Ed,

Please remember that I measured this effect, it is not something I dreamed up. It is possible that with ordinary RFI or noises, that this is not a factor. I measured this on spikes and surges in the context of a surge protector circuit. A lot of what might occur is going to be due to use of inexpensive CM chokes, not those that can actually handle decent amounts of differential current (the spec to look for), and may be a moot point if MOV's or other limiting devices are not a part of the circuit.

As I related, I had enough surge capability to pop 40 W light bulbs, and had to use heroic steps to isolate my experiments from neighboring AC lines, or I would reset or shutdown other peoples computers.
In order to complete and finish the design work they had to install a dedicated line for me.

At the time, my primary concern was to design and build the best surge/spike protector available, at a reasonable cost. AC line filtering was a secondary goal, but one which I wanted to acheive without compromise for audio components. The results are embodied in the circuit I make available as the DIY AC Power Line FIlter and Surge Protector.

All I can suggest, is build one, try it, and see if it doesn't help out the sound of your system, as so many others have reported.
