As suggested earlier, prearrange demos with the dealer(s) and get to a city. I'd put together a list of speakers you'd like to demo first, perhaps drawing upon some of the suggestions here.
I'm in the same boat as far as having limited lines I can audition in shops close to my home. That said, after hearing Wilson, Sonus Faber, Fyne, Atohm, B&W, Focal, Triangle, and a few others, I plan to soon upgrade to PMC. When I heard them at my local dealer, they delivered everything I had been looking for: imaging and instrument separation like I'd never heard before in a floor-standing speaker, deep and textured bass, sweet and natural sounding midrange (especially vocals), and clean, incisive highs, The PMC Twenty5.24i and Twenty5.26i are worth putting on your list. Others I haven't heard but would like to are Borresen and Gershman (their Studio xDb speakers are sort of in your price range at $12k list).
