If I may ask. why did you get rid of your 4802? I also have one. my speakers are 4 Ohms and I have a large room and like to listen pretty loud so I just upgraded my power. up front for my L&R I picked up an Accuphase amp. for my center channel I got a Hafler thats bridged to mono. I got both of those GREAT amps on Ebay for far less then $3500.00 and they sound very nice.
