Jea, I can only go by my experience, exactly the same problem, dedicated ground fixed it and a nice sonic boost to match.
I'm also not saying it can't be RFI, just a long, long shot. He didn't have the problem with the other amps and same cable, points to amps as problem. It could be the other amps did a better job of filtering out EMI and RFI.
I just think dedicated grounds are the resolution to all these sorts of problems, I'm not alone, many are using dedicated grounds.
