Ground Loop?

Do your wattgate receptacles have an isolated ground? If so, check the specs. Call their tech support. Most, if not all, isolated ground receptacles will require an insulated ground wire. If this is the case and you are using standard Romex, your ground is compromised. 

Thanks for the info. When the outlets were installed, I used in wall 20 gage AQ power wires. I've lifted the ground on both and individually with adapters. I even had the 350P or the JC3 Jr hooked up to a regular outlet, 2 completely different lines and lifted the ground on 1 or both in different configurations. 1 using the dedicated line and a standard wall outlet So, it's not the outlets. Still there, but again when I reach back on the JC3 Jr and when I touch the loading pot and only the pot it goes away. When I do touch the pot, the noise slowly fades away. I've been in touch with David and Jason at Parasound via email, and they stopped communicating with me and won't answer any questions or offer any kind of help.

On a 15A line? Are you in the US? That isn't even close to code where I live.

That also sounds problematic.

Do you have any other metal to metal contact going on?  Like via your shelf?

One other thing to check is that you have a good neutral.  Use a multimeter to test from Neutral to Ground.  Should see no more than a couple of volts.
