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?

I'm with fuzztone if your budget goes to that point.  Also look at Joseph Audio Pulsar and Reynaud Voce Grande which comes with integrated stands.
Lots of good options you have so far.  As mentioned above, for sure add the Joseph Audio Pulsar2 to your list.

I have the KEF Reference 1 in my main system and they are amazing.  I have turned my preamp up to full volume and there is no distortion.  Very detailed but not "bright", they are easy to listen to and throw a huge soundstage and have great imaging.  I have (and love) Harbeth P3ESR, but they are not in the same league as the Ref 1.  No experience with the other speakers mentioned.
