If you prefer listen to music on excellent studio monitors that already makes you more discerning than 99% of the general public. You could very well apply the label audiophile to that, no?

Maybe we need two words, one for people like you and me that care which speakers they listen on (because for most, whatever small bluetooth speaker is at hand will do), and one for the people that buy $500 cables?

BTW I feel everyone is affected by differences in audio reproduction. Like how much you can get into a the music at a party will be affected by the sound quality, it’s just going to be subconscious for most.
