I've been on Head-Fi for years, and I've always gotten the impression that they're pretty much the same demographic as most other audiophile type forums. I think a lot more 'young people' are into music than are into gear. There are always exceptions, but most headphone reviewers I've seen on YouTube are well past being 'young people'.
Head-Fi can be so hardcore
I was going through the IER Z1R thread on HF and the lengths some people go to to squeeze every last bit of sound (pun intended) out of their stuff make my eyes water.
To each their own but it seems like some (many?) people use music to listen to their gear, and I wonder if they even enjoy music or is it just something to justify their investments...
OTOH, reading that thread does make me wonder if I'm underutilizing mine, now I have to guard myself against bad financial decisions...
