-> Hi Bob!
->
-> Audio systems must be grounded at one location and one only, which is
-> why I hate grounded electrical. The thing is, there is a ground on
-> the audio too which causes instant ground loop when using grounded
-> electrical outlets. Also, the ground reference should be at the
-> lowest signal (such as mike mixers and turntables, et al).
-> Everything else should be "star" grounded to that location and then
-> everything taken to the electrical ground, which is only for safety
-> reasons, otherwise, grounding is not really necessary. Another thing
-> I try to insure is that all of the electrical is from the same phase
-> so that if there is a problem, you don't end up with a 220 volt
-> potential across your equipment.

Yep, I ran 3 10-2 romexes to feed my system - and all are on the same
"side" of the neutral.  I also checked the current draw in each branch
and picked the one with the least motors, compressors, etc. just for
good measure :)
