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.
