Headphone options with 'Stat line transients?

Speed kills which is probably why TAS went gaga over Mr.  Speakers and Stax headphones in a recent publication.  Both of these are expensive options ($3000 +).  Is there anything that might float my boat under $2000?   I'm looking at Focal Clear or Mr. Speakers Ether Flow as candidates but I'm $keptical.  
I am rather fond of Sennheiser HD800s phones of which I own a pair I think you should put them on your list. The treble is really extended and they are super comfy also.
