The solution in this case was
to fit ferrite rings/loops at either end of his speaker leads and he
never heard me again.

If you are going to run long speaker leads it may pay you to invest in a
few ferrite rings/loops and save yourself a lot of headaches down the
road. They are readily available from the likes of Radio Shack at
reasonable prices.

That's a great tip, Larry. Would you mind detailing how these ferrite rings
are installed? In my case, consider that I'd have my wire running in EMT
for one set of speakers, and in PVC sch. 40 plastic in the other. Each
set terminates in a steel box, and the runs would be made of stranded 10
gage THHN wire, color coded to insure proper phasing. I'd like to make
sure we don't get any noise that isn't a part of the music!

Thanks---
