In Reply to: Is triple braided wire in most cases shielded good enough? posted by johnvb on February 17, 2007 at 07:25:15:
As long as the braid is tightly woven. The Kimber version is subject to RF due to the spacing.
Have you seen this stuff, is it tight enough? Actually it looks very similar braid-wise, to my PBJs.
Should I braid my own, with single conductors, for a tighter wind?
I've been looking a lot into braiding lately. While tighter weaves may be less prone to picking up RF, looser weaves sound better, or so people say. Here's a link to 3 braiding techniques:
What braiding does (in cabling) is work to minimize RFI by cancelling it out. There are more technical explanations all over the net, so google to your heart's desire. But the central point to it has to do with Common Mode Noise Rejection.
In my experience, Home Grown Audio makes GREAT speaker cables, and is one of the few to sell its braids bulk. But personally, I found that using copper 24AWG (CAT5/6) cable in my system sounds better. I had previously used the HGA SC-16 (Solid Silver 16 Strand Speaker Braid)
The weaving is well done, but for my personal tastes, not nearly as tight as I like it. With CAT you can braid very tightly. But be careful, there are some drawbacks to overly-tight braided designs. I suggest getting a very sensitive DMM and taking resistance measurements between your construction phases. Capacitance meters aren't that expensive either. These types of designs tend to vary in capacitance values depending on the tightness of your weave.
Thanks for the link!
