optical connection yes, coaxial no, since coax still uses a ground which would
link the two grounds together. I'd also suggest using a smaller ground wire,
14 or 16, so that if there is a ground fault it will want to travel down the
components natural ground instead of flowing through the other component. As
well, if you receiver does not have a ground prong then definitely ground it
manually with a 12g to the wall socket ground!
