I'd be careful with that separate neutral suggestion.

1.) Wiring has to be to code, or it should be.

2.) Even if you break the neutral, you still have the hot 
lead and ground lead. Everything ties together back at the 
box anyway, and a wire will radiate no matter what you do if 
you have an RFI generator connected to it.

He probably is confusing audio ground loops with RFI, two 
very different things.
