Geoffy, how would you advise a cable manufacturer to determine the directionality of a piece of cable?
>>>>Well, Sleepy, there are two ways to do it. The easiest way is to cut a section of WIRE off the spool - mark the section of wire to keep track of how it came off the spool - and measure the resistance both ways from end to end. The WIRE direction that has the least resistance is the proper direction. Then you know how to construct the cable. The other way is to make up an audio cable - marking how the WIRE came of the spool - and listen the cable both directions. The direction that sounds the best is the proper direction. Then you will know how to keep track of the wire as it comes off the spool. That how you control directionality of any cable or power cord or HDMI cable or Ethernet cable.
