Thanks for this!
I'm thinking the HE-500 probably sounds like a good pairing then. I really wanted to try the LCD-2s, because I heard they had a really silky/smooth natural sound. And to me, that sounded less fatiguing. But if the bass is really a hard hitter, it could fatigue me.
Thanks for your input on the HD-800. I think I'll pass on that, because a lot of the music I listen to will probably sound like ****. While I do listen to a lot of classic rock, I also listen to a lot of modern rock (especially Indie). And a lot of the mastering/recording is awful. So I can only imagine the HD-800 would obliterate my library.
The bass on the LCD-2 isn't what i would call overwhelming, it's just that it extends really nice and deep without much roll-off. It's definately not overbloated or heightened at all in my ears. Of course the best course of action is to try and find a shop to try them in, and since I assume you're swedish (reading your avatarname) as well I think there are some shops in stockholm that do carry them if you happen to live nearby.
The fit might not be for everyone, it's a heavy headphone but the sound is rather excellent!
