At what price is one considered an Audiophile.

There is no $ amount as a price of admission.

For me it is about the rush I get when I hear something new or different in a record that sounds better. At times it may be from a minor change that has big impact or a relatively bigger change that may only has a small impact.

If you appreciate reproduced sound quality, seek to have it in your house and realize you can always get something better and can live with that you are a sane audiophile. If you are on the never ending hamster wheel of upgrades, my condolences. At this point, I am happy with my system's sound and realize the limitations of my room acoustics and only change equipment when something breaks or wears out. 

I do seek out better sounding records of my favorite recordings however....luckily that is a fairly reasonable number. 

You are an Audiophile when

You wake up in the middle of the night to turn over and start thinking about

Toeing your speakers in or out.

If you should buy a different power cord

Should I put more absorption on the back wall

Should I change the hollow core door to a solid core door

It has nothing to do with the amount of $$$

gotta have a solid core door

An audiophile is person with the pursuit of reproducing music as faithfully as possible by using hi fi equipment... Budget has no bearing. However, the pursuit can be quite expensive.
