Two things I have noticed:
1. Typically all pure silver wires I have heard till date alter the tone and timbre of the instruments.
2. Cryogenic treatment of wires also makes the sound tad dry and lifeless, less micro details as well.
I am waiting for at least one exception.
I apologize if this was not very helpful for the original poster but since both the things are related to un-musicality so I could not resist writing it.
