I know it's an issue with tvs, but what about audio equipment? I've been fighting a ground loop, and I may need to move my sub next to my equipment rack. Is this an issue? (No VCR in the rack, by the way. I know THAT would be an issue. :lol)

Also, unrelated to the 950, is it a problem if one of my mains is partially in front of my subwoofer driver? The speaker is on a spiked, sand-filled stand, so I'm not sure the vibrations would transfer.
