How to eliminate popping noises from ac supply?

Hello, I have been recently experiencing a raft of popping sounds through my loudspeakers. I recently rearranged all my plug-ins in my Furutech eTP 80 to ensure all components were plugged into appropriate receptacles, digital into filtered side, amps into non-filtered side, and now I have these popping noises in my system. Any time something is switched on, light switch, etc., the noise occurs. I have a dedicated 20 amp circuit to my system. Any ideas as to how to cure this problem? Thanks for any help that can be given, Dan

No chance that a refrigerator is on the same circuit?

No, not on the same circuit, although they would share a common ground in the panel. These noises are coming from light switches and other sources, I have even heard it when something switches on in my cd player! This has me stumped. Thanks for your reply, Dan

What happens if you plug your equipment directly into the wall outlet/s? Removing the Furutech ETP 80 from the equations totally. Still have the popping noise? Maybe the problem is the Furutech.

I actually used to have serious problems with this before I got the Furutech. I've not had an issue with the Furutech since I got it a couple of years ago. I very much doubt that's the problem, but if all else fails, that's something to try. Thanks for your reply, Dan
