Thiel Owners

Excellent discussion- All.
Reading across other Audio forums, Cardas Rhodium/Silver is the preferred binding post upgrade. This technique is applied to loudspeaker as well as Power amp posts. Silver tends to act as a superior conductor on several Audio fronts. Presentation and sound can portray brightness and or lean. At any rate Silver is very fast sounding. One audition with a Nordost cable or cord is all it takes.

Happy Listening!

Happy Friday and Memorial Day Weekend- ALL.

Interesting to read the 2.4 upgrade issues here and the seeming availability of parts. I'm currently planning a complete upgrade  to my 3.7 XOs . It has FXT boards, loosely wound coils, MKT caps, just as @beetlemania describes. I have spent the last several months trying to source components. Nothing at all available from ERSE or Rob for coil replacement but have found everything I need from Jantzen. Resistors not a problem. Caps a big problem but work is in progress. I want to have this all done by summer end and will post.

Wow Beetlemania, you're my kind of audiophile. The few times I posted similar details, and the proper test engineering of listening and evaluating each set of changes, then ranking them, I've been met with crickets. As such, my post you're responding to was minimal.

I do have 0.1uF bypass Multicaps across all three ESAs, and my 13uF coax series is a 10uF || 3uF ESA. (These are in addition to the Lexington Elpacs I mentioned that remain in place) I'm sure there are all variety of better caps by now that improve on both CSA and ESA; that ship has sailed.

Fair point to replace the electrolytics due to loose tolerances and drift. I'll look into the coils and order the resistors. Thiel supplied me with the schematic for the HF XO, but don't have one for the LF XO, though it should be simple enough to figure out. Anyone who has that diagram I'd appreciate it in a PM.

Does anyone know about the changes to the 2.4 woofer that were apparently made after my speakers were manufactured?

ERSE sells direct erseaudio.com , 
I've also found that partsconnexion has the best prices when you wait for their sales and the best sellection for USA postage ,
HiFi collection is another great source but with higher postage rates .

@beetlemania

Thanks ,  I looked at images of 2.4 crossovers , interesting thing is that they all look like circut board material while I thought that Thiel was using a masonite type board like those used in my 2.7's .
But if you look at images of 2.7 you'll see that they look more like circuit board material and I think are demonstrator models .
What is your board material made of ?
