Vandersteen 7 would be the best I know of and have heard, although those are a bit above your price limit unless you get them used. For new, Verity Amadis or Vandersteen 5A Carbon. I have the Verity Amadis in one of my systems and they are superb for symphonic and other large scale music. But the Vandersteen 7 plays in another league entirely.
Good luck!
