Have to agree on Shahinian here. Given that Richard Shahinian spent probably half of his life in concert halls and actually conducted orchestras if I'm not mistaken, if these speakers can do one thing it's classical. Altough this is at least 6 years ago, I have heard impressive presentations with both Hawk and Diapason (with Croft and Jadis amps).
One that would have to leap to one's mind, if you can still find it: Bösendorfer, the VC7 may just fit into your budget. The bad news, when Yamaha took over Bösendorfer they decided against continuing the speakers production. The good news: mastermind Hans Deutsch is now building basically the same speakers with piano builders Joseph Brodmann Group (itself headed by former Bösendorfer people). So watch out for the Brodmann brand too!
