Copper, silver, or gold MC cartridge coils?

Dear @don_c55  and friends : I think that this example could help to support what I posted about the importance priotiy of cartridge wire type that I said is not so important as we could think.

This gentleman own several top phono cartridges including the Anna, Goldfinger, Etsuro and others ones:

I understand that he owns not one but 2 Etsuro really expensive model and things are that the Etsuro use cooper wwire in its coils but ask
@mikelavigne about the Etsuro quality level performance and even against the other top tiers he owns and owned.


Here another example with the Hana top line cartridge with cooper wire in its coils where and Agoner just posted that he left it gone his Koetsu Onyx in favor of the Hana one and like @mikelavigne he owns the Anna too:

I insist in my point of view due that I can see you are just tilted to look for the superiority of each kind of wire in a cartridge design and for me just that " superiority " does not realñly exist because you can't prove it the superiority either way.

Btw, even its high price differences between the Hana and Etsuro shares one " thing " in common that were designed by Excel.

Regards and enjoy the MUSIC NOT DISTORTIONS,

Important to remember that all posters are listening/posting on their differing systems, so this isn't a reference debate.

Gold is better. Its something like 90 times the price of silver. Also its much lower price volatility. The contrarian view however is the ratio reverts to more historic levels around 20, in which case silver rises more than gold. Granted we are talking about the salvage/recycle value of some tiny fraction of a gram. Still, it's a lot more than the sound difference you were asking about. 

Don : Do you think that these kind of music lovers/audiophiles buy or bought their cartridges because the cartridge coil wire type/kind?, no way almost no one decides on a cartruige thinking on that specific characteristic because it's just unimportant against the whole cartridge design.

@slaw  obviously as you said it's not a reference debate because there is no true reference about. We are just audiophiles not cartridge designers that are the ones that probably have something to say but I'm not sure they could have a debate about because  ( again ) the whole desig/sum of the parts is the really important ( what it counts. ) main issue.

I had a gold wired cartridge, a Clearaudio DaVinci. I thought the Ortofon Windfeld Ti was a better cartridge. But I could not say it was because of the wire. Do the metals really sound different? They all work harden but I think copper does this easier than the others. I tried searching for the answer. This would mean copper wires that are being vibrated will break sooner. The other metals may be more durable. I have had two cartridges that fractured copper wires, a Denon D103 and a Sumiko Talisman S. They were decades old when they did it. Both with copper wires. 
There is a slight difference in conduction but will that effect AC at audio frequencies? I can't find that answer. The wire runs are not very long either. You would have to compare and measure three identical cartridges just with the different wires. To my knowledge nobody has ever done this.
Schroder offers his tonearms with either copper or silver wiring. I chose the copper. The tonearm wires are scary fine. They look like they would snap if you sneezed on them.
