Terrible pics, but you get the idea:
I've only had limited time to mess with it, but so far so good. Fed it from the Toslink out of my Resonessence Labs Invicta Mirus which may be a bit overkill.... but it's what I had ready to go at that moment.
This far I've tried it with LCD-2, HD800, Noble 4C, and Westone ES5 - a good mix of dynamic, planar, and armature based designs. I love the inky background, no hiss with CIEMs, yet plenty of drive for the bigger cans.
Looking forward to your review.
