Something about Thiel CS 3.7

Hello Guys,
I own since ten years the Thiel CS 2.4 (not SE) and I'm still happy with them but someone offered me the Thiel CS 3.7 as change with some added money.
Theorically should be an improvment respect my 2.4 expecially regarding the easyest load .. my 2.4 run with Primare A32 solid state amp.. that does a good job on them.
The 3.7 reading specs has 90db efficiency and 4 ohm load with a minimum around 2.3ohm while my 2.4 87db same 4 ohm load but a deep around 1.2 ohm .. not easy for amps.
Someone here tried both? .. and what do you think about?
Thanks in advance for your reply!
Regards,
Curio

It's been a long time since I was on my Thiel journey, but I went from 1.6s to 2.4s and had every intention of moving on up to 3.7s until Jim died and I decided to go a different direction.

In all that time of lusting after the 3.7s, I never once read about the 2.4s outperforming them.  As @dweller stated, my every impression was that they were a big step up.  If you're committed to Thiel, then I think 3.7 vs. 5i vs. 7.2 is more debatable.  I personally would go the 3.7 route.

Depending on the size of your room, the 3.7s should be a significant step up.  They'll certainly go deeper in the bass.  Only concern could be overloading your room.  You might check the Thiel Owners thread, lots of knowledgeable Thiel owners there.

Yes, 3.7 should be a big step up (if your room is small, maybe not so big). Thiel's are quality no matter what size. Some of the best sound I've heard was from the 1.6s in a mobile home with a BAT integrated. I've also owned the 2.4SE which was stunning. The ONLY concern is getting service if anything should break (company out-of-business). I think Jim's brother is providing service now so you might want to inquire before purchase.

@dweller Yes indeed: https://www.coherentsourceservice.com/

And agreed, posting in the Thiel owner's thread will get you a wealth of information:  https://forum.audiogon.com/discussions/thiel-owners-2

I own the 2.4 and have also had them a long time. I demoed the 3.7 a number of times. The 3.7 is in a another league. It is an amazing speaker. Today it would cost $18k or more if it were still out. 

It will do everything your 2.4 does only better. They are cut from the same cloth so it will be evolutionary rather than different. I would take that upgrade in a heartbeat. I don’t know your amp but I heard them on a musical fidelity A5 (“cheap” integrated) and it blew my mind. I am more jaded these days as I have been exposed to a lot more stuff.
