You want XT32 with Sub EQ HT. Might as well get the most value, IMO. (If you decided to get Audyssey bass mgmt for TWO subs afterward*, then get ready to throw down at least $750, or more.) You have four choices:
Onkyo TX-NR3008
Onkyo PR-SC5508
Integra DTR-70.2
Denon AVR-4311CI
You can afford the first, cannot afford the second, probably cannot the third, and can perhaps swing the last if you throw down just about $100 more.
