On two different occasions, I've read articles by a very famous audiophile who claims LPs sound better than cds, who said something along the lines of, "I really liked how this xxx sounded but I haven't seen the measurements yet so I could have egg on my face." If you like how it sounds, measurements don't matter, but don't try and convince me that it's better than something else.
I figure subjectivists are like religious people and objectivists are the scientists. There is no proof that a new cable, silver fuse, etc improves the sound, but they believe it does As @djones51 said, until you take vision out of any audio testing, there's going to be bias.
