For classical orchestral and choral music, I would suggest you make a real effort to audition Shahinian Hawks or Diapasons. They are designed by their creator to model as closely as possible the sound of an orchestra playing in a concert hall. They provide an extremely convincing spacial and timbral recreation of that sound. In addition, they boast very dynamic, concussive bass, an enormous sound field, more sense of 3-d ambience than I have ever heard outside reality, and a string sound that is palpably rich, realistic, and velvety.
Very importantly, they will play very loud without strain or tonal variation. I can listen in my 2200 cubic foot room to Mahler's Eighth at close to actual live-concert-level volume (peaks of 108db) and the sound is as good, clean, undistorted, and easy on the ears as at 80 db. This takes a good amount of power and current though (I use 2 Plinius SA-100's).
The Shahinians are polydirectional above 250hz and use a transmission line woofer terminated with a passive radiator.
They do not do pintoipnt imaging. Of course, neither does the Berlin Philharmonic or Miles Davis. If you want razor sharp images, unlike the reality you hear live, these are definitely not for you.
There are no US distributors so these can be purchased only from the factory at about $12,000 for Hawks, $20,000 for Diapasons. A used pair of Hawks just sold for $3200 on Ebay.
If you listen primarily to large force classical music, or any acoustic music recorded well in a live space, Shahinian's top speakers (or even the Obelisk, at $6000) are very, very hard to beat.
