Since the cable interacts with the speaker at one end and the amp at the other - and it is these interactions which largely determine how it "sounds" - how is it even theoretically possible to make an "objective" evaluation apart from the devices it is connected to? Aren't the only "objective" things you can measure about cables inductance, capacitance, and so on? Things that may help predict how they will interact with other devices (or may not; too many variables.)
Can we objectively rate speaker cables?
I'd like to generate discussion to compile some sort of chart that compares cable attributes. I realize that cable attributes will vary by system, but I would think that in the same system, certain generalizations can be made. For example, I think many would agree that copper is generally warmer than silver. That said, I propose the following categories. Feel free to add categories to make this a mutually-exclusive, collectively-exhaustive list and/or offer ratings for cables you've auditioned.
A. analytical/detailed (1) - warm (10)
B. closed soundstage (1) - open soundstage (10)
C. slow (1) - fast (10)
