Thiel Owners

Tom Thiel...All new drivers and crossover design and components in the same cast granite cabinet with port extension and improved mechanical resonance tuning. 
Same Sonoran Signature wire with Micro Bearing but now with Cardas speaker connectors. I plan on treating all connections with the 1260 Elixir from High Fidelity  Cables..this product is remarkable.  I will also treat the tensile leads with this near super enhancer. Tom

I would like at ask the help of anyone that has the same COAX driver as on the Thiel CS3.7. Today when I was listening to the new George Harrison's ALL THINGS MUST PASS (50th Anniversary / Super Deluxe) I heard something from my RIGHT COAX driver that makes me think it is damaged.

At 39 seconds into the song HEAR ME LORD (Disk 2) I hear some distortion from the RIGHT COAX driver. I can reproduce it every time on the CS3.7. However, I cannot reproduce it on my RAAL SR1a headphones nor KEF LS50. The RAAL is hooked up to almost the same setup except for amps. On the RAAL I can sense that at 39 seconds there is a 'hot' sonic passage but the RAAL does not sound distorted.

The 2 COAX on the LEFT and RIGHT are only about 8 months old and never played loud. So I would be surprised if they are damaged. A bummer if it is but I can replace them myself.

is this a CD or LP set? I have the CD set arriving soon and can test on a fellow Audiophile's CS 3.7 speakers.  Stand by until one of the CS 3.7 owners on the Panel chimes in to address your query.

Happy Listening!

TomTweak - these speakers seem chock full of exotic solutions. Have they been submitted for review, or do you have any white papers or third-party commentary? 

Beetlemania may have directly compared coils to coils 

I did not make this comparison as I replaced all caps and coils at the same time. Not possible, with so many simultaneous changes, to isolate the sonic differences from coils. I spent close to four months elapsed time making changes, allowing burn-in, and making sonic comparisons in mono with the modified and “reference” channel. 
1) OEM FST boards (sandcast resistors) to FST with Mills MRAs
2) FST with Mills to Masonite boards with Clarity CSA throughout, Mills, and “Lex” or Erse foil coils, the latter on feed positions (ie, everything different except Mills)
3) New boards with and without Multicap bypasses on coax feeds
4) 160 versus 250V caps on woofer shunts (I heard a difference)
5) OEM hookup wire and binding posts versus Cardas wire and binding posts
6) Single versus biwire from amp

I would not lose sleep over unavailability of six nines coils. If you have these in your classic Thiels, great! If you have FST, see if Rob Gillum has “Lex quality” or buy the best you can. I mean, we’re talking about speakers 10-30 years old that were modestly priced to begin with. Sonic improvements from better caps and resistors are notable even if I can’t really speak specifically to coils. That said, IMO, it’s worth putting foil coils in the feed position as these are not expensive.
