Jet, look at Jeff Day's blog/thread on the WE IC's as there is a link to "Take Five Audio" for Belden braided tube shielding. They offer various sizes. I used 1/4-1/3 inch as 1/2 inch would be too big. It does expand a little. Hard to work with this stuff. I soldered a 14 gauge solid core copper wire to the tip of the twisted runs and carefully pulled the twisted cable through the braided tubing. Only way to really do it.
I then covered the braid with heat shrink tubing as the braid is conductive as you know. I then covered the braid with cloth.
This was somewhat difficult and time consuming for me.
Yes, the shieded WE version is in between the nude WE cable and Belden in terms of sonic personality. I found it not quite as forgiving as the Belden and not quite as "bright" as the nude. Good middle ground for me anyway.
