Ok I will try replacing all powercords when they arrive this friday.
However, I am not the only one on the planet who has speaker buzz. There are reports of other brands of ac regenerators, in a system with efficient speakers, and certain amplifiers, that will cause audible speaker buzz.
My best guess is, this ac regenerator puts out a magnetic signature that is somehow amplified by large steel racks and makes its way into the speakers. My new turntable reveals a tonearm/mm cartridge needs 1.5 feet distance to the ac regenerator or buzz occurs.
If I had a dedcated room, the ac regenerator could be located several feet away such that it causes no buzz. But I a forced to put all my equipment against the wall.
The lowest noise location I could find was placing the ac regenerator underneath one of the smaller steel amp racks.
