Is being an audiophile a disease?

It's called GAS -- Gear Acquisition Syndrome. It is rampant in other industries as well -- or else, I wouldn't currently own 57 F-mount lenses and 10 F-mount bodies (not to mention all the ones I no longer own). There is always something that is just a little better or a little different that might make a big difference in the outcome. Expensive cables, anyone? Yeah, right.

Well as best I can tell it’s not normal.  But normal is boring. So is average. 

Gear Acquisition Syndrome

I consider myself an audiophile precisely because i dont buy anything....

First off, the delusion of perfection or authenticity ought to be dispensed with. It is the utmost in foolishness.

But to seek improvement and novelty--what's wrong with that. We are wired to seek new experiences, and so much of human society is dependent on that drive. 

We tend to mock the foolishness in other people's hobbies or interests, while being endlessly fascinated by our own. Just the other day, I smirked at someone who dislikes the American president, yet invested time and money to read his nieces account of Mr. Trump.

But why should I smirk? It is no stranger than me drooling over high end tonearms that I would be foolish to acquire. 

YES,but at least there's no chance of dieding from it.  But ,You may ended up in a mental unit.
