Speaker Choice for a larger room

Hey all.

I'm going through change in my system again. Whilst I'm in the selling mode presently, and won't be buying for a little while, I would like to start to plan out future purchases.
The main area of concern is finding a speaker that will couple effectively with my room.
The dimensions are 28' X 45' and the cathedral ceiling goes up to 28'
I'm using Maggie 3.6's presently, but plan on changing things around.
My musical tastes are Jazz, classic rock, some blues, some classical most anything that isn't country or rap.
What I want from my system is:
Scale - large open soundstage, good width and depth
Imaging - precise placement of images but with emphasis on 3 dimensional realism
Palpability - the sense of presence and quality of the midrange.
Bass extension isn't of absolute importance, as long as I get a good sense of authority and impact in the lower registers.
I prefer a warmer sound with more bloom and midrange presence over a brighter more analytical sound.

On my list are:
Aerial 20T's
Sonus Faber Cremona
Avantgarde Duo's
Wilson Sophia's
Kharma 1.0's
Soundlab A1's

From the above, I've only heard Kharma's so I may be off target with my wish list of sonic attributes, though I have owned Sonus Fabers, a smaller model, and they seemed to do much of what I like best.
I'm flexible on amplification at this point, but would lean toward tubes, something around 200 watts, perhaps the Antique Sound Lab Hurricanes.
Source is and will remain digital.

What can you suggest that would take full advantage of the larger listening space, and would also be effective in a smaller space (I may move house in 6 months or so).

Would appreciate any insights. Budget wise, the 20T's are as high as I would go (used $12000 ish)

Thanks
