Normally, I would say Magnepan (for example 1.6QR), but with a smaller room and with that amp (although I really love Creek's, they really don't like Maggies...). I doubt you could make them sound good due to room size.
Vandersteens are always a good choice, especially the 2CE Signatures. Easily within your price range, and much below if you look at used. Not too difficult to on the amp either.
