Speaker Dilemma--A Good One to Have but Confused


I now have a dedicated 3rd floor music room.  It's large--about 18' long by 14' wide with 10' ceilings.

Currently, I have PSB Imagine T2s run in summer by a Creek EVO 100A integrated and in winter by a Primaluna Dialogue HP Premium integrated.  I'm looking to move the T2s downstairs to the living room, which means I need a different speaker for the 3rd floor music room.  

I listen to all sorts of music in equal portions jazz, rock, folk/blues.  I'm thinking that I need a speaker with 90 dB efficiency or more to accommodate the Primaluna.  I can run the Primaluna with KT150s to put out about 85w of tight tube power.  Here's my shortlist below.  I need your thoughts and additions/revisions to it.

Tannoy Cheviot
PSB Imagine T3
Focals
Klipsch Cornwall

I bet you're using maybe 3 to 10 watts when listening to anything, regardless of the relative efficiency issues. I use a 12 or so WPC little tube amp with Klipsch Heresy IIIs (hard to beat the 99db efficiency these have, but subs are important since the Heresy III goes to only 58 hz or so) and it's clear and plenty loud if need be...efficient speakers do more than just play louder, they seem to dig a little deeper into the music.
The Focal Aria is a richer speaker than the PSB in virtually every regard. HR reviewed both and I personally feel his reviews on the PSB, Focal 936, and other competitive speakers reflect the reality. I love my 936’s. Huge, deep, detailed soundstage. Very smooth sound. Startling dynamics. Deep, well defined bass. Just a damn good speaker for $4k.

And I agree with Wolf. I'm not using half of what my 32 watts F5 will deliver. 
Thank you everyone! I’ve been researching your re ommendatons. Each of you has added something helpful.  

The explanation on Focal’s signature sound versus PSBs Is enlightening. 

When I get to work, I’m going to list my equipment and options for the group because I’m stuck in analysis paralysis!
