I'm sold for now on giving up XLR and getting more cost effective yet sonically high(er) performing AVR instead of pre\/pro. I just ordered a 3700 and should have it in a few days. :p\n\nThanks again for everyone's participation. I would still like to explorer remedying my ground loops though. So I will be unhooking the FM antenna and seeing what shakes out and report back what I learn.
