I am at present running a Yamaha 5540 with Keff eggs. I am looking at upgrading the amp, possibly to a Denon 3803 and getting some 'proper' stereo speakers. Would it be possible to set the speakers so, when in Movie mode I use the stereo speakers instead of a front, with the keff's, which are positioned at the top corner of each room, for effects. I could then use my extra egg for centre rear surround. I know it sounds complicated, but unfortunately I'm only 'allowed' so many speakers in our living room!
