Lmb: By this point in the dialogue one side or the other usually gets snippy, and the other side leaves in disgust. If we keep up with this civility crap, we could bore ourselves to tears.
Training is essential in valid audio tests, although the type of training isn't necessarily what you pick up at the local audio salon. And I suspect the variation in hearing between audiophiles and non-audiophiles is smaller than you think it is. Absent data, we'll just have to agree to disagree about that.
Or...somebody could get some data. I'm not up to it myself, but someone so inclined could do a DBT of cables using a state-of-the-art system and the best audiophiles he could find. You'd think somebody would have an interest in proving us narrow-minded objectivists wrong.
As for your reported positive test, I'm afraid I missed it. Please provide details, or a specific cite.
