Hey Stereomaniac,
You mention your listening distance, but it also matters along which wall the speakers are placed and how far from the wall they can be placed. Your listening distance is definitely near field, so large woofers (over 6 1/2")generally won't work. Rear firing ports or tweeters may be a problem if placed too close to rear wall. Room damping/liveliness are also signifcant variables.
Where do you live? If you are anywhere near Milwaukee, I can let you try out a pair of ProAc Response 1.5 (gorgeous, and for sale on audiogon), or a pair of Red Rose R3, but I'm not letting go of those (at least not at this time). Both are winners in most smaller spaces: they are versatile with ability to play delicately or to really rock.
