I think it is the elimination of crystal boundaries which makes this so desirable.

That "very special cable cooker" sounds very interesting. I'm currently using a rice cooker for all my interconnects, but I'm always looking for ways to improve my process.

So as some of you know, I used to own a company which manufactured cable for the underwater industry. We also made hydrophones with the extruded cables.
So, cable ITSELF, typically does not require directionality unless one CONFIGURES it that way. Speaker cable especially, but any two wire cable is germane to this topic. 
NOW, it has been brought to my attention by a non-TS user that:
When we get into specialty uses of cable. Like audio/video. In a consumer based audio system, the RCA cable rules. Mixing consumer gear (RCA) with pro gear (XLR/bnc,SPDIF etc) can get sticky with regard to shielding configuration and in some cases the shield may be configured to require a specific "directionality". Similar to what GB has put in this thread.

The directional arrows on cables,.... are not snake oil [ed: MIGHT not]. They are completely legitimate, and indicate the direction of the shielding of the cable.
There are so many types of cables that it becomes a bit, well, esoteric, I suppose. But, in unbalanced cables, your basic RCA/RCA level of stereo user interconnect (read: not balanced, professional/recordist level), you connect the shield to the upstream piece of gear, only, and leave it open, not connected, at the downstream end, if you want to shunt off EMF/RF signal. Otherwise it just passes that crap downstream towards the end user [ed: device]. The arrow indicates directionality of shielding for shunting back to the upstream devices earth/negative post grounding.
This makes the unbalanced cables completely directional, as a shunting device.

This cutting off the shield at the 3 wire end has been A PITA for me all of my soldering life, which is why I mostly choose not to solder my own stuff any longer and rely on folks like Ted G!

Thoughts? discuss amongst ourselves?
