Hi,
I unplugged the cable-TV feed and the hum stopped. I have a power bar and all my components are on the same circuit. The bar is equipped with an entry and an exit for cable-TV. I'll try passing the TV signal through the bar to see if it makes a difference or not. Else, I guess I'll have to buy a video ground isolator.

I forgot to mention that there are three outlets called "transformer spaced outlets" on the powerbar in addition to an entry and exit for cable-TV. Not knowing what these were, I decided to plug all my components in the other "regular" outlets when I installed my HT. Could using one of these outlets for the sub be a solution to my ground loop problem? Thanks again for your much appreciated help.

Run the cable through the power bar inlet/oulet, I know of a few people that have had their ground loop issues resolved with this simple solution.

"Transformer spaced outlets" are just outlets with extra space between them for AC/DC transformers, aka wall warts.

I had the same thing with the cable and bought the Axiom ground isolator. It worked like a charm, no more hum.

I had a ground loop hum with my ep500 caused by my TV cable. I had to purchase the axiom ground isolator to solve the problem. No problems ever since.
