Holo DAC KTE here and I haven’t a clue and I think this might be a good thing. I have noted huge difference in presentation based upon the quality of the recording and have handicapped my DAC in that I use the coax out, but I did A/B a very good coax to a pretty good USB and decided to stay with the coax. I can hear the difference between the same piece with CD quality vs higher Qobuz streamed. I think I’ve either enjoyed what I listened to and will listen again in the future, or ask myself, what the hell were they thinking when they recorded this mess. The main surprise with regards to my DAC is how good it sounds when the Aurender passes the information by coax. I really didn’t expect this.
