Buconero117, I don't see the need for audiophiles seeing an audiologist just to see how "broadband" their ears are. That would be like spending a lot of money to get harmonic distortion numbers on my amps - there's a lot going on in the process of listening that test tones don't tell you anything about. The important thing is how you experience music, and if I was told my hearing stopped at 8 kHz, that would just make me feel older and accomplish nothing else.
Everyone gets to decide how much they appreciate music, what kind of gear and set up is worthwhile to enhance the experience, and how obsessive they want to be about all of it.
