I recently added a Parasound amp to my HT and as soon as I hooked it up I got a ground loop hum from my digital cable tv. My cable company is coming out sunday, hopefully they will be able to fix it. Anyway, I just wanted to know why are amps so sensitive to ground loop problems and receivers aren't? I've had three different types of receivers and have never had a problem with ground loop hum. Just curious.
