They're used, so I'm pretty sure they're burned in. I've used dark sounding headphones and IE's like Koss and Sennheiser in the past, so I think it takes some time getting used to the Grado sound. Having said that, I love the 225's so far. I listened to some alto sax music today, and it sounded incredibly airy and lifelike.
Thanks for the info on the amps. I tried the 225's on my Creative Zen today, and to my surprise, the MP3 player was able to drive the Grados' pretty well, so I'm starting to think that buying an expensive amp is unecessary. I'll see if I can audition a headphone amp at one of the local hi-fi stores. That's the only way to find out for sure.
