You have a good start. The limiting factor now seems to be the physical connections at all the AC outlets between the breaker and your system outlet. When I lived in a townhouse, I had an electrician remake all these connections so that none were using the push-ins on the back of the outlets. We bolted the bare copper wire to the side screws and there was an immediate improvement. I also plugged nothing else into the outlets on the same breaker. I have also discovered that AC dimmers used on halogen lamps and ceiling fans anywhere in the house are a huge source of noise, even when off.
