FWIW, IMHO, the differences between 'standard' design cables is more about how you percieve them than any thing that spec's can predict. I would recommend that you try to identify cables that are benchmark in the price range you can easily afford. Then when angst sets in about system improvement you will have established a reference.
I consider the Cardas 300b IC and Canare 4S11 speaker cable to be outstanding in their price range and a great place to start out (or even finish, if you are so inclined).
