Question about Snell B with amps and preamps

My room is 15' x 21'. I'd like comments from people who have heard the Snell B with various amps and preamps (or integrateds). Base on your experience, can you recommend an amp and preamp for this speaker, such as the Plinius SA-250 mk IV, with classical music? Thanks in advance.
Is this a Model B or B Minor?
The Snell B, not B Minor. Thanks.

A good friend of mine has these with a Levinson 27.5, it's a great combo, I suspect the Plinius would also work well.
