I am currently demoing at home the yamaha 5790 with 60's the 150 and 2 qs8 and an old sub and 2 polk monitor in the back It sounds terrific. I will also be trying the the elite 54 and 56. I heard the 55 and the Denon 3805 I preferred the Elite. Much cleaner sounding but both had great DSP on the dvd's. (This was at the HIfi store with a 5.1 M&K setup)
