Best skiinny floorstanders

After 10 years with a pair of Martin Logan Ethos speakers, I'm considering moving back to boxes, box speakers that is.   I'd like to avoid big obtrusive box speakers and am considering some skinny ones in the $8-12k range like the:
Devore Fidelity Super Nines
Boenicke w11s
and...
.... other suggestions

The room - is around 18 by 30, parts with a low ceiling, carpeted, and the wall behind the speakers is books. Serves as gym in the early am when my wife pulls out the rowing machine and turns the tunes up loud, play room for the grandkids in the afternoon and listening room for me in the evenings.

Currently running all tubes but I'm open to changing that up too.
Taste in music - eclectic.

Thanks in advance!
