Thiel CS 3.6 vs 3.7


Replacing my model 3.6 speakers has come with a great deal of hesitation. I purchased them used from a dealer in 1993 after owning the model 2 2s. I have recently acquired a pair of 3.7s that are shipping as I write this. I understand that "beauty is in the ear of the beholder", but has anyone had both and had a preference? I ask because I do think collective wisdom is important and I do not want to be in the position of letting the "newer and improved" mentality creep into my judgment. What differences could I expect to hear? Context is Hegel Mohican to Audio Research Ref 3 to McCormack (SMc Audio) DNA 1 with almost all mods including Plitron transformer. Balanced throughout with AQ Columbia XLR and Kimber Monocle XL speaker cable. AQ Niagra 1000 conditioner and Shunyata Alpha HC power cables. Thanks in advance.

That is great that you sent it to Rob. If I sent mine to Rob he would say "no mas".

I also had a few cosmetic issues. The first one being the aluminum shell had a few annoying looking scuff marks. I contacted Rob and he told me to use a specific spray paint on it. I did that and it looks great now.

I had a lot of marks on the veneer and I decided to paint the veneer black to make an all black speaker. I bugged my local paint store half a dozen times for advice before I had the confidence to paint it. That paint job also turned out great. Not as good as a factory job but a ton better than the scratched up used speakers I bought.

I am also putting 2 new COAXs (from 2014) and replacing my COAXs from 2008 and 2012 (maybe keep as backup if they are not damaged). I also got some outriggers in the case my son tries to climb it. I have a feeling my crossovers will need some repair. Fun times.

BTW - I never heard the 3.6 but the 3.7 is one of the best speakers I have heard. I have heard quite a few speakers. The 3.7 always sounded correct to me (my current messed up used speaker notwithstanding).

Nice score! on the CS 3.7 loudspeakers. Your gear is a sonic match for this model. I am especially interested in reading more about the system featuring Hegel Mohican cd player. 
Once the CS 3.7 settles into your room/system, feel free to join us over on Thiel Owners thread. We have several 3.7 fans/owners on the Panel.

Happy Listening!
So sorry to hear about issues with your 3.7s. I hope you can get them up and running. As far as my system goes, it has taken many, many years to get it to where it is. I searched for used gear and bought nothing new. I did have a few issues with some equipment, but I have found the audiophile community to be quite trustworthy. As far as the Hegel Mohican is concerned, I have been pleased, in general. There is information on my CDs that I was unaware of based on what my old player was able to retrieve. The Hegel is analog-like, sweet, and has changed my perception of much of the music I listen to. It has a very low noise floor, great dynamics, and an excellent soundstage; Wide, deep, and fully-formed. There are some things about the function that are IMO clunky and not at all reflective of any product that costs as much as Hegel asks for this machine. 
The problems I am having are somewhat fun since I am fixing them 1 by 1. If it did not cost money I would have no issue at all :). I am learning a lot by the things I am finding. I hope to have everything ready to go either next week or by the end of December. The health of the crossover will determine the timeframe.

I took measurements of the CS3.7 recently with the REW software (free) and a $100 Minidsp microphone. A great learning experience from that too.
Wow! That is a deep dive into the 3.7. I am not that technically competent and have to trust Rob's expertise and judgment. Happy to know that you are learning the details. I do not know if you have seen this or not, but I found it to be quite interesting. Best of luck!
