This place is awesome, it started at exactly the same time I started becoming obsessed with headphones. I forget why exactly, I think it was a buget issue, I couldn't afford speakers anymore.
Less than a month after I came here, I got a pair of HD600s from Jan Meier (he is the man by the way). They've been a dream ever since.
Less than a month after that, I got the OBH-11SE from some guy in Sweden or something far away like that for $200, not bad considering it included a pair of Grado SR-60s and some $50 interconnects.
Before I came to Head-Fi, all that I had ever used was the CHEAPO headphones that had come with my Sony discman, so this place has certainly been an eyeopener.
And then most recently, it's been the Etymotic ER-6's which I also love.
As far as the future goes, I want a pair of kick-ass closed phones, so I'll probably be placing another order with Jan Meier for a pair of Beyer's, haven't decided on the model yet, although a pair of ER-4's might become a reality before then, I love my iPod.
