Hmm ok Barry , will bow to your greater knowledge , no doubt thats what caused Alan to chuckle too.

Agree with 110, it used to be a rule of thumb that arcing occurred in air only when the voltage gradient approached 1kV per mm.

Probably not quite the same thing, but if I recall, metal surfaces with different potentials create 'microwelds' when slid or pressed together.
It is impossible for anything digital to sound analogue, because it isn't analogue!

Correct me if I'm wrong but in any interface of different metals can lead to potential differences, thermocouples being one example where the effect is desirable, not so much in hifi as may add more noise. Hence the removal of fuse plating.
Silver solder being less harmful to signals than standard solder being virtually indisputable, though I'm sure someone will

Well, yes and no. The key words in the above quoted sentence are ‘can’ and “potential’ - it’s certainly not a given that the differences you allude to will be created, or even have the potential to be created. Bi-metallic strips and the like are very much extreme examples and not a model for fuse plating etc.

Even if you could demonstrate that difference you've then got to demonstrate how it affects the varying voltage going down the speaker cables to the drive units. After it has passed through the amplifier. And then you've got to show that makes a difference to what we are actually perceiving. If there is really something going on it is the realms of the unknown unknowns. So good luck with the scientific explanations.

Not seeing how bimetallic strips that bend due to different rates of expansion when heated, as in a toaster browning control, is comparable to potential differences generated by heat across two joined ( usually soldered) different metals and used, for example, in Autoclaves Ovens for temp measurements and this potential difference is also at room temp, although not as pronounced. I will though concede that they are very small voltages.
