I have a Micromega M-150 in on trade. Unbelievable amp but I think some of the reccos above are not taking into account the sound profile of the amp with those speakers. I can think of one or two that would make me want to take an ice pick to my ears if they were combined.
You will never find Geometry's from Wilson Benesch in that price range unless used but they would be splendid. They start at $10K new.
Sonus Faber would be brilliant and would work really well with that amp.
A pair of used Joseph Audio Pulsars would be brilliant. I make something similar but honestly need to work on the crossover before I would sell it to you. That Pulsar is very, very well made with very hard to use drivers.
Acoustic Zen Adagio Jrs might be a really good choice. The tweeter is amazing and your amp would bring the most out in them. I love the Adagio's.
Finally, I make a speaker that might work really well for you. The Verdant Nightshade 1. I have a demo pair for $6000. I know a little above your budget but the speaker has a very flat frequency response and tremendous detail. I was just listening to it with the Micromega M-ONE 150 and was shocked at how true they sounded. I normally run tube gear and the resulting sound is a hair warm. 30 Day return policy still applies.
