Silver is the best natural conductor on earth in conductivity i.e Electricity/Heat.
It is only surpassed by some super-conductors in resistance, once they are held below freezing point.Then to have these properties in normal living conditions it's not an options, unless in outer-space etc.
We make the silver into wire all in-house, to the sizes, and to our own designs.
The result :- Lustrous, mirror like surface upon the wire, as audio signals try to flow on the outside of a conductor, not through it's centre.
This is very important.

Picture is of a three year old cable see how shiny it still is!
