This is a review and detailed measurements of the SMSL DO200 MKII stereo USB DAC.

Not much to complain about here as it fits the latest design of SMSL line. I like the clarity of the LCD and large volume indicator. Back panel is a you expect:

Standard SMSL remote control is provided.

SMSL DO200 MKII Measurements
Let’s start with our usual dashboard with XLR output:

Superbly low noise and distortion lands the unit in our 20 best DACs tested as far as sum of distortion and noise:

RCA output is nearly as good:

Performance is noise limited as is the case with all DACs in this tier:

What noise there is, is very low:

And well below threshold of audibility (assuming 120 dBSPL playback).

Linearity is perfect:

Jitter is almost as perfect:

IMD distortion is well under control:

Multitone tone test shows extremely low intermodulation distortion:

Unlike some other DACs, there are only three filters to choose from:

As noted I would go with the default Fast Linear.

I was a bit surprised to see higher than expected noise level in our wideband test:

Quick look at the spectrum shows that it is due to noise shaping:

Actual harmonic distortion is under -130 dB which is superb. So not a concern.

Conclusions
Another superb offering from SMSL in the “mid-price” category of DACs. Don’t know what else needs to be said!

I am happy to recommend the SMSL DO200 MKII.
