I'm having a similar problem John, so frustrating. See my post (link below). The Emotiva didn't help my amp. Back to the drawing boards. Think I'll see if i can try out a line conditioner at a local dealer. I don't want to drop a few grand on a fancy power conditioner just to find out that it's just like the Emotiva. Fortunately, the Emotiva has a fantastic return policy!
One question for your situation - any hum/buzz coming out of the speakers or just the amp? Mine's just the amp - speakers remain silent.
Good luck.
