Goodness, this ought to be so simple.
A bibliophile is one having a disciplined appreciation of literature
An oenophile is one having a disciplined appreciation of wines
So an audiophile is one having a disciplined appreciation of musical recordings
You're not a true audiophile unless...
I can't tell you the number of posts I've seen that start with something like this. Why are some people so anxious to qualify this like it's some sort of title? Being an "audiophile" isn't a concrete or objective thing like the citizenship of the country you were born in or being an MA. It's reflective of your hobby or taste, much like calling yourself a "foodie." Can anyone else chime in with some of the more ridiculous qualifications people have come up with for calling oneself an "audiophile?"
