Thiel cs2.4 upgrade to cs 2.4 se

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.

These are the video taken from my system  before caps upgrade.

For comparison, i will share the video after the caps upgrade 2 or 3 weeks later when the caps settled in. I welcome any opinions and views after the upgrade.

Hi desmond888,

It is very difficult to judge the sound quality in your video, but I can hear that the sound is nicely open, also notice that your room has a lot of problems with reflections, think it's a good idea to do something about it, the reward will be great!!
