This is a real serious stuff for the real home theatre enthusiasts. Compared to the highly acclaimed Denon AVR-X3800H, this one is more powerful (120W vs 105W per ch), has Dirac Live which is the best Calibration software you can have at the moment. IMAX enhanced and THX certification are just icing on the cake.
I had my eyes set on this one over Xmas but I could not get it at this price, I was offered it's clone, the Pioneer VSX-LX505. I have to say the sound quality is on a completely different level compared to my old Yamaha V6A. The Onkyo is much better in that it has individual cross over setting rather than global on the Pioneer. In the US it is hard to even get one in stock.
Alternatively, Audio Junction also has the TX-NR7100 for $1479 (rrp $2299), which is almost identical but with less power (100W per ch) and no preouts, so limited to 9.2, which is adequate for most people with smallish medium sized room. That is the cheapest I can see for 9.2 ch AVR.

Good deal. I am waiting for a good deal of RZ70 but haven't found any yet.
