Thiel Owners

@tomthiel I am able to find (at Parts Connexion) Clarity CSA parallel combos that will give me the CS2.4 capacitance in the coax (14 and 28 uF) and woofer feeds (33 uF). Reading this review of capacitors: http://www.humblehomemadehifi.com/Cap.html it is tempting to match the Clarity with Mundorf (writer suggests 90% Clarity and 10% Mundorf). But I can’t get the exact Thiel values with Mundorf combos. For example, I can get a 22uF CSA and and 5.6uF Mundorf. How critical is it to get the exact capacitance value, especially given that these are rated +/- 2-3%? It is possible to add a third in parallel, eg, 22 + 5.6 +0.33 = 27.93. Do you recommend adding the third capacitor to get closer to 28 uF?

Also, what are your thoughts on adding 0.01 uF bypass? I might try adding a Dueland or Cornell-Dublilier 0.01 to my existing SA in the coax feed - seems like a potential best-bang-for-the-buck mod - but not if you think that’s a bad idea.

what gear is in your system now?
Happy Listening!

Beetle, I do recommend coming as close as possible to the original value, since that affects frequency balance and phase addition through the crossover. I am a big fan of double-bypassing and like your idea of adding the third cap to hit 27.93uF. That 0.33 cap can be ultra-quality which keeps the razor sharp leading edge transients from smearing.

I think that your first proposal built on CSAs is a better idea than the 0.01uF ultra with the SAs. CSAs seem to be a big step up from SAs, which were ClarityCap's best in their day.

If you do this mod, I would appreciate you modifying one speaker and perform whatever comparative tests you can between old and new. We can build a knowledge base here on the forum for the benefit of all, including yet to be identified upgraders everywhere.

Thank You- beetlemania 
for your diligent work regarding updating/upgrading the caps in our speakers. Keep up the excellent research.
Happy Listening!

Tom,
They were indeed Brazilian Rosewood... you picked the pair personally.
I requested a bold pair with great patterning. You chose this pair because I THINK (29 year old memory) that this pattern had 'great cathedral pattern? No,  I sold them about the same time I was going through a divorce. They were not only stunning looking, but sounded other worldly.
I miss them to this day.
