Thiel cs2.4 upgrade to cs 2.4 se

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!!

Dear holco,
Thank you for your concern. In fact, i dont have any room issues. I have a tall ceiling, it is about 14 feet high and my system is opened and layback. If i play full orchestra classical music, it sounds like i m sitting in the concert hall with a tall ceiling.
I guess  the video picked up some echo from the back wall where the recording was made.

Btw, may i know what brand of the solder thiel is using? I found out that the melting point is higher. I used wbt solder with silver content but intend to use thiel solder to match with the rest of the soldering points.

Beetlemania, for my curiosity, may i know what brand of the mpt caps thiel is using ?

I have really enjoyed reading your thread. You have quite a DIY skillset.
Hope your project is going well.  Happy Listening!

@desmond888 
Thiel used unleaded solder (high melting point) but I do not know the brand. I am using Cardas (leaded) for my new boards. In my case, I plan to replace everything from the terminal posts to the driver wiring. Posts and wire will be Cardas, so OEM solder is completely omitted.

I do not know the brand of caps Thiel used on your boards. Solen is a good guess but I suggest you ask Rob Gillum.

Are you still hearing an imbalance with the woofer? Did you change anything on the woofer board? The 2.4 layout I have says the DC resistance is 32 ohms for the coax (measured from hot in to hot out). @holco posted the same layout but someone wrote 31 Ohms DCR. My new board checked in at 30.4 ohms. I will measured the OEM board very soon to see how it compares. DCR on the woofer is <1 ohm. My new and OEM woofer board measured 0.4 ohm. Changing caps and coils can affect DCR even if the resistors are the same. This could have small effect on the sonic balance but shouldn’t change to the degree you reported. Perhaps something else is wrong?

Also, I am surprised you report no problems with your room. I suggest a few simple wall coverings, such as throw rugs to the side and rear wall, to dampen early reflections.
