@yabe1951. Nice amp and speakers you have. I own both the 3.6 and CS6. Thielist makes a good point about tradeoffs. I am using the CS6 because I have a large room and the 6 is more dynamic than the 3.6.
However, the 3.6 is the most transparent speaker I have had in my room, you give up just a tiny bit with the larger model 6. They are definitely cut from the same cloth - both are excellent. The CS6 fits my needs in my room better.
I never warmed up to the 3.7 after much anticipation being a longtime 3.6 owner. I thought Thiel got a little aggressive on the price 12K to 14K. I know it was innovative and an upgrade but the 3.6 has always been my favorite speaker. Hope that helps your decision.
