Who makes an AVR with bass mgmt. & Q-control...

Controlling room reflections and anamolies is a very cool idea and I'm sure more AVR builders will begin to incorporate this technology into their products. Anyone have any insight into this technology and who utilizes it beside Rives?
All have bass management. Many (Denon, Yamaha, Pioneer, Sherwood, etc.) have various types of room correction and/or EQ.

Kal, not a fan of Yamaha... between the Sherwood, Denon and Pioneer, which one has the best blend between audio reproduction and excellent video signal processing? The Sherwood looks cost effective, but I've always associated the Sherwood name with class C or B equipment. Any thoughts?
