I think there is more value in the all channels driven figure now than ever before. I was listening to Radiohead in 5ch Stereo when reading this tread, and I can tell you that each was getting a workout. Same with a recent viewing of Master and Commander, where the sounds of the sea and cannon fire below decks seems to force all speakers to perform. I want all 105 of my watts available...dang it!

Query: If I bought a 2 ch separate amp for L/R, would that mean my Denon would delivery more watts before clipping to the remaining 3?
