Thomas Edison would have had a good laugh at the remarks of the "golden ears" crowd ...Nonsense. Edison believed in hands-on experimentation - that was instrumental to his success. It's highly unlikely that he'd sit idly by, proselytizing theory from the comfort of an easy chair while others actually reported first-hand results. You might want to visit one of his museums sometime. It will give you some practical insight into the scientific process. Mind you, it can be a tortuous process. That's why so many of the measurementalists here avoid it like the plague. It's much easier to just preach.
