07-19-15: TbgIt is true that the conductivity of tin is roughly about 6 or 7 times lower than the conductivity of copper. However, to provide a quantitative perspective on that difference in the context of the WE speaker wire, and assuming (as I suspect) that the layer of tin comprises just a small fraction of the cross-sectional area of each strand of the wire, consider that the difference in conductivity and hence resistance between that wire and a hypothetical similar wire made of all copper would be vastly overshadowed if the copper/tin combo were simply made one gauge size larger.
John421, all copper cables would be more conductive, especially if the ends are not soldered on.
And in many cases the conductivity and resistance of a speaker cable of reasonable gauge won't matter anyway, especially if speaker impedance is not particularly low and cable length is not particularly long.
07-19-15: John421Sorry, but I have no idea. And I doubt that anyone else can say with any kind of certainty, unless they have compared the WE with a variety of modern tin/copper cables, and with a variety of speakers and amplifiers.
Would todays tin/copper cables have the same affect as the Western Electric style cables?
