At what price is one considered an Audiophile.

I know of this site, starts with an A where this subject has been debated so many times....

When your mate leaves and you don't even notice.

It's a mindset. I was fiddling with a suitcase record player jacked into a musical instrument amp and PA speaker when I was a teen. I have progressed since then. 

There's a darker view of self-professed audiophiles for whom "source material" is meant to demonstrate the virtues of the system. That, to me, has nothing to do with music. 

I don't view this hobby as an exclusive club. The boundaries are limitless in terms of accumulated knowledge and know how. 

At what price?
That of your soul.

All the best,
Nonoise

How long is a piece of string?

It's all relative.  Some gear out there I dream of owning, some Audiophile gatekeepers, call it "midfi."  While my humble system would be an audiophile system to regular folks or those that are just entering the hobby.  

You could have a $10k pair of speakers and someone with a $50k+ pair of speakers might call those speakers beginner or midfi.
