Can someone with an AK100ii talk about the details of the SQ difference of AK headphone out (balanced or SE) vs. optical out to the Mojo. I'm sure the Mojo is louder, but I am more concerned about the detail retrieval, dynamics, sound stage, musicality, low volume performance, tonal qualities, and signature differences. I love my AK100ii balanced to my Hidition NT6pros, but the pros can scale higher with a better system and I don't want to be tied to my desktop. Am I splitting hairs, or is there a significant improvement with the Mojo with CIEMs or easy to drive HPs. Or is it just a signature change with the same level of performance? Anyone?
