The mid-range of the Aquarius is definitely better than the Hugo2. Much more focus and clearly defined vocal. The Chord Hugo2 is a little bit more blurry in comparison.
This is a major factor IMO. 80-90% of the music is in the midrange, life and soul of the music. I’d easily choose the Aquarius for this reason alone. I do however recognize that each listener has their individual priorities. Congratulations on acquiring your new DAC. Seems to be a winner.
