Simply amazing!
The DO200 is a linear Dac with an overall signature of being crystal clear and dead silent with the noise floor.
The midrange of DO200 is clean, detailed, vivid, and very wide.
The bass feels sharp and deep, dense, but not overbearing in amount.
The treble is clean, airy and brightly open, with good extension up to the highest treble notes. 
The soundstage is not just wide, but also deep.
Overall an awesome Dac from SMSL
