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!
