So it appears there is no way to set up a "scientific" test test that will make everyone happy audiophiles will be debating this for the rest of time.............
But what about doing something simpler? Just prove to yourself which cable is best for your system (blinded). Have a friend swap the cables for you and you listen and decide what the differences are. If there is an audible change it should be obvious without you having to look at your friends face to try and cheat and get a clue. It doesn’t even have to give a statistically significant outcome. If you tend to like one over the other that is the cable to use.
This test would be best if you have some different demo cables to pick from. After you already spent big bucks on a cable it will be more risky. Its not fun to find out you like a cheaper cable but like everyone said cables are system dependent. There is no reason a cheaper cable might not sound better. Also, this test will not prove anything to others, It will just give you more confidence that you picked the best cable for your system. Regardless of cost, how fancy and thick it looks, or biased audio reviews.
