    I remember Jason mentioning that the chip has greater then 16bit THD despite only being 16 bits. I saw it on the spec sheet once but I don't see it anymore.

    From Mike's previous comments here and elsewhere, it seems there are at least two ways the Schiit crew squeeze extra resolution out of their DACs. The first is a byproduct of balanced implementations. On the Yggy for example, two 20-bit DACs (one per phase) double the resolution for a balanced signal, resulting in 21 effective bits. Here is [a relevant post on HF]. This obviously doesn't apply to Mimby since it isn't balanced. The other way, which I think is a relatively recently development for Schiit, is dither. Here is [a post] where Mike confirms that the blacker background of Yggy v2 is partially attributable to dither. In [this post], Marv indicates that the Mimby v2 firmware also seems to add dither. Schiit may have other tricks up their sleeves, but these are the ones they have mentioned publicly.

    What an interesting comment from Mike regarding blackground and dither.
