I you're willing to buy used, I'd suggest a few possibilities.
1) Green Mountain Europas- Marble enclosure, 1st order x-overs. Very good reviews, usually around $600 or a bit less on Agon.
2) Monitor Audio GR10's- Again, often available under $600 on Agon now that the GR line has been replaced by the GS line. I'd put them against any bookshelves I've personally heard under $2k (new). JMOHO, though- and I'm a big MA fanboy.
3) Onix Ref 1- I had a pair, and while I couldn't live with them long term they had many virtues. For one thing, they image as well as any speaker I've ever heard at any price. And they have a very nice midrange. They also exhibit build quality that betters most speakers I've seen under $2k. On the minus side I found them a bit "tipped up" or bright, but in your room with your electronics and more importantly, your own tastes, they might be just right.
4) Norh SM 6.1- They are synthetic marble drum shaped speakers. I will admit right up front I've never heard them but they have fantastic word of mouth from a dozen guys I trust. On Agon it can be a crapshoot- sometimes none come up for sale for several months, the next month their might be several.
