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)
