audiophile quality cheater plugs?

You should NOT use cheater plugs if your equipment has a three prong plug.Find your soucrce of hum within your cables or cable entering the house.

Its ok to use cheater plugs. Your innerconnects will ground the system. Krell covers this in their owners manual. I would prefer to find the offending loop and remove it. It can be a trying process to say the least.

Ninja is right!

Or you can just cut the ground pin off. Ouch! Thats what i've done with the amps in both my systems. Floating the ground is really not a big deal. Many people do this a never have a problem with it. I've done it for years and I leave my stuff on 24X7.

Ninja and Drrdiamond are absolutely incorrect and dangerously so!!! Not all interconnects are grounded at both ends. This could lead to a situation where a piece of equipment is floating and that is dangerous. If you must use a cheater cords make sure that you ground all of the chassis to one point, which will probably fix the ground loop, but do not under any circumstances rely solely on the interconnects for ground.
