Coda was the first that came to mind, and there’s a nice CSX available here now in your price range that’d likely drive anything you can throw at it.

If you think you could get by with “only” 500Wpc into 2Ohms this SMcAudio DNA 1 is a sweet sounding amp and is probably negotiable at $2200 so would save you some $$$. Plus if you like what you hear you could send it to them for all their latest upgrades for even more and likely still be under your budget.

Best of luck.
