Best Speaker for classical music

For classical music the exact imaging of the soundstage and Hall acoustics are crucial. In my book that means omnidirectionals and simple cross overs: Shahinian, Duevel or open baffle Shindo, Ophelia, Auditorium23

+ 1 for omni directional with classical music.  Duevel Sirius, German Physiks Borderline, MBL.

Classical music is a far more demanding genre - from my point of view.

My desire that a system can reproduce accurate timbre ( not washed out as is all too common) far outweighs its other qualities, such as imaging, or collosal dynamics etc.

This possibly exaggerated desire for tonal colour leads me to believe I might have some form of chromesthesia (sound-color synesthesia).

Classical music especially, without good instrument timbres, is difficult for me to enjoy, whereas with rock I'd be looking for great dynamics or for pop it might be a great midrange.

Classical music with good timbral expression on the other hand becomes a joy. Especially piano and strings.

So I think it's a question of finding a speaker that excels at that quality that's most important to you.

All loudspeakers are not created equal, and few, if any, can do everything right.

Having said that, you wouldn't go far wrong with any of the BBC inspired designs out there. They're not always the first recommendation for rock (JBL/ Cerwin Vega?), but might fit the bill if strict neutrality in the vocal range is especially important.

If it's imagery and hall acoustics that you primarily want, then as was said previously, omni-directional designs might suit better.

So maybe even the distinction between classical and the rest might not be precise enough. It may depend upon just which aspect of classical you enjoy the most.

I've heard some Sonus Faber Amati Futura with expensive Accuphase and Luxman gear and they were excellent for orchestral music. The midrange in particular was stupendous in terms of natural timbres and realism.

Hmmm, I would lean to the Rockports, Vienna Acoustics, Magnepan 30, or Joseph Audio.  I have an admitted bias against Wilson and have listened to them many times.  I have only heard one system with Wilsons that I liked.  Similar issues with B&W.  The only advise I can give is to listen to some violin music to determine if you can live with the upper frequencies.
