Everyone, thank you for the replies, keep em coming.
What I am trying to avoid is, as Sub suggested, a compromising adapter in the cords. Now I know that putting a ground switch in does exist, I can look into it. For breaking off the ground prong, I don't know about that yet, especially after spending a few hundred$ on cords. For any cord gurus out there, which is better, undo the ground wire at the prongs or at the IEC, then heatshrink the wire? Or does it make no differance? I really want nothing between the cords and the Porter outlets. Right now I have a filter in the rca's from the CATV box (digital) to the front ch. amp. The hum went down a lot, but not as much as a cheater plug. Maybe lifting the ground from that rca input or cable would work? Any other suggestions or comments?
FWIW, this is what happens when you you mix a great stereo system with home theater, problems, ground loops and frustrations.
Thanks again and I will post any changes, hopefully soon, when they happen.
