That would not make sense as people do not want to read about objective evaluations, they want to decide themselves what to buy based on another's ears and preferences...
Actually MHOE, I think Jude was being tongue-in-cheek. Of course it isn't possible to review headphones you haven't heard based on measurement alone.
FWIW, I tend to agree with you about the HD800. Ultimately no matter what one person says about a headphone, no matter how good his ears, you have to take the majority concensus, and that says that in most situations, with most equipment (ie, affordable stuff), and with most recordings in most genres, the HD800 is a little too bright and analytical and simply not forgiving enough for consistently enjoyable day-to-day listening. I've never heard it: I'm just saying that that would be my judgement were I to be considering phones in that price range. And unfortunately, that judgement would be bolstered by the FR. Combined with the myriad comments here on Head-Fi and elsewhere, that 6-7khz peak would really worry me.
I'm not saying the HD800 can't be got to sound relatively flat and neutral and--who knows?--maybe even slightly warm. Just that the evidence suggests it isn't likely in the majority of situations.
