ATH-W100 very recently. I would never have known about these otherwise. Also, I purchased my Ety ER4s canalphones solely due to the rave reviews that I read on headwize a year or two ago.
I had an HD-600 long before I discovered head-fi and even before headwize I think, but I am a long time Sennheiser fan starting in the early 90s with my first $200+ headphone. I was also a porta-pro/sporta-pro/ksc-35 fan long before I discovered any headphone sites on the internet. My very first non-stock headphone was a Sony MDR-V6 in the mid to late 80s. I paired that puppy with my Sony D-10 PCDP and took it everywhere.
had my trusty 7506's since i was in high school. then last year my bro told me to read the stuff here and i bought the hd600's and a MG Head. the mg head was a mistake (the one i have now works great... but took more than one year of hassles to get it)... but those hd600's sure sound good.
had er4p's before coming to head-fi
first i needed excercise headphones.. sportapros
then i needed full size comfortable closed headphones... dt770's
i think i'm okay with headphones.. sometime in the future i'll get a top of the line closed (w2002 or cd3000) but i really need a good home amp and a good source
yeah.. some people don't agree that cd3k are closed.. i just care about sound leakage
I think after a week, a high end meta. Then maybe the next week, some SignalCable IC's. Then maybe 2 weeks later the Xfeed. Then some Zu Cable IC's. Then the SR-225's. All within a 2 month period I think. Oh yeah, and then the iRiver IMP-550. Which reminds me, time to update the profile!!
Beyerdynamic DT 770 Pro (250 Ohm), in July 2001. Audio Technica ATH-W100, January 2002. No new headphones since then. But I have bought power cords, interconnects, NOS tubes, a mains block, a CDP, a demagnetizer, a second headphone amp. One has to keep oneself happy, right?
