When I hear of someone who claims to have "golden ears", I immediately think of those who imagine that their ears are more capable than test equipment and actual measurements, but who absolutely refuse to put their supposed abilities to an actual test, in which they cannot see what it is that they are hearing, using their eyes to distinguish between things, all the while yelling, "trust your ears"! Frankly, there are too many people who make all sorts of claims, but never back them up with anything like evidence. It is much easier to pontificate than to demonstrate, and most will take the easier course.
