Thiel cs 3.7 vs Rockport Atria

I have the possibility to purchase a new pair of Thiel cs 3.7 at a good price but am also interested in Rockport Technologies Atria.
I absolutely love the sound presentation of the cs 3.7 and find them very musical.
Can anyone give me their opinion on Rockport Atria which i haven't had the chance to audition yet.
My amp will be Karan Acoustics KAS 600.
I'd consider getting the Thiels while you still can, their days of availability may be numbered.
Well unfortunately they are no longer available but i can purchase a used pair in perfect shape for half price of a new.
Obviously Rockports is not the same budget.
Both Thiel models- Cs 2.4 & CS 2.7 are my reference.
The CS 3.7 is too large for my small room- remember- the 3.7 needs 20x20, 25x25 or 30x30 sized room(s) to sound their very best.

One will be hard-pressed to find a better loudspeaker- does everything right, very musical w/ all types of genre. Do not forget a robust power amp to really make these babies sing!
Happy Listening!
My room will be 15x20 which i think is enough for 3.7's.
They are a 2009 model therefore i will have to make the lastest upgrade that was available starting from 2013 i think.
By buying the Thiels rather than the Rockports, that you'll have enough money left over to buy a couple of used Thiel subs.;-)
I won't need subs because my room is not large enough.
The extra money for a better DAC-Preamp.
