I posted in error that the 2808ci uses the Burr Brown PCM1796. I actually uses the Texas Instruments
Burr Brown DSD-1608.
I've managed to tweak the 2808ci so that it sounds close to how I had my old 3805 setup. The Audissey MultEQ XT did not do a very good job of setting the subwoofer and center channel levels. I think the surround processing is a little better on the 2808 and my favorite movie/scene of choice, LOTR: Bridge of Khazad-dûm, the arrows seemed to come alive. That may be the Audissey MultEQ earning it's room and board.
I still miss my 3805 and will probably look at ditching the 2808ci and grabbing a 3808ci if I can get a good price selling/buying each.
