I've been burning it in over the past month and it continues to get better. While I haven't tried every $8k DAC out there, I'm not afraid to say that it definitely competes with DACs like TT2/mscaler stack and Wavedream based on my system. Obviously when you get to this level, you start honing in on what your preferences are and not necessarily which one is better technically since they all perform technically very well.
If anyone is curious, I'd recommend grabbing a MK1 to see if you enjoy the latest firmware and use your imagination on how good MK2 would be. It's pretty much impossible to recommend anyone a $8k DAC blindly.
