I'm of the mindset that the HD800 probably scales higher than any other headphone out there. Mainly because they are the most detailed, most neutral, most transparent headphone out there. They are also highly sensitive. I'm curious where their ceiling lies-because it doesn't seem anyone has reached it yet...ie, the HD800 is never the weakest link. I don't include Stax in that statement-because there simply isn't a ton of gear (ok, amps) to choose for them. Not sure where the LCD 3 fits with all this-but with most comments here, they seem to be the most chameleon-like headphone around, moreso than the Audeze or pretty much anything else.
