Thank you for your valuable info! Unfortunately, I do not have an option to measure LCD-3 myself so I can only use measurements available here... Do you think your LCD-3 is the veiled, or unveiled version? They should be different in their responses...

Innerfidelity's Rev2:
I would say both Audeze phones are fairly neutral... HD800 do not have flat bass by any margin and their treble is also not neutral. Mids are allright. HE-6 have too much treble and the bass is also not ruler flat.
Also, I am free to EQ my pair to neutrality very easily as I have the measurement available with me... I have my EQ curve already done but prefer their natural response for my rock and metal music so far. But for more critical listening, I have it ready!
This is also why I don't think Audezes are only an audiophile phone... You get the graph, this is very rare. Lunatique prefers Audeze over Staxes so far for their sound even for professional work (neutralised by EQ, of course)... That's interesting.
