But I can also believe that it is at least somewhat different for audiophiles. I once took a beer judge certification course, and, by the end of it, I could easily distinguish flavor subtleties that were completely imperceptible to me at the start of the class. Not just in a "I think I can" way, but reliably in blind tests. And I've had a similar experience of imperceptible differences becoming easy to spot when learning to speak new languages. So it seems possible to me that simply being an audiophile makes it possible to care about subtleties that non-audiophiles can't even hear, because brains are magical like that.
