This device (SMSL M200) should have been on the market for some time? From the price and model system of SMSL, this is an inexpensive device (279USD?). Considering the discussion in the forum, I applied for a sample for measurement.
In terms of design and workmanship, there is really nothing to say-normal level.
AKM4497, balanced output...
The question now is... Measurement results
Although the value of SINAD is good here, we can see some other problems-it seems that due to the "low cost" of digital circuits, we can find some side lobes in the FFT. This high probability indicates that the device's own jitter performance is not good (I measured the COAX and Opt inputs, and the problem still exists)
