Cool that's my wonder as well. How awesome could SACD\concert footage be? Would you daisy one of the channels? Isn't 13.2 the highest Denon/Marantz processing?
Isn't the proper placement plus Phantom center strategies enough for the 1100s center already?
Sorry so many questions. Sounds like a lot of fun. Complete massive emersion. At a still in reality price. As opposed to some of the equipment you'd go too see at say Axpona and other shows.
