I'm a long-time casual headphone user who picked up a cheap pair of HD 598s on a black friday deal several years ago and who recently resolved to spend at least a little time each day doing mindful listening. I found some great information on equalizing the 598s from @stellarelephant here on Head-Fi, and it's really changed the listening experience for me. So, I figured this is a good place to get more involved and contribute back. On that note, I've got some interesting iPod Touch measurements to share. I couldn't figure out from the posting guidelines at what point I'll be allowed to start new threads, can anyone shed any light on that?
