Dan, it is a matter of record on this forum that you believe any difference in wires makes a sonic difference. I think you once said, "every wire has it's own sonic signature" or something like that.It's also evident that you have an electronics background, both by your own claim and in the posts you make, we can see you know some tube circuit theory.
So with that in mind, in technical terms, why do you think different wire materials have a sonic difference in these otherwise controversial applications?
Ok, you did some extensive listening tests and heard differences in nearly every case IIRC. So what do you think is going on electrically?

not dan but silver behaves differently when soldered. Unlike copper it melts with the solder giving it more of an alloy than a junction of dissimilar materials.
(not sure exactly how to put it but the way you can be sure your wire is silver is simply dip it is a solder pot and if you keep it in there too long it will dissolve (melt?)

Copper too alloys with or dissolves in solder. This is why plain copper soldering iron tips pit and need frequent dressing. Iron plated tips pretty much eliminate the problem and are much longer lasting.
Mostly it is more metalurgy than electrical.
Copper is softer and has more resistance
and therefore has a warmer mellower sound.
Silver is harder and has less resistance
so it has a more strident articulate sound.
Aluminum I have not tried but was a fad years ago.
Some dope gold with the silver to mellow it.
Also the insulator is another factor.
PVC dampens the sound.
Teflon sharpens the sound.
Cotton/Air is in the middle and sounds more neutral.
OCC/Single crystal wire cleans up the sound nicely.
Then there is the shape of the wire.
Round will sound different depending on the gauge.
Flat sounds has the most neutral wide band response.
I have not tried rectangular yet.
Mix and match to your taste and system.

silver's resistance is about 6% less than copper (or was it 4%).
Actually, though, for hardness both copper and silver are remarkable alike. That is the principle reason why silver smiths alloy copper with silver to make cheaper silver ware. When working the copper-silver sandwich the metallurgical properties are quite similar and you can hammer and shape the sandwich with little issues from the dissimilar nature of both metals.
Still I find it useless to argue with those who claim no difference. Let them believe what they will. After all after miles of electrical wire coming to your home from the power plant, who needs a PLC?

Is this all a joke, or are you being serious? It is hard to tell...

Well it is no wonder, then, that attempts at rational discussion get nowhere.
