I believe my Integra DHC-80.3 specs say it puts out more voltage through the balanced connections, but I don't know if that would make a difference. As far as my limited (mis)understanding of balanced goes is that there's a third connection that is the shield, and that it might help in preventing ground loop issues (and rejecting RF noise, thank you). .. I already had very quiet front L&Rs, with only the slightest buzz in the rears ¢er you could only hear if you put your ear right up to the speakers when the volume was way up with nothing playing. I was running center & rears from a separate amp Adcom GFA-2535 4x60w. My 5 channel Adcom GFA 7000 was down to 2 working channels until yesterday when another one died a horrible sounding death. Thus, here I am awaiting my deliveries. THANKS to everyone for the responses!
I'm glad the failed amp channel distortion didn't fry my new KEFs, It's been an EXPENSIVE year so far and I was already poor!
