Curing ground loop hum with a power conditioner ?

It probably won't help. My experience is that ground loops are very difficult to diagnose and eradicate. I have tried power conditioners, RF stoppers, cheater plugs, etc, and nothing works, other than finding the offending piece of equipment.

I admit that I am skeptical about the value of power conditioners in general. But I think (hope) that most would agree that, whatever good they do, they do not particularly help with ground hum.

I had the same problem and switched to the Monster HTS1000 and that did the trick. I did not even have to connect the amp or any of my other devices to the monster, only the cable connection. I returned the 1000 though because I actually wanted to connect my equipment and got the 2000 off ebay for $105. You can try the monster buy buying it at circuit city,best but, or goodguys where you can take it back and get some better of ebay or used. I also tried the mondial magic, but upon installation it did nothing for that system and reading the instructions states that it is only for properly grounded cable systems.

Guys you are really making this complicated. If the ground loop hum is from the cable all you need is a simple inexpensive filter for your cable between the outlet and the box. Isomax makes this and can be found on the web or an electronics store. Using a cheater plug on something you might want to provide surge protection doesn't sound like a good idea to me.

I agree with Ksales. I have used a Mondial MAGIC ground isolation transformer for my cable TV for over 10 years. Since it was installed, I have never had ground loop hum or needed cheater plugs. I believe they are available at Audio Advisor... a used one was recently sold right here on Audiogon.
