Thiel cs2.4 upgrade to cs 2.4 se

Thanks holco. Finally, i managed to get it removed from the enclosure. Removing the caps and having the csa caps soldered are not easy tasks for amateur like me. I did the soldering within the enclosure as i was  reluctant to disconnect the connecting wiring.  I took about 6 hours to eventually completed the task.

Attached  herewith some photos for sharing.

Initial audition showed that the high and mid are more resolved, sweet and opened as opposite to be more recess for the original caps. In addition, the timbre and textures of the instruments are more prominent with more mircro dynamic and details.

The only complaint is it is not as balance as yet with the high and mid improved at the expense of lower bass. In particular, the ratio for high and mid overwhelm the lower bass.

But It is not fair to make such a negative comments now as the caps need time to run in. 

My opinion is it is a great upgrade and i shall post further comments after the caps have run in.

Thank you guys for the wonderful advices.

For information, i used hot glue to hold caps to the board.

Great desmond888 :-)

Apart from what you describe, the most striking difference to me was that the space was depicted much larger, how did that work out in your case?

The degradation of the low-end is not something I experienced, I would even say that for the modification the low/mid was leading at the mid/high and there is now a better balance.

In theory, that is also true because a capacitor (the best capacitor is no capacitor) is much more detrimental to the signal than a bass coil.

In my situation I also use a closed DIY dual opposed 15inch subwoofer (> 45Hz) and the setup is tuned with Dirac-Live (MiniDSP), in my case a big improvement because the stereo setup is placed in the living room.

@desmond888 You might post this over on the Thiel Owners thread where Tom Thiel will see it. Your perceived shift in balance *could* be an artifact of altered total resistance on the coax board compared to woofer board. For example, the CSAs might have less resistance than the original caps. Might need to change the resistors to bring the balance back. But get Tom’s advice before proceeding! It might also be that your experience is shifted more so than actual frequency response . . .

Your boards appear to be second generation for the CS2.4. Printed circuit board but with good quality caps (MPT) and coils. Again, I strongly recommend upgrading the resistors, after you consult with Tom Thiel regarding possible value change. But good job!

The radiator can be a real challenge. It seems that there is one sweet spot where you can get it in or out and finding that spot is frustrating!

Dear holco and beetlemania, 

The mid and high have opened up with more air and sense of space. The tonal balance has shifted towards slightly warmer as compared to very neutral in the original caps. All acoustic instruments  sound wonderful particularly violin as it sounded sweeter but less impressive for modern instruments. Imaging also improved significantly with a larger object.

Nevertheless, i hear the sound is changing with the caps started to break in. I shall post my exprience and seek advices from Tom  in thiel owner thread after the caps have run in.

Perhaps, i can post a video for sharing.
