The csd of srh940 actually can be also read as high treble presence (high peak, slower decay) without being covered by mids/bass (which the hd800 has, in contrast). I wouldn't say its better, some may like, some may not. Btw the bass response of hd800 definitely looks and sounds better to me
I've listened to some piano on the srh940, which is supposed bass lite to avoid the supposed muddiness in the region below 500 hz. I found it's a delight to listen, it's relatively clean, BUT the hd800 is much more precise, with each note being very well defined.
I'm not anymore experimenting the skull crushing treble spike, I got when I listened the srh940 for the first time, so you might have in mind something quite different.
By the way, what you think of the mdr sony mdr-z1000 (it's on your profile) . It measure consistently bad everywhere, in particular the csd that looks like an exageration of the srh940 (similar flaws, but worse). I'm wondering how it could have fans , according to the measurements.
