Honestly I can't remember a time when I wasn't an audiophile of sorts (at 7 I could tell that the CD played through the car stereo sounded way better than the same song when it played on the radio, and I had the most trouble trying to get across my meaning to my parents, who evidently can't tell the difference).
Seriously, my true audiophile journey began when I picked up my first semi-decent kit, which was a pair (actually, two) of those Insignia bookshelf speakers everybody raved about a few years ago (I know, I speak blasphemy on a headphone forum--I'm over at AudioKarma, too). Paired with a vintage receiver, they make nice noise. But I wanted to upgrade my headphone listening experience in kind, so I searched around online...
...and found this place. I've been lurking for almost half a year and finally joined up when I got my DT880. I guess the thing that really got me into this racket was the relentless pursuit of fidelity, and the fact that I love sound almost as much as I love music. Good sound is like sipping on a rich milkshake in whatever flavor you choose (just pick the song). Everyone I know thinks I'm nuts, and sometimes I wonder what it would be like to be blissfully unconcerned with fidelity. Sometimes I envy the people who shove those white earbuds in and just drift away...
...then I flip off the lights, slap on my cans, and cue up one of my favorite albums and forget all about those doubts.
