I would consider an audiophile to be somebody who takes home sound reproduction as a fairly serious hobby. They probably have a lot of money tied up in equipment and source material. And further, they are likely constantly looking for tweaks and improvements to the sound of their systems. In other words, fine tuning the sound is an ongoing and possibly never ending process.

And finally, I believe Audiophile City is the birthplace of most of the more far out tweaks like putting your CD in the freezer or lifting your cables off of the floor in the quest for audio nirvana.

I think the part where audiophiles get flak from guys like me is when they try to give a technical explanation for something like putting green marker on the CD improves the laser aiming (and the sound of course) or some other such nonsense.
