Thiel Owners

anzen - welcome. There is quite a bit to unpack. I’ll make a brief overview here as a bit of an update of work in process. All of our work is well beyond the SE version. The SE substituted only 2 feed caps, changing nothing else. That ClarityCapSA was their state of the art about 20 years ago. Major improvements have ensued. Extensive comparisons have landed on CC’s CSA with copper end caps - Purity is even better, plus a super bypass can be paralleled for greater definition. RTX or Duelund .01 to .1uF where it matters.

Your coils look good. Keep them. Foil coils would change other parameters and would require redesign. Resistors are worth replacing. Mills in series feeds, others can be Dayton precision 10 watt or their 20 watt (hollow tube) vairety if values available. (from Parts Express).

Regarding boards, it’s not so simple. Your coil values are tweaked for PCB mounting. If you revert to P-to-Point, slightly different coil values are required. Also we’ve learned that one-sided wiring of masonite P-t-P is sub-optimal. So, an entirely new layout scheme is required with edge mounting rather than stock flat mounting of the boards.

I am pleased to be working with duramax747 on CS2.4s as a live developmet project. But whatever comes of that, your largest consideration is your budget. You could responsibly spend $thousands or $ hundreds depending on the scope of your choices.

Send me a PM if you wish.

And on a bright note to all: remember those custom Clarity and Purity caps from last year? They’re scheduled for delivery this week after an odyssey of delays.

Hi @jafant , appreciate the warm welcome and you have been moderating a great topic!  Make any changes to your 2.4 SE's?  I'll share more on musical tastes and system in the next few evenings after work.

Thanks for the correction @vair68robert!  I should have said series (Rt = R1+Rn) vs parallel with just 2 resistors as the site you link pointed out Rt = R1*R2/(R1+R2).  You are right about capacitor sizes which was reenforced looking at @beetlemania crossover pictures.  The switch to Masonite seemed to be required at some point for film capacitors and perhaps even for the resistor switch using the 2 resistors you kindly provided or the 2x8ohm I have.  As @tomthiel said, is "not so simple" and my mind hasn't quite fully realized yet.  Quite a lot to learn. 

Hi @tomthiel, I appreciate the information and clarity.  The project with duramax747 will certainly be of interest as I don't have a clear understanding of the desired end scope.  The new layout scheme, ClarityCap PUR and more learnings along the way would be good to know before going too much farther with the build.  

Frankly, my technical knowledge is being relearned from a job building magnetic card readers for video game arcades back in college 25+ years ago, so it is rusty but starting to comeback and expand.  Part of going with ClarityCap SA capacitors from Rob to get the crossovers in hand and study the existing design beyond photos and documents.  It was a straight forward update vs CSA (i.e. 27uf+1uf, unknown size constraints). Good learning experience plus, out of pure curiosity, I wanted hear what the SE model might have sounded like.  Not too logical from a project perspective though the SE sound has been enjoyable.

Audiogon might have a minimum requirement for sending a PM, so either I missed how it's done or needs to be enabled.  Will send one when that is figured out. It's been many years since being on a forum.

My pleasure to be of service. Where are you located?

No, my SE are stock. I would not mind finding a donor pair for Tom’s upgrade path.

The stock CS2.4 is a real Honey.  Curiously, I had to have a taste of the SE.

Once heard, there was no retreat!  I was very fortunate to have heard pair 50/51. I was fully prepared to purchase those at full Retail, but the owner did not want to sell.  I tried.

Happy Listening!

Jafant,

What are your thoughts on the red stained birds eye maple finish on the CS 2.4SE?

My understanding on the serial # is it does not matter how low the number is as the  internal xover boards are the same as the higher numbered CS 2.4. You mentioned 50/51 so didnt know if you were aware of that.

Good to see you here today. Thank You for the internal Boards clarification.

The Red Stain Birds Eye maple finish is stunning! Just gorgeous and totally matched the “personality “ of the SE.  The speaker is quite attractive perched on Outriggers. I am proud to own such a Loudspeaker.

Happy Listening!
