Best floorstanders for classical?

I saw this question elsewhere and it resonates with me too: I would love to own a pair of Quad 988/989, possibly with sub(s), but space considerations absolutely disallow it. Which small foot-print floorstander would bring me closest to that sound? If you can't or don't wish to use the Quads as reference, which one would be best in your opinion, for classical music in a medium room?

My buying budget is <$3k used, should also work with a good ss 60w/ch amp, but listening-now and planning-for-future budget is unlimited!
