I can actually "hear" ~35-18 kHz (I've tested), but for some reason this doesn't bother me at all. There definitely is a spike that lasts about ten seconds at around 16kHz. Interesting. RazorJack has super sensitive ears i guess
BTW, be protective about your hearing, you'll certainly miss
that when it's gone *daddyspeak fingershake*
I don't personally play music at high volumes at all, especially with headphones, except when drunk

I just find it disturbing.
Inspired by the few last posts, listened to E4 while falling asleep. Last stuff I downloaded was some Lustmord remasters and Woob: "The Six Hundred" which is some old stuff ran into a very old R2R tape. It's ok, actually has some pretty good tracks.
