But I think Silver also dissipate heat faster (create a lot of loss); and according to the article it is no good for inductor to gain the electrical energy but then converted to Heat energy and loss; The intended electrical energy intended not going to the loud speaker.
This my 2 cents only; still learning
let me send a email to goertzaudio to ask them... but i believe this is enuf.
"pure silver conductors are highly valued by many audio enthusiasts due to their superior ability
to reproduce voices and instruments in their timbres in an extremely differentiated and neutral
manner, and - if possible - are preferable to copper conductors."
