I suspect it will be worse with almost any DAC. I quite like the Mojo with an AK100/120 but the QP1r is clearly better line out then when adding the Mojo tos out. The internal dac/line circuit seems very well done and you don't have to deal with the clock recovery and jitter involved with SPdf. If they're close in performance the inboard DAC is at an advantage and in this case seems to be show it.
