I used to hang out at Head-Fi a lot in the early ‘00s. It’s a headphone and headphone accessories (amplifiers, DACs, etc.) forum, and people nerd out about building their own stuff. I recall writing a review on some obscure Chinese brand of sound card that people liked, because it happened to have a really good DAC for the rear output (it was a surround sound card, back when that was something interesting).

I gradually lost interest when they started heavily pushing commercial sponsors. I get it; sites aren’t free to host, and moderator time isn’t free / unlimited, but it’s still sad.
