Dont forget that the 3 cables you compared AN, Cardas & Discovery are vastly different constructions - AN is a 3 wires litz per conductor, Cardas is a multistrand variable size litz, Discovery multistrand uniform size ( not sure if true litz ).And of course the insulation is different on all three cables.
FYI - a few years ago I put some Furutech La Source 101 headshell leads onto my FR64S. This was one of the biggest surprises I’ve had in many years. I have been in top end audio for 30 years sold multitudes of top arms and rewired plenty.
I note that their cartridge pins are rhodium on phosphor bronze - they are exceedingly tight and I would check out if you can source some of those pins. I agree if you are using the AN wire the AN pins look very good. I like the crimped construction.
The coils of the Rosewood Signature Platinum are made of 6N copper wire, painstakingly clad with a silver jacket.
So what - I have a Dynavector Karat Nova 13D and Ikeda Kiwame both of which have copper coils and piss all over the Koetsu Rosewood Signature Platinum for transparency and speed.
I have not analyzed that from a mechanical perspective. Both metals are very ductile and malleable. Wires of similar gauge will be just as flexible.
Nonsense - copper is far less maleable and harder than silver given the same size etc.
