Audiophiles aren't just about dumb stuff of this sort though. The majority of the community is mainly interested in things like trying different speakers/headphones and listening setups, where there are measurable differences and what one prefers entirely subjective.
For me the lack of understanding that it is subjective is part and parcel with being an "audiophile" - I like the "sound" of vinyl, the difference between me and the audiophile religious I know is they'll tell me I don't just "like" it, that it's objectively better and they start saying nonsense like we're reading in the posted thread.
Comparison is the thief of joy, and the only thing audiophiles do is compare.

It may be true, but the audiophile in question didn't bother to do any blind test.
And I believe that actually most of the audiophiles don't do any blind tests, otherwise they'd use twisted coatangers as cables and save themselves a lots of money.
