Thanks for your feedback, that's a really informative post.
It seems like you and most others who have either owned of tried both agree that the HD 800 offers more in terms of technical capabilities and comfort, and the LCDs providing better "musicality". The LCD 3 is unfortunately over my budget so i won't be looking into that for now, though i certainly hope to own one in the future. As far as i know, you're the first I know who's pointed out the headband getting disconnected and subsequently scratching the wooden cups during shipping, so that's certainly something I'd wouldn't overlook in the event i choose the LCDs. I shall decide on either of these two awesome phones after properly auditioning them, and I'd definitely pay more attention to the comfort side of things since you've mentioned the HD 800 far outperforms the LCDs in that aspect.
On a side note, I also intend to use the headphones with movies. Which of these, in your opinion, would be better suited for that?
I actually watched a movie or two with both... Well, for me, there is no contest - HD800 all the way. The soundstage and precise imaging they provide is impossible to beat. Also, their bass is surprisingly visceral which is most probably emphasised through the excellent soundstaging (near-to-holographic soundstaging!).
I understand that I am at "LCD-2 appreciation thread" but unless you really want a bit dark and calm sound where bass and mids are dominating, I would definitely go for HD800 if possible. LCD-2's strongest point is the bass and midrange, their cooperation, just the frequency response curve itself is what makes LCD-2 as enjoyable and popular as they are. The strongest points of HD800 are soundstage, imaging, separation, microdetail, neutrality... I think you can see the difference.
