audiophile quality cheater plugs?

I can't remember which power cord company I saw makes audiophile quality cheater plugs, can anyone help me ?
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.
