one often overlooked "problem"

John, thanks for the link below on the metals.

Since we are talking here about tonearm wire and since most of the silver used is solidcore wth teflon it is necessary to use a much smaller gauge than say the 33awg Cardas Litz wire. From experience one must use about 36-38awg solid silver to gt enough flexibility for use in a tonearm.

33awg copper has a resistance of 0.676 ohms/meter. To compensate for the better resistivity of silver add say 6-7% or let's say 0.723ohms. That is "just" 34awg of copper. 38awg copper is 2.19 ohms/meter so silver would be about 2.05 ohms/meter. 36awg silver is 1.22ohms.

So in general if it makes a difference, the resistance that is, a suitable (from a mechanical point of view) siler would be 2 to 3 times the resistivity of the 33awg Cardas litz wire.

And I personally have not been able to hear the "magic" of silver in trials using the same gauge silver, silver plated copper, tin plated copper, tin plated silver and pure copper. These were all 30awg used as interconnects.

Cheers!
