Thanks @gepardcv for pointing out oratory's 800 (non-s) setting. After googling for a while, I got this: https://www.dropbox.com/s/6czdp06yd7bzvb7/Sennheiser HD800 (5 Band EQ).pdf?dl=0 (prol this is what you meant) (For simplicity I am calling 10B 800S setting Oratory1 and 5B 800 one Oratory2) While Oratory2 sounds a little better than with 1. Still sounds a bit rougher in the upper registers (both ora1/2 are rougher than stock 800 in the treble). Needless to say, I still hate harman bass. Likely harman guys, study participants, HT-advocates, and HT-lovers may "perceive" 800 as extremely bass-shy. That's not for me at all. My reference of "just right bass" is the closest to LCD2 (and 2 classic), rather than Dr Olive's work. And this is highly correlated with sbaf-compensated flat response in entire bass (20-200hz). While there may be some benefits of harman's "perceptionally preferred" bass levels, I will neither like it nor regard it as "neutral" any day. And both subjectively and objectively to me, hd800 is not bass-shy or bass-light. Ignoring its' upward tonality, the real problem against neutrality is midbass hump. This seems to occur in most dynamic drivers with open-back structure though.
