Good match for Anthem AVM 30

I am making my first leap into separates and could use a little advice. I found a good deal on an Anthem AVM 30 and am looking for a good 5 channel match (prefer a good used piece from an Agoner). The obvious choice would be an Anthem A5, but I am also interested in the Parasound A51, the Rotel 1095, and possibly an ATI amp. It seems like the Rotel and ATI would offer the best bang for the buck, but I am sure some would say that I would be better off getting the Parasound or Anthem. Any advice would be greatly appreciated. My setup (might help things) is as follows: the Anthem AVM 30, Polk LS 90 towers (early 90's product), Polk CS 350, and Polk M3 Monitors. No sub at this time but I believe I am going to pull the trigger on a SVS sub (PB 12-Plus) or a REL R305 or R505 (any opinions on subs would help as well). Video is Sony SRXD 55" DLP and Sharp Aquos BD HP20 (blueray). Straight plug n play (HDMI) from blueray to monitor. No HDMI upgrade work on the AVM 30 yet. The room is 20x22x8, two doors and no open air spaces. Again, any helpful advice would be greatly appreciated.
