RE: Copper

I would definitely NOT want any magnetic field to enter the chassis. Ever hold a nail to a magnet? You can pick up small steel objects significantly farther away since the ferrous nail actually carries the magnetic field and exerts that field farther away. You DON'T want stray magnetic fields around actual audio circuits.

I believe your proposed layout is how I would do it. Just ground the copper foil sheets. The sonic difference is subtle but audible. I believe the induce charge eventually builds up and it seems to make things sound "quicker" when it is grounded: not immediately but at least in long term listening, which is why I believe a charge can build up.

YMMV
