Bit of head-fi history, as I loosely remember it:
Edwood was the 1st head-fier to 10,000 posts (2004-ish?). Back in the day his thing was Hamsters and the Sony MDR-R10; I think he also used a Grace amp for a while. Jahn was the 1st to 20,000 (2006-ish). His thing was the "tower of power", a Grado HP1000 with I think a Melos SHA-Gold amp (Maestrobated?). Jahn dropped off head-fi soon after 20K -- apparently he sustained some hearing loss from an illness, but he dropped by some years later to let everyone know he was alive and otherwise well.
Both of them were nice to have around, and actively positing, especially edwood. I can't imagine a 55K+ poster wouldn't get annoying quick, though.
