Exactly right! U Wis EE prof R A Greiner published his research in a
classic AES Paper nearly 50 years ago! What he didn't know (or maybe
knew and didn't emphasize it) is that twisted pair is excellent at
rejecting differential mode RFI to power amps! The coupling mechanism is
via the feedback loop around the output stage, with rectification at the
stage where the feedback joins the signal chain.
