I have owned a few Chord DACs, some good, some not so good, and I've found that the higher end units like the QB76 stood out among their contemporaries at the time of release.
That being said, they've maintained high end pricing with no significant improvement in sound. Hell, the Hugo was not significantly better than the QuteHD which, to me, was a big step back from the QB76. In the world of Yggdrasil, $10k+ DACs can no longer be "just good" but have to really excel. I'll reserve judgment until I hear it, but I suspect value proposition is low.
