I've got my new speaker wiring run for Front L/R/C, and also Rear L/R/C, along with 2 side channels. Now I'm having a tough time finding a mid-range receiver to power this potential. Seems the Denon 3802 has A/B rear channels (this would power the L/R rears and L/R sides), along with a "Rear Back" channel that can be setup as a rear Center channel. With other receivers, it appears like 7.1 is the "processing du jour" with rear/side channels only (no rear center). Can this be done with the Denon 3802 (or any other comparable receiver) and is it worth it ? I still have to purchase speakers for the rear center and side channels. The L/R rears will be Energy direct radiators, but I'm contemplating Mirage omnipolars for the L/R side channels. Since the room is 25x25 with the "sweet spot" almost directly in the center, am I crazy for attempting this ? Any comments are appreciated (except "get therapy" - which has already been recommended by my wife).
