I should have added what was in an earlier post: Each piece of equipment is 
tied to a #2 coper cable with (1/2" braid/shield) that runs along the back 
of the desk. The longest ground is the one from the amp which is about 12 
inches.  That #2 cable also runs back through that common bulkhead near the 
entrance.

These are the grounds, not the neutral.

The only common point is back in the 200 Amp panel at the entrance.
