You know you're an audiophile if--

Your partner says they are feeling 'horny', and you immediately look to see if they are touching your beloved speakers.

Hearing from your ex-girlfriend, "there is too much stereo stuff in this room--I really like those little Bose speakers" was a tipping point in your last relationship

and

Telling the current girlfriend "you can dance in between the speakers all you want, but please put down the beer cuz you are waving all over the amps", which she turned into a tipping point

Life is complicated sometimes.

You find yourself at a dinner party explaining why some people prefer the sound of records to CDs.

when you are several steps into 'quitting the spending'

and that making a new power cord or new tubes for a few hundred is not really a purchase worth worrying about

Even though it was an upgrade, you kinda wince when you see something you used to own for sale here by somebody else. But then you are happy someone else is enjoying the gear you broke in.
