Thanks again, Al. I do understand the basic theory of ground loop as it applies to mains power...in a muli-component system there can only be one grounded component. But thanks for explaining the IC grounding issues.
I was wondering if AC from digital device could be coming back down the PC into the power strip.
Yes, I did put unit with cheater plug back into same receptacle of pwr strip. I also tried CDP plugged into wall on different breaker and it sounded harsh.
