I recently solved the problem with a $12 Holland Electronic ground loop isolator from a local A/V shop. Solved the problem. A friend of mine suggested a homemade 75-300-75ohm resister series to do the same thing (see post above). I still kick myself for not visiting Radio Shack and saving $4 bucks. I could almost by a used CD. Have fun! Kurt
Cable TV causing system ground problems!
After responding to another thread about powerline products. ..I wanted to post what you might call a warning...or at least a "heads-up". Cable feeds...be they for TV or cable internet..or FM, can cause real problems for your stereo. The ground on cable can have DC and other problems..that if connected to your system through interconnects from unit to unit, or to the AC can cause you to go searching for a cure. The real cure is to keep cable feeds out of your system and your systems AC.
