Not exactly equivalent dacs, but I can tell you the Mojo has a very smooth presentation, maybe a bit rolled off in the treble, but It seems to really clean up less than optimal recordings, very solid bass.
Schiit, more of an exciting, dynamic sound, kicks harder.
If you going to connect by USB, I would go for the Gugnir, not a fan of mini USB on the Mojo.
Better than either to me is a Roksan K3, there might be some still around at £400, it is however a much bigger unit, but build quality is on another level.
