I have not heard anything, but please give us your thoughts once you have used it for a bit. I am one of the few people around here who is hardly surprised that you like it over a Yamaha receiver, but that's just me.
I had a chance to audition this unit for a bit but ran into HDMI problems. I had about 1 second drops in audio/video during BR playback and gaming. I'm not trying to scare you or anything because I experienced this with the Onkyo 805 also. Both units were hooked to my PS3 so who knows. Maybe my PS3 is picky Seems to like Yamaha and Denon
Just to drop a few thoughts, I really liked the look of this unit. Very easy to setup and use. The sound was really good and had a warm, kinda laid back feel to it. Perfect for the type of Jazz I like to listen to. Unfortunately, due to the HDMI issues I really didn't get a chance to spend much time giving it a proper audition.
I'm sure your gonna be happy with this unit. As PS mentioned, we would love to hear your thoughts after you get a chance to spend some time with it.
