In a few months, I might pull the trigger on a Denon 2805 or 3805, depending on the price and some other factors. I got to wondering: a few years ago we had 5.1, then 6.1, and now 7.1 is the norm on most receivers. We have new versions of DD and DTS. That sort of stuff. As I don't have the money, room, or reason to go with anything more than 5.1, I am not concerned with that. However, what will be the next big thing in receivers and surround sound? I figure it will not be adding more speakers, but better processing and new, better formats? Is there anything on the horizon that I should look for, or should I buy a 3805 for my 90% stereo listening? Just thinking out loud. At a certain point, people cannot put up any more speakers (unless that have a big room and are doing custom work with mixing multiple channels and such) and we will just be working with 7.1 or whatever.
