But if you want to use the unbalanced Mimby, you probably can't take advantage of the Jot's balanced output. I was trying to decide between the Jotunheim and Valhalla 2 for an amp upgrade and asked Schiit if I could get the benefit of the increased power of the Jotunheim's balanced outputs if I continued to use Mimby as my DAC. Their response: "If you go with Mimby as your DAC, you won't get a truly balanced configuration." (I did ask Schiit to clarify whether or not I would be able to use the more powerful balanced outputs of the Jotunheim even if, as I already knew, the setup was not truly balanced, but surprisingly got no response.) I bought the Vahalla 2, which should be delivered tomorrow.
BTW, if you really want to go balanced, you might want to consider the Cavalli Liquid Carbon X, which is available now on Massdrop. It has a very different topology than the Jotunheim, using phase splitters on its single ended inputs to create a balanced signal through the amp. According to Cavalli and Massdrop, you can connect an unbalanced DAC to the RCA inputs and still get a balanced output. I seriously considered this, but aside from leaning to tubes for my HD700 and incoming 6XX, the LCX is not estimated to ship until February 28, 2018, in the end a deal breaker.
