I would like to know from a technical point of view why silver wire sounds different from copper. If not, why is silver used so often in audio applications.
For starters, silver is 8% more efficient conductor than copper. That means it's faster and is capable of more extended bandwidth. The extended bandwidth has at least two effects: 1) Rise time of all waves are at least 8% faster. This rise time difference has an effect on everything, especially the leading edges of notes and how quick and fully formed they are. 2) Whereas cupric oxide (oxidation of copper) functions as an insulator, silver oxide (oxidized silver) is at least as efficient a conductor as silver itself. This means that silver wire's conductivity and speed should remain intact as the metal ages and oxidizes. As copper oxidizes it gets worse.
