I have a pair of Air Tight AL-05 monitors which I run with the Air Tight 300 B (30th Anniversary) amp. Just unbelievable. Only a 4" driver, but out of this world clarity, coherence, sound stage, blah, blah. Very reasonable if you can find them. I paid 1300 used, new I think they are only 2500.00. I recently added a low powered REL sub, just because I could, but they really don't need it.
My two cents, but I do have three systems, a lot of experience. I also run ESL 57's (refurbished by Wayne Piquet, Quads Unlimited) on a Air Tight KT88 amp, (in the same room) and it's kind of a toss up, both are extremely good.
