Technical and scientific discussion of amps, cables and other topics.

So tell us all May so that we can get it right.....

"Under single- blind listening tests, they both consistently identified the difference between A and B only to be told later that the only difference between A and B was the direction of the one metre length of interconnect between pre and power amps !"

Does wire have a metalurgical orientation? YES, having worked in a wire mill and watched wire being made, it is obvious. Why? How is wire made? It is cold drawn by being pulled through dies to reduce its diameter and work harden it (so much for monolithic crystal wires.) So which way sounds better, with the leading end connected at the preamp and and the trailing end connected to the amplifer or the other way around? Should the wire be reduced in a single pass or in multiple passes? If in multiple passes, should each pass be in the same direction or should successive passes be made in opposite directions? What percentage reduction on each pass? Should it be annealed between pulls or after being pulled or not at all? At what temperature and for how long? Should it be quenched? Passivated? With what acid and at what strength? What if the wire is made of strands, is it better to have the grain orientations all in the same direction, mixed 50/50 in opposite directions, or mixed in some other proportions? What tests do you use to determine grain orientation, electrical or electron microscope or both? What is the optimal grain size? Whose PVC insulation sounds better, Dow Corning's or Dupont's? Which formulation? Which Teflon sounds better TEF or FEP? What about Halar? Does it hold true for speaker wire and power cords as well or just for interconnects. How do you get the power company to pay attention to all of this in the feeder cables they use to power your house? What about the electrican who wired it?

In citing Mr. Atkinson, I remind you he is the man who recently said he must use a digital equalizer to master his recordings accurately to 0.1 db but would not so much as use a treble or bass control to correct wildly out of balance recordings he listens to being played. You hold such an individual's opinions in high esteem? Why?
