Generally speaking, frequencies up there aren't very important to catch the musical message. What these frequencies do for me is that they make the music more detailed, imaging becomes sharper and soundstage seems more pronounced.
I even feel that headphones with a lot of treble have a tendency to distract me from the music by putting focus on detail and soundstage. Not all headphones do this, but there is a distinct tendency for me.
I've prepared a small example with only frequencies beyond 13 Khz:
"13 Khz and beyond" example
The original song contains an electrical bass, a drum set, a singer (and background singers) a piano and an acoustic guitar.
The original file is of course FLAC as well, just to make sure no frequencies are cropped during the encoding process.

What irony, the AT AD2000 air series doesnt have top end air

May I suggest another phone to try then: the ATH-W2002. It really has a lot of sparkle. Of all AT I've owned so far, it's the most active headphone beyond 10 Khz, which makes it very detailed, sharp (in terms of imaging) and spacious sounding. It won't have that Senn typical mushy warmth, even though its kick- and low bass is everything but lacking. Its midbass just isn't as pronounced, but it still makes me hear some bass texture that doesn't even become that apparent with the L3000.
