He did...2k. and you're way out of his league.

The Parasound A23+ is in your price range. Damping factor >800. Class A/AB 160w@8ohms. 

Bryston 7BSSTs  are perfect for low bass control. I use them as my sub amps and love them. 800 watts into 1-4 ohms. Figure 4-5K for the mint ones with lots of warranty left. 

Adcom 565 mono's can be had at this price point
