Because aural memory is short, and fraught with personal bias issues, unless you can make cable comparisons in your own system, over a reasonably long period of time, you are mostly just pissing in the wind. Of course, cable manufacturers are going to tell you that you are missing out on the “magic” unless you have a “full loom” of their cables. IME, that is just marketing baloney. Try different configurations of known, well-constructed cables and use what sounds good to you in your system. You can read a lot on these forums but IME, 10% of system cost is a good “ballpark” goal. Go much higher, and a component upgrade will probably be a better value. Also, for the best value, try and buy used. Once they leave the store, cables are worth about 50-60% of their original cost.
