Had similar results of nonoise. Was previously plugging amps and source gear into Transparent conditioners plugged into 15Amp receptacles. My local Dealer recommended I install dedicated 20amp outlets, assuming you have the space in your primary fuse box. I believe the contractor charged me $300 for the work.
Now the Amps are plugged directly into the dedicated 20Amp outlets and the 2 conditioners in the other two for all source components. The difference was significant.
