Eagerly awaiting when these beasts are finally released I'm pretty set on my alpha dogs as my endgame headphones and I'm already finding them to be pretty damn good off my Lyr, so I'm looking forward to possibly finding my endgame DAC/amp combo in the rag/ygg. The ability to drive speakers is a nice plus for the far off day I decide to "grow up" from headfi and dive down the other transducer rabbit hole.
I just got mine and they are black : ] ADs are endgame closed headphones IMO and I've heard the LCD-XC. I am in awe by the tightness of the bass that doesn't bleed into the mids or the highs. They approach the LCD-2 in terms of bass quality and quantity but slightly more polite and balanced.
