I see that this company are offering to Silver plate UK mains plug pins, might this offer any meaningful conductivity advantage over the incombent brass pins of UK 15 amp plungerry ? A mute point for my part as being in the main a Schuko kinda guy.

They offer LP12 upgrades. That pretty much says it all really. Silver isn't as good a conductor as copper and tarnishes quite quickly especially when exposed to light. I wouldn't bother.
Geoff, I think that you need to research a little before altering the accepted table of conductivity, whilst Silver is marginally *More* conductive than Copper, we are discussing the metal utilized in the construction of Uk 15 ampers which happens to be an alloy Viz. Brass, which is notably less conductive than either Copper and more pertinently Silver, albe it a plating. Now whether one may perceive any audible differences be a whole nuther matter.
I didn't say it was less conductive, I said it wasn't as good a conductor that is because it tarnishes which introduces other problems. If you silver plate brass you introduce another set of problems, unless you strip the plug completely and plate the whole pin, in which case the Silver on the surface will be the conductor.

I am unconvinced that simply plating a connector makes any significant difference except that Gold will prevent surface corrosion. A much better option with a mains plug would be to substitute a different alloy, no I can't remember which one might be an improvement. However the limiting factor is the contact area between pin and receptacle and in this respect the 13A plug is pretty poor.
