Just looking at bookshelf speakers, there are a lot of good options in that price range both active and passive. Neumann KH120 MKII is an excellent choice and gets you well within the budget.
Genelec 8030c is another easy rec although not as much of a no-brainer as it used to be. (I have these, quite happy)
Audio First Fidelia is well within the budget and really good.
Ascend Acoustics Sierra LX also great and well within the price range.
And of course if you can catch them when they are in stock, the Ascilab range is mostly within your budget also, and they are in many ways some of the best-measuring speakers ever seen.
Just a few off the top of my head, and only bookshelves. If you are open to floorstanders there are even more possibilities, doubly so if you are willing to look for secondhand stuff.
If you can give more detail about your must haves and dislikes, room, goals, etc we could give more specific recs.

e: Everything I mentioned has good objective performance according to the idea that the speaker should play the music without adding or subtracting anything.
@Davey makes a good point though. At some point it's a matter of taste. The best way to decide is to hear speakers in person. I would recommend hearing some that are really "neutral" like these before spending the money, but that doesn't mean it's wrong to like something else.
