Their litz-stranded cable uses individually enamel-insulated strands. That enamel needs to be removed so you can tin and solder the wire. The easiest way to do that is to dip the strands into a solder-pot for a few seconds, which will burn off the enamel.
A suitable solder pot can be had for $25 or so.
I was specifically referring to doing it to someone’s Focal Elear cable as part of this deal, and making that first tutorial a special-purpose one (simpler, shorter, quicker and very specific).
Essentially they’d get the balanced cable they wanted and I wouldn’t have to spend $200 to buy another Elear cable to illustrate the work on - as I’ve already re-terminated my own.
I appreciate the offer, but this is really just about the Focal Elear cable.
It’s easy … as long as you have a solder pot. Cardas have a video on their site demonstrating how to deal with it.
Though once I’ve done a couple of articles on the basics, I could see doing one on different cable types (included litz-stranded/insulated stuff like the Cardas and Norne wire).
As a rule, I don’t work on cables built/modified by anyone else. There are far too many variables that its not worth being “the last person to touch it”.
I either do full-custom builds or one of my own line of high-end designs.
Very occasionally I will re-terminate a stock cable - but generally only for myself, and even then not something I’ve done since developing my own modular cable setup.
