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?

The Watkins Gen4 is one I’ve been tempted to do a home trial on. Recipient of The Absolute Sound’s 2020, 2019 & 2018 Editors’ Choice Awards and their 2017 Golden Ear Award, and the price isn’t too high. $2500 iirc.

" Watkins Stereo Gen Four:
Bill Watkins has been perfecting the compact two-way since the early 1980s, and this is by far his best effort. Mating a 6.5″ Peerless woofer with a 1″ dome tweeter, the Gen Four’s bass extension and control are unheard of in such a small package. Unusually, the woofer is run without a low-pass filter, perhaps contributing to the imaging prowess and transient speed, which are spectacular for any speaker, especially one at this price."

Are you going to stand mount them, or put them on an actual bookshelf against the wall?
They will be stand mounted. I will be driving them for now with an Anthem STR integrated amp.
