I understand the guy in the original article's point, and yes Audiophiles are an obsessive bunch, but then so are ambient fans, jazz fans, goth fans...basically anything we claim as "ours".
Thing is, it is OK to be an expert at something. Its ok to know more about jazz than someone else and be an expert. Its ok to know more about and appreciate ambient music than someone else. Its ok to devote your time and money to the best sound playback in the universe and train your ear to hear detail and nuance that others do not, the same can be said for a somallie (pretty sure I spelled that wrong...you know professional wine guys), its ok to be a foodie.
Here is the thing, the balance is A: Don't be a snobby jerk about it, but B: if you are not one of the above, don't get defensive when someone knows more about something than you do, remember a persons opinion is never more valid than true study and expertise. This second part is a real problem in the world of the internet of instant opinions. Its almost an anti-snobbery, snobbery.
Now on the subject of audiophilia...yes it gets crazy. Many of these guys have playback systems better than the gear used to originally record the music.
