Headphoneus Supremus
It's all right up there - all from my own listening. No exact measurements, none of them to scale to the size of my head with actual figures. All only by dead reckoning, basically more of a qualitative than a quantitative representation of what the soundstage is like, top down (where it's easier to see all that rathr than use a 3D model from my POV). Despite all that, it's a quicker way of getting what they sound like across to another person rather than typing out paragraphs. Also there are more drums than in a typical drumset there for two reasons: some of the songs I used were progressive metal (which might actually have more than seven) and second it is more a representation of a rough curve where (which isn't one smooth arc, as seen in the more "W" shape in one diagram) the drums generally would be.
If I were talking to someone in person I'd be using my fingers and placing them where whatever I'm pointing to seems to come from. I'd take measurements from where my fingers are, but then again you can see I'd rather do a quickie Paint job than do all that, more so because it's not for nitpicking whether the HD800's stage is how many inches larger than the K701's in every direction
In any case, those measurements would not be as easy as one thinks - I'd have to use for example some point beyond the skin on my head as reference point, then measure not just the distance to all other points but at what angle, etc. Anyone who might have access to equipment like that should do it though, like some kind of laser system (like what law enforcement uses to track bullet trajectories at crime scenes, I suppose). The problem at that point though is that every person might have a different measurement of it, and I'd bank on many who might hear something similar from the qualitative desciption but then everyone of them ends up differing in the minute measurements in the quantitative measurements, rendering them unnecessary. That does not mean, for example, that this can be relegated to purely psychological effects like testing modern tubes vs modern SS amps with one control group then another group doing the same thing blind, only that the general description suffices in the interest of dicsussion and actual measurements already unnecessary (given everyone has a different head size, for one).
