important as is surge protectors, but why would a better line to feed it be necessary? Where would you stop with this idea... re-feed the pull to the transformer at the street?

Your thoughts would be appreciated.
