Thanks everyone for all the info. I've narrowed my search to the Denon 1610 or the Pioneer 919. I'm still pouring over Batpig's very generous info on Audyssey and comparing it to info about the Pioneer's MCACC. I have noted that MCACC does not include the sub in its automated setup, but it does seem to allow for more manual tweaking. On the other hand I like that the Denon includes the sub. I have a very live room and I feel there is a lack of continuity between my speakers and the sub.
Question: will the Denon be able to power my speakers? Whenever I see it in stores it is displayed or bundled with pretty small satellite systems. My front mains are JBL S36II with maximum rated power of 150w. My satellites are rated at 10-100w. I never come close to using the full power of the speakers. I'm not looking to blast out the neighbors, but I do want to be certain the receiver is appropriate for the speakers.
