Hahaha I sold the HP2s a while ago

You are spot-on Leonardo. This is the best review I have read about this headphone!
Nik call the HP 1000 a musical instrument, the midrange has been described as analog more than once, and someone literally made a thread about it, calling it “velocity”. I believe it is entirely due to a fundamental technological difference it has that all other dynamic transducers don't.
Precisely, something Joseph Grado referred to as a rear pressure diffuser/equalizer (I don't remember the exact term) in a clipping of, again I don't remember which, Audio Magazine in the early nineties. The fact: http://cdn.head-fi.org/a/ae/500x1000px-LL-ae32c08a_900x900px-LL-89ed175b_driver1.jpeg
My crude interpretation: http://i881.photobucket.com/albums/ac14/devouringone3/HP1000-Copy_zps77445b8f.png
And I equate the mellowness of the cymbals to the star patterned vacuum formed creases of the dome (responsible for the high frequencies on headphone driver diaphragms), which are also unique to this driver.
Leonardo if you like your HP 1000 you owe it to yourself to try my mod (I won't listen to my HP 1000 any other way, personally) (it's the second half of my post; bear in mind that English isn't my native language either: http://www.head-fi.org/t/576717/grado-modders-go-magnum/2640#post_9507046
If you already own HD414 pads you know that, stock, they sound neutral, dynamically equal (sound the same at every volume level), detailed/transparent, and bass-less. My mod will increase the bass where it's lacking in quantity and hence improve its extension. You can expect to have easily more than twice the overall bass amount of non-taped TTVJ flat pads; my gross, honest estimation.
Bass doesn't flow through open space (foam is near equivalent to open space) as easily as highs, that's why you need 3M Scotch tape (which properties seem to do bass conduction bliss to my ears) to serve as the walls of an ideally airtight conduit. The pads are a crucial, deeply influencing element to the sound of every Grado headphone.
Also, you're so right about how scary it is to try prying open such a thick spring steel headband on such a rare, expensive and old headphone!
