Where are the young audiophiles?

We are here, and, on other platforms mentioned above. Vintage gear blended with digital says it all. Your generalization also only applies to US demographics. 

I’m 45.  Just a baby. Some of the members on here remind me of less cool versions of my dad. Not exactly appealing discourse for younger minds. Also, you need cash and space for this hobby. It generally takes a few years to get both. 

Old dudes rule!

The disease of audiophilia is an expensive one. Young folks don't have the coin to play this game. 

@jundaku - I think you're on the right track.  It's hard to really get into the true audiophile level gear until later in life when you hopefully have more disposable income.  I'm a 43 year old family man and over the last 15ish years have purchased more audio gear that I should have and I'm still playing on the low end of things.  I'm currently into the game about $10,000 in round numbers including a  home theater receiver and two stereo integrated amplifiers.  I think that the audiophile world is likely always going to be primarily supported and "financed" by the older generation.
