Good choice though my friend. The HE500's are definitely the best for classical between the two. I'd be more than happy to only have the HE500's if all I listened to was classical.
My LCD2's are keepers for my love of Jazz, and they can't be beat for this genre. No matter what anyone says. I won't believe them. Simple as.
I have no complaints about the HE-500 with orchestral material. With the pleather pads out of an HT receiver playing 256kps MP3s they still frequently remind me of the real thing. My main complaint is comfort. They squeeze so hard it reminds me of headlocks back at school. (Ah...nostalgia )
