Thiel Owners

I actually find the 2.7 sounds a bit more like the earlier models vs the 3.7.
The 2.7 has that slightly tighter, denser, focused concissive quality I'd always heard from Thiel - the 3.7s being a bit more of a departure - smoother more lush.   This is fairly subtle stuff, though.

Happy Friday- All

Thank You Prof 
Your in-depth evaluation is fantastic, Its to bad the the " professional "
evaluators couldn't be as precise as you.
You've help me get over the regret of not moving up to the 3.7s
I purchased one of the last CS2.7 pairs available from Thiel,
I had to purchase the speaker spikes used on the 2.4SEs and 3.7s
in order to penetrate the carpet.
I love the sound and the looks and they aren't so heavy that I'd need help to move them.

I have owned 2.4s and currently have a pair of 3.7s.  To me they sound best with a high quality tube preamp and a SS power amp. They really need 250+ watts and you need an amp that is stable down in the 2 to 3 ohm range.
