Matthew: I actually had to put all my amps on seperate power circuits than my other gear in order to get rid of my hummmmm. Cheater plugs worked somewhat, but I didn't like the idea of externally lifting the ground on amps.
I also noticed that in my system I can tell when ANY connection between my 950 and a coax cable is made. For example, hooking up a coax cable to my VCR and then running ONLY my audio outputs to the 950 causes a humm unless I used the Holland isolator. Also, when I ran a coax cable connection to my TV and then also had ANY video connection from my 950 connected, humm. The only way I could remove all of the humm was to use multiple Holland and Magic Isolators between EVERY RF coax to component connection in my system.
