Yeah, I don't blame you. Those ATI pre-pros are more like ANALOG preamps than processors. If all you wanted were an analog 2.1 music setup, then the $600 ATP6700 would be great enough. But if you want a true processor (HDMI and all that), then it's better to get something else.
I would call Electronics Expo, Vanns, OneCall and see if they can sell you the Denon AVR-3312/3313 for $600/$800 respectively.
For pure 2.0/2.1 music, you don't need any Audyssey XT32 or any RC/EQ/DSP. You just need Pure Direct/ Direct modes. Actually, for 2.0/ 2.1 you probably don't even need an amp.
I use a Denon 3312 in my family room w/o any ext amps. The 3312 can drive my Philharmonic 3, Focal 826V, and Dynaudio X32 extremely well in Pure Direct 2.0/2.1. I actually let my AT2004 power the four Velodyne unpowered subs and let the Denon 3312 power the towers.
