There are no rules that apply to everyone, whatever sounds best to you. Everyone has different gear and tastes and what sounds right in one system may not sound good in your system.
I own silver & copper ICs and silver & copper speaker wires and mix and match them all the time depending what gear I am using and what sound I am trying to attain.
Then we have AC cords........another variable.
