Directional interconnect cables

That he's a Kimber salsman doesn't automatically make him wrong. Just so happens Kimber makes some of the most transparent cables on the market. They must know something! Ever heard the saying: If I have to explain, you wouldn't understand?

Rodman99999, I spent thirty years with AT&T. Tell me more about the industry's stand about cable directionality.
I never heard it. What are your sources? Not an attack, I just want to know.

The latest were the guys that installed my RoadRunner(CableVision) cable. They made certain to string the cable from the pole to the house so it came off the spool the right way(signal/printing-their words). I've not made the topic a point of life-long study, and don't intend to obsess about it. Just know what works for me and my system! I had connectivity problems with AT&T Yahoo for 3yrs before giving up on them. It took 4 "technician" visits before one came to the house that actually knew how to use his own line-testing equipment, and found two wiring defects between my house and the server. Those never did get fixed. I was paying for 1.3M and often getting about 428kbps(windy or rainy days).

Lupinthe3rd - It does not make sense to you because it does not make sense. Believing that a wire terminated at the ends in a metal conductive pin and socket is directional is evidence of a complete lack of understanding of even basic electrical theory and a willingness to buy into any idea that someone proposes that is backed by a misapplication of scientific principles. In order to make a cable directional you would have to add a component that had an inherent directional attribute - like a diode or a polarity sensitive capacitor. Doing that would affect sound if done correctly, but it is not an effect you would want (of course adding the polarity sensitive cap would, with sufficient voltage, give a very time limited change as the cap would fail). You can create your own directional cable with a simple nondirectional cable and a ball point pen (to add the arrow).

An update and caveat - Lupinthe3rd - however, the proper way to connect any shielded cable to connect the shield to ground at only one end, not at both ends, connecting the shield at both ends can cause problems if the two 'grounds' thus connected are not at the same potential. Realize that in most instances when connected a preamp to an amp the two grounds will be at the same potention so terminating the shield at only one end won't matter. This is not necessarily the case when running cable betweeen different systems that are housed in different locations (such as different buildings. If the directional cable has the shield terminated at only one end then that is of value, but again that should not add significant cost to the cable and again you can make your own cable or buy cable with a shield connected at both ends and reterminate one of the ends (and use the ball point pen). So the cables are not entirely snake oil - just don't pay a lot for the directional cable as opposed to the nondirectional cable.
