Best bookshelf speaker?


I am considering several bookshelf speakers, including Focal Sopra 1, Focal Kanta 1, Kef Reference 1, and the Bowers and Wilkins 705 S2 signatures. I would consider others as well.  Detail, clarity, and imaging are important to me. Any recommendations?

Go with lsa speakers...they were voiced to match the joseph pulsars at one third the price. They won a big award this year, the finish is sensational. 
You can get 20 suggestions and still not have an idea. Dusty channel isoand audio designed lsa for wally...dusty is involved with very high end VON Schweik speakers. The lsa mirror the josephs...id run and get a pair.

Impressive standmount. Completely disappear, full spectrum sounding and sounds more "floorstand" than most floorstanding speakers I had heard. Still cannot understand how that's possible. The only drawback is their price.
