I suspect it will do about what's expected from Denon - warmth, good dynamics and weight, slightly shy top end (better air and extension on others), and just descent with analog sources. The Audyssey and HD codecs, of course, will be a plus, and carry the sound quality a bit.
I guess: 94/100 for HD movies, 91/100 for older digital movies, and 83/100 for analog sources. That's my "Professional" educated guess! - lol.
Actually, would like to hear the thing, and read a review or two myself.
As for anthem, pretty nice digital av pre/pro's from what I've heard. Although I've heard better dynamics from other AV pre's and better refinement (of course) from better two channel pre's for analog sourcing - as predictable. Still, nice stuff. (minus the Audyssey)
How about the Sim Audio pre? They've made some great sounding gear, and it has Audyssey! Anyone hear this?
