Tubes or S.S. for Thiel CS 2.4?


Hi all.....I was hoping you all could give your opinions about a seeking out a new amplifier for the Thiel CS 2.4s. I'm currently building a house which will have a dedicated library/listening room about 18 X 23 feet. It will have hardwood floors, but plenty of bookcases/furniture. I currently am using a Classe CA-100 in a smallish room, and they sound great. I don't listen very loud, but this will be a new, larger room and the one component I would like to move on to is a new amplifier.
My thoughts/questions were concerning power output of a lower wattage tube amp vs. a larger solid state amp. Ideas running around in my head were amps in the price ranges of the McIntosh MC 352/MC 401, Classe CA-300, etc etc while tube amps I've thought about inc. those like BAT VK 75se, McIntosh MC275 etc.. in those power/price ranges.

What do you all think? Tube or S.S. for these speakers?

Thiel actually was using an older Krell solid state at the factory when I was there about a year ago.
On the Thiel brochure you can easily see a Mark Levinson N°53 (or the old N°33) just apart the Thiel 2.4

My cent!
After about six months of break in on the 2.4s the bass is loosening up and is now extending quite nicely. I don't have any perception that I need a subwoofer now, though I can see how one could want one when they were new.

These speakers DO need considerable break in time, but they do extend nicely in the lows and really move considerable air. CJ CA200 still nicely powering them.
