Not piercing highs, it depends on the frequency of the highs. Example grados have piercing highs when using bowls but they are low frequency highs and they dont contribute to the soundstage. It is very frequency specific, not just about random high frequencies.

I don't really agree w/ all the talk about frequencies, as I always EQ my cans to kill the treble resonant frequencies...saying that a wide 3D SS requires piercing trebles couldn't be farther from the truth.

the Smyth uses top range DSP, some sort of tailor made "Dolby Headphones"...like what Beyer did: http://www.soundonsound.com/sos/mar07/articles/headzonepro.htm
 
It's even got a tracker to know the inclination of your head

 
I was talking about a "passive" 3D SS...and I'm not really looking for room simulation tbh, I just want a wide SS on 3 axis simultaneously..not just a boring L/R.

Even if you don't want room simulation, you'll still need some kind of individualised HRTF processing to achieve what you want. There are no two ways about it. Moving drivers around, angling them and changing the size or material of the enclosure simply can't produce 3D sound like you hear in real life. Even the K1000 doesn't come close to that.

someone in another thread said that all headstages were FAKE...so maybe, I dunno...I need to chew on this, I'm not quite ready for the idea that what I'm hearing is fake.
 
I'd hate to quote myself, but on the cd3k every instrument has its own micro-SS within the headstage...it comes from somewhere huh: http://www.head-fi.org/forum/thread/418746/the-beyerdynamic-dt48-arrives/1890#post_6653364
