A couple of things you could do. One use the cheater plug, if you are using a standard wall outlet then there is an additional inch of the same grade of copper, brass etc that is used in the outlet. So you won't lose much from a performance standpoint. The trade off on the performance difference should be outweighed by the elimination of the hum. Two, try to wrap the ground pin in a thin layer of electrical tape to insulate the ground from conductivity. Make sure you leave enough tape on the plug itself so the tape can be pulled from the outlet whenever you move that cord for any reason. I would not disconnect the ground for a couple reasons. If you ever move and forget to reconnect it or you lose grounding for the other plug in on that outlet.
Ground Cheater plug or....
Maybe this isn't a good idea, but I thought I'd ask anyway.
I have what I believe to be a persistent ground loop hum from my amplifier. It's quiet, inaudible if music playing or unless you're standing next to the speaker, but knowing it's there is annoying.
I've heard suggestions to use a cheater plug to defeat the ground, but it seems counterintuitive to stick a 35cent plastic plug between expensive cables and power supplies. My question is, couldn't you accomplish the same thing by disconnecting the ground wire in the outlet, and still exact the benefits of better cables?
I'm sure the fire marshall would disapprove, but I'd like to hear what the hi-fi nuts have to say.
Cheers!
