Get a pair of the older KLH 5's in good condition. They use a different midrange configuration and despite audiophile angst about cross-firing mids, the image very well and very precisely. Would make an interesting comparison, and with some careful shopping the older version can be had for about $250-350 per pair.
Just to drive the point home, my "old" pair have replaced my Thiel 3.5's in my main system, and I don't miss a thing.
