Pure Silver Wire

@worldwidewholesales  posted the following:  "the “charge carrier mobility” is higher on silver than on copper. And this is why silver sounds so different than copper.

Yes, the charge carrier mobility has to be greater for silver compared to copper. Silver has a slightly greater conductivity than copper and the charge carrier mobility is directly related to conductivity. A metal’s conductivity is directly proportional to the following:

1. The charge on each carrier. For Ag and Cu the charge is identical because both metals have 1 free electron in their outer shell.
2. The number of carriers per unit volume. In the pure metals, the interatomic distance between Cu atoms is less than the interatomic distance between Ag atoms. In the pure metals, Cu has ~ 8.43 x 10^22 atoms/cm³ and Ag has ~ 5.85 x 10^22 atoms/cm³. Therefore Cu has more charge carriers per unit volume (~1.44 x more) compared to Ag.
3. The mobility of the charge carriers. The greater charge carrier mobility for Ag compared to Cu offsets its lower number of carriers per unit volume compared to Cu to give it a slight increase in conductivity.

The difference in conductivity between Ag and Cu is relatively small (~5%).

Ag conductivity - 6.30×10^7 S/m

Cu conductivity - 5.98×10^7 S/m

Kimber cables knows how to design silver cable. I have their digital cable D60, kcag ic, and 8AG speaker cables.they match well with tube gear. Onother favorite is Audioquest dragon speaker cables , diamond ic. They work well with tube and ss.

Wire is wire. Resistance is all you need to worry about, so save yourself a lot of money and buy some low cost speaker wire of the appropriate gauge.

Not a single person in this thread could discern a difference in a proper test.  

Even when one one single element of something is rated to be better for some reason, it does not equate to an improvement of the result. Arguing copper to silver is a fool's argument in most cases, not all. Same thing when arguing the heat conductivity of copper over stainless in some uses as in the end of the process the heat exchanged is more than sufficient for the required process. Having the proper gauge copper wire is more important than having any silver. The copper is not holding anything back for our purposes. We can take things to the scientific extreme and argue a lot of BS, but none of the scientific extreme applies here. Proper connections, soldering, and shielding are a much greater value.

Only cable maker I know that offers solid pure silver cables is Timbre Audio.
