A speaker that works well close to side walls, provided you can give it breathing room behind, is the Sound Lab Millennium-2, a full-range electrostatic. The larger Millennium-1 won't give you quite as wide a soundstage in your room, since its greater width means you can't spread them quite a far apart. The Sound Labs excel at timbre, inner harmonic richness, and nuance. The M-2's retail for twelve grand with options, which would give you plenty left over to get a really nice amplifier.
In a more conventional speaker, you might want to look into the Piega's recommended by Jtinn.
Best of luck in your quest!
