Tim,
I have been following this thread with interest. I have two points:
1. Did you say that you had confirmed that your dedicated audio circuit is not on the same hot buss as the furnace?
If those two circuits are still on the same hot buss, I would be interested if moving one of them to the other buss solves the problem.
2. A simple passive power conditioner may also solve the probem. In my small cabin, one curcuit feeds my audio system as well as a laptop computer (and refridgerator). The laptop was putting noise on the line simply by being plugged in, and much worse noise when its processors were working.
A PS Audio Duet power conditioner eliminated the noise. I first plugged the laptop alone into the Duet and that worked perfectly. I then plugged the amps alone into the Duet and that worked perfectly as well. I run it that way because I can then plug the CD player/DAC into the Duet's other isolated outet. This arrangement isolates the CD player from the amps and allows for the filtering of noise from other things on the circuit (e.g. fridge).
Regards,
Charlie
