RE: stranded wire????

Hi Dave,

I must admit to being skeptical about most of the claims of noticeable effects resulting from diode junctions between dissimilar or oxidised surfaces, etc. Would there, for example, actually be any significant potential difference across the junction in any case? If not, it is hardly going to matter whether it is a diode, or non-linear in any other way. If we consider some poor contact between two adjacent strands in a multi-strand wire, then the potentials at side-by-side points on the two wires would in any case be essentially equal, and so no significant potential difference between them.

It seems to be a little bit like worrying about whether a diode connected in parallel with a piece of wire will affect the signal transmission properties of the wire. The answer is no, since the potential difference across the diode will be essentially zero, so it never has any possibility of injecting non-linearities into the signal.

And in a case like an interconnection wire between tube stages in an amplifier, the impedance of the wire is utterly insignificant compared to the input impedance of the stage it is connected to, and so things like the skin effect, the possibility of non-linearities from diode junctions, and so on, is even less important than in a higher-current application like a speaker cable.

If these alleged effects actually occurred then they would be measurable. As far as I know, there are no substantiated reports of such things occurring. Of course some audiophiles want to have it both ways; they will invoke the alleged "science" of diode junctions at oxidised surface interfaces in order to justify why they spend astronomical sums of money on super-pure cryogenically-treated wire or whatever, but will then instantly reject science when anyone suggests actually trying to measure the effects they are talking about...

I think some "high-end" manufacturers have perfected the art of pulling money from the audiophiles' wallets while they pull oxygen out of the wire.
