Carl109, "...studied, researched and set in stone," maybe in EE to give the engineering capability to design circuits, but in reality there are many more factors than totally explain why wire has directional attributes. If most people hear a difference between speakerwires used in one direction rather than another, what is it that explains this, especially if there is an overwhelming preference for one way rather than the other?
Omega Mikro goes to great extremes to be certain that the wire draw direction is maintained. On their power cords, the Red is with the wire draw from the wall to the IEC on the hot side and from the IEC to the wall on the neutral side. Their Blue cords are the reverse. What a small number of components show no difference whether a Red or Blue are used, many show great differences. This is with simple 60 Hz ac. Kondo is very concerned with the wire draw direction on his wire.
Such designs are not "disregarding" what electrical engineer suggests, but rather going to other concerns. There are many things that manufacturers use to help sell their products and certainly some "improvements" are baloney but some that go above and beyond simple rules of electronics have great benefit.
