The audio engineer here let me take them home last night.  
 
Hated them. 
 
I ran them through my RKV and used my NAD 541.  
 
Bloated, no detail, crappy closed headphone.  Put on my Senn 600s... night and day.  
 
A lot of guys here think they're pretty good.  I'm threatening them with bringing in my gear so they can get a different opinion.  
 
The Ultras would probably benefit with a better amp... but they still were bassy.
