I tested this myself as a skeptic, just changed the cabels, but was able to hear a very clear difference with my ears. Although I couldn't explain that difference as I lacked the vocabulary, still do.
Maybe the testing criteria can't capture that difference either. Either way, you should do you own testing and figure out what you like since this is subjective.
Edit: the scientific method is to test for yourself.
Edit 2: I don't care if you downvote me, but if you refuse to test things like this out for yourself I am disappointed.
