Thiel Owners


I just scored a sweet pair of CS 2.4SE loudspeakers. Anyone else currently or previously owned this model?
Owners of the CS 2.4 or CS 2.7 are free to chime in as well. Thiel are excellent w/ both tubed or solid-state gear!

Keep me posted & Happy Listening!

My CS2.4 serial number 384X, the last digit faded out unreadable, this is xover photo taken 5 years ago before modding.

Thiel 2.4 SN 384x orginal xover




My Thiel CS 2.4s are serial# 2951 and 2952. Purchased pre-owned from Audio Consultants. Speakers were approximately 5 years old at time of puchase in April of 2011, with 5 years remaining on the warranty.  So presumably manufactured some time in 2006.  So with respect to the boards and parts, where does that leave me?

Additional factoid: On my Thiel Warranty Registration, date of sale to original owner is listed as July 6, 2006.

The pictured XO looks just like mine. If 2951-2 look like that, they're from the same era. Those black caps are polyester-mylar (one down from polypropylene), the coils are well-made from CDA-102 wire, which is high-end regulation wire, one step down from Thiel CDA-101, which is the best available. I tested these resistors and found them to be the non-inductive resistors that Jim had designed and made by ERSE. Although they look like normal sand-cast, but are better. Note that these PCBs are actually point to point layouts with no traces that can cause troubles. This wire has Thiel signature teflon insulation. All in, I would be happy with these boards, unlike some we have seen with obviously poorly wound coils and unknown insulation.

That said, if you're DIY-inclined, you could elevate the sonics by upgrading all resistors to Mills MRA-12s and all film caps to CSAs with the 100uF electrolytics to some upgrade recommended on this forum. I have eliminated all electrolytics and have developed an affordable CSA-type 100uF cap that works well. Not ready yet. 

I don't want to open Pandora's Box regarding product iterations and quality levels. I'm told that all 2.4s were assembled in Lexington, approved by Jim and tested to the historical standards. I have expressed my personal disappointment that some particulars of parts quality eroded after my watch. But, compared to competitive products in design and execution, I suspect Thiel stayed way up on the value charts.

jazzman - you should be fine. It seems most of the "difficult period" might have been 2003-2004. Thiel probably found better sources, plus China definitely improved its development and manufacturing chops year on year. 

The the tell-tale test is looking at your boards for the winding quality of the coils.
