I heard a $20,000 pair of InnerSound electrostatic/dynamic hybrids that would do the trick. Incredible dynamics, detailed, and able to play really loud. It is also relatively compact in size (at least compared to SoundLabs). As someone noted above, it does not have wide dispersion so the ideal listening space is only one person wide.
Another great choice is the SoundLAb electrostatics, but they too might be a bit out of the $15,000 range.
A dynamic speaker I heard at a show that impressed me was the Gershman GAP828. It is reasonably lively and musical and throws a quite large stage.
I like my speaker system (S.A.P. J2001-twin), which is a very efficient (99db/w) dynamic system with a horn midrange. But, it is extremely hard to find, and again, a bit outside of your stated range ($22,000). But, on the plus side, just about anything will drive this speaker.
