I picked up my used Goldenear Triton Ones for $3000. Shouldn't be hard to find a price around there. Pretty nice speakers, I'd say. I have them connected to Bel Canto amps but you don't need 600 wpc. For your budget you might be able to find used Triton One.r or Reference speakers in the used market.
Note that these speakers have really nice sound stage and imaging, but only when set up right- plenty of room from the wall and toed in.
