I bet a generalization of audiophile people in this matter, is very impossible. I've met audiophiles who spend more time tuning and balancing their equipment, than actually listening to music. I've also met audiophiles who just want to listen to music the way they think the music should sound, and they tend to spend far more time listening to music, than researching and buying and tuning gear.
In my case, I'm only a little audiophile, and mostly from necessity. I make music myself, and I enjoy a wide range of music styles. Visiting an audiophile friend, I was extremely surprised to discover how severely bad my own setup was - and this last 1½ year, I've been constantly upgrading and refining my stereo. This taste for a more finely produced sound is now also obvious in my choise of headphones, and I distinguish very hard between monitors and speakers/headphones that are meant for listening music.
