I never got the Yggy, but did own the Gungnir a few years ago.
It was a very good DAC, close to my Ayre Codex.
Schiit makes some good gear at great prices.
However, I made a leap of faith and bought a Brinkmann Nyquist 2. It was more than I would normally spend, but, another audiophile who I respect bought one and sang it's praises. Since we both share similar experiences with equipment, I bought it. And, I have to say it is all that it is said to be.
There are other manufacturers out there, like MSB, and in a similar price range. So, I will say that if you are serious about digital sound reproduction, please give them a listen. It seems that you really have to spend around $10K to get to this level, but if you are patient, I bet it will be coming down in the future as digital is in it's infancy.
