My audio fingerprint?
treble= and bass+
+ 
Now I just need that last one to become a reality...
For the time being (with what's available), I suppose I could say it's treble= and bass+.1 -- thanks to the pin-in-the-bass-port trick.
Oh yeah, the other stuff: I'm usually running my SA6s unamped out of a Rockboxed Sansa e280 or a TrekStor Vibez, with flat EQ. I wear them hanging down and (typically) clipped to either my shirt or the strap of my messenger bag. They're my favorite public transit headphones to date.
