Advice needed: B&W 704 vs. Sonus Faber Concerto

[yoellax]

My wife and I listen exclusively to classical music. We are looking to purchase a new system, and we've been listening to a lot of different speakers. We're looking to spend around US$2000 for two speakers.

After listening to many different speakers, we have narrowed it down to two possibilities: We like the B&W 704 and the Sonus Faber Concerto. Of course the former is a floor-standing speaker, while the latter is a bookshelf speaker.

We've tested both speakers with a variety of different recordings (piano, voice, orchestral) and actually liked the Sonus Faber better because of the warmth of the sound. Our concern is that the bookshelf speaker may not fill our living room, which measures 30' by 15', with ceilings going up to 14'. The B&W has more to offer in the bass range and may be a better option.

I would appreciate any comments on either of these two speakers which may help us solve the conundrum.

BTW, our third-best was the JM Lab 714S, which comes in around $1500 for the pair, but it was dominated by the B&W 704 more or less clearly along every dimension.
