At what price is one considered an Audiophile.

An “audiophile” only need be self proclaimed. 

$0. You are an audiophile if you love music, sounds, and notice and appreciate all the nuances you can experience in listening.  Steve Gutenberg knew he was an "audiophile" when he'd spend time just listening to the various qualities of hiss between FM stations. 

Money and equipment are the means to let us experience that which we love, but it doesn't make you an audiophile.  

Audiophile. It's largely an ambiguous term.

Do you like music?

Does what you listen to it through sound good enough to you?

If not, are you improving your equipment enough so that you do like it?

Good enough. Except for helpful advice, nobody else's opinion carries much weight.
