I found out something about getting the most out of this wonderful unit. In the settings section, I reviewed the setting and made sure everything was turned off that was not needed including the dither setting to off. When I got to HP gain out setting it was on high, not that I use headphones but I just wanted to set it to low, when I changed it from high, medium, and too low, the sound changed and I'm using the XLR outs to my Luxman C800-F preamp. The sound when from very good to oh my god, everything improved from the highs to the lowest of lows, there was more body and warmth, deep bass, and airly and extended highs. I repeated this several times and every time depending on which setting it affected the sound output. So if you own this unit or the lower model the Ruby, you might want to check this out for yourself, because the change in the HP gain section is impacting the final sound you hear from the unit.
