Speaker suggestions?

I'd welcome suggestions for speakers to audition. I presently use ADS L710s with an Adcom 535 amp and an Adcom 555 preamp. My source is a Teac cd changer. My room is 14x22x8(high) with hardwood floors but a fair amount of stuffed furniture. My listening position is about 7-8 feet from the speakers. I almost never listen at loud levels (no more than 9 o'clock on the volume dial.) Due to spouse and furniture, the speakers must be placed within 6" of one 14' wall, one on each side of a 8' window (i.e., basically against the wall, and within 2-3' of the sidewalls). I listen to a lot of solo piano music, small group jazz, female vocals, some chamber classical, and some choral. With this equipment and my space limitations, I think I need speakers that are "forgiving." The kind of improvement I'd most like is more better quality piano and less of the "boxiness" that I often hear. Any suggestions for speakers for $2,000 or less, new or used (and that would have to include stands for monitors). Thanks in advance.
