Alons IVs or Vs. The Vs are a step up from the IVs in all but the lowest of bass, easier to drive, and smaller. I drive my IVs with a AKSA 100. There is a pair of black Vs on audiogon for $1500. Rosewood is generally more expensive, but is beautiful. The IVs are less. If you value 'truth of timbre' and soundstaging/imaging, you'll fall in love with these speaks. You need space behind the floorstanders, 3', and must triwire with Black Orpheus, or similar.
I've had the IVs for 11+yrs, and while I've upgraded all other components, I've never felt the urge to upgrade my speakers.

How large a room do you have? If a smaller room, consider a Arum Cantus Leisure 2SE bookshelf speakers, stands required. I'd never been impressed by these until I heard them driven by the AKSA N+ and Tara Phase II Return speaker cable. Truly a wonderful combo. Dunno why. New, they're in your price range, and used, should be substantially cheaper.
