I have a pair of Grado SR80i's that I listen to at work and I love them dearly for 90% of the music that I listen to, but as many people say, they don't quite cut it for classical symphonies. Personally I think that the issue has more to do with their lack of body and impact rather than their small soundstage.
The other day I listened to some classical through a super cheap pair of IEM's and I think that I might have stumbled unto something. The increased "blackness" from the isolation made the whole experience much more involving for me. It also made the dynamics seems much more... um... dynamic. I didn't really miss anything from a soundstage perspective.
A pair of closed phones wouldn't hurt to have at work either. I thinking about trying either the Shure SRH440's or the Beyerdynamic DT770's for this purpose. Do any of you guys have any experience with phones with classical or any take on closed vs open for classical?
