Back on topic, FWIW, I think the alleged diffreences between the sound of copper and silver interconnects are over-stated.
When silver wire was first introduced by a few manufacturers, they were given a stereotypical sound by members of the audio press and early adopters (i.e. "bright, brittle, and thin"). This pre-conception about the sound of silver cables vs. copper cables ("warm, fat, and rolled off") has carried over to today in an almost caricature-like way.
But this initial observation was based on a few early samples of silver wire, and back when even the fanciest copper cables were nearly as sophisticated as they are today. Nowadays, there are plenty of examples of silver cables that "don't sound silver" and copper cables that don't sound like copper. A cable is far more than the type of metal used for the wires; they are the sum total of all the design choices, materials used, geometry selected, dielectrics used, shielding (or no shielding) used, connectors selected, etc.-- they all have an impact.
Nevertheless, do I think these metals have some sort of inherent sound signature? Yes. Given a choice between two identically constructed cables, one with copper wires and one with silver, I will choose the copper cable every time. However, given two totally different cables with radically different designs, knowing whether one was silver or copper would not help me much in my decision making. I would need to listen to both.
Another thing-- scarcity on planet earth, and arbitrary value placed on certain metals by people who like bright shiny objects does not mean one metal sounds "better" than another or is naturally a superior conductor. It does not follow that because gold is more expensive, that gold-conductor cables automatically sound better than silver.
Use your ears and listen to the whole cable, and worry less about what kind of metal is being used, you may be surprised by what you like and don't like.
