Find a demo/used NHT Xd system (there are a couple on Audiogon right now), should be ~$2k or a bit less, and since it includes a power amp you can sell your current one for an even lower net cost.
The sound is, in a word, staggering. Unbelievably transparent, unmatchably accurate, and you'll have (subject to the room) dead-flat response down to 25Hz. Reviews had the Xd pegged as a contender punching well above its original $6k price. At $2k, well, I think it becomes a compelling purchase (and in fact I was so compelled myself :-) ).
If you want a more conventional system, the Dynaudio Focus 140 is very nice indeed and list for $2k new. Honestly though, to my ears at least, the Xd is so good that even something as nice as the Dynaudio doesn't come even remotely close.
