Same here. I demoed the hd800 shorty after release and wasn't impressed. I have continued to see reviewer after reviewer mention then as one of the best dynamic headphone over the last seven years and when the HD800s came out I decided to pick up a second pair of original HD800 to try for an extended period.
I am a convert. With my Mojo (and also my home tube setup) the HD800 are my reference headphone. I am listening to my music collection again with 'new ears'
The moment I listened to my old music collection, I fell in love with it once again. Though that means my Stax purchase was kinda a waste of money... I was going to return to estats but too much hassle.
Speaking of Mojo, I've tried the Mojo with HD800 and while it sounded nice, it seemed to push the Mojo almost to its limit since the owner said "Wow it lights blue" which might mean almost full volume.
Considering that, I wonder how about Hugo. Is there anyone here who pairs their HD800 with Hugo? It looks convenient so I'm a bit interested.
