contempt prior to investigation either impedes or outright prevents, one from the discovery of truth.
Silver is not something to be scared about.
There's more to a cable than the materials. The whole of the process can allow for a silver wire to be quite the thing for a system, now and then, if not entirely.
It's easy to see or find various viewpoints alluding to silver as being zippy, zingy, thin or bright sounding, yet I've found this not always, if at all, the case.
The devices to which any cable attaches play as large a part in what sound is recreated as does the type of metal in the conducting cable, it's dialectic, and terminations.
Dismissing such 'made' cabling is like cutting one's nose off to spite their face. I've found generally speaking, I prefer a mix of copper and silver more often than not.
Truth be told here, purely silver conductors are not the norm in cabling. usually it's a silver over copper application instead. 100% silver, end to end including termination, I've not yet tried or seen. Albeit, there probably are some around... somewhere though I'd suspect them to be quite pricey too.
