I thought about putting this in the Crack forum, but I think it's true across the board. I have a Crack and I recently got a Schiit Modi Multibit and wow is it a huge improvement. The music comes alive in a way very similar to listening to vinyl. There's so much instrument separation and detail along with body. I was watching a review on Youtube of the Modi-Multibit and he described the sound as "bold" and I can see where he's coming from, it is definitely more driving more like a live concert.
So if anyone is interested in Schiit's multibit DAC's, they are worth it IMHO!
