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.
Thanks.
128x128thieliste
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.
