1. The receptacle neutral and hot wires were not reversed. I checked.
2. I switched the new Hubbell recep out for my old one (common 20 amp one). Hum was still there.
3. I bought a new and better power conditioner. Hum did not change.
4. I lifted the ground with a 3 to 2 prong adapter. Hum still there.
5. Parasound service mentioned channel 2 is closest to the toroidal transformer and thus may have the most affect on hum. This is true and I would up rearranging the hum out of my fronts but it still present in my rears now where i switched them. Still audible from my listening position.
Today I had a really weird thing happen. I was further trouble shooting and messing around. At some point the hum was almost "jumping" around. First I heard it in my Outlaw amp (runs my ceiling atmos channels). It sounded like it was coming from inside the amp itself. When I turned it off the hum jumped into my subwoofer. I don't know what I did but I just turned it all off and put it all back together. It went back to just hum in the 5 channels like it always was.... very confusing to me but suggests the issue is my system rather than parasound? @geof had mentioned this. I still have not tried removing the light dimmer from the line.
Parasound does not really have any more to add and did state they would check it for me. I have to ship it to them (which I pay) and they would ship it back free.
The dealer who sold it to me suggests I have to plug it into someone else's home's receptacle to see if anything changes. At 50+ lbs i'm not excited about this idea but i'd consider it......
