For the price this thing is great! It's well build, looks good and functions as promised.
Menus are very clear and settings are easy to changes according your personal needs.
The remote also works better then the one from the Topping product I had before.
The display is clear and informative. (brightness is high, so you can set it to the lowest level and it is still readable from a good distance)
But better still: objectively it lives up to the specs the manufacturer shows on the product page. (https://www.audiosciencereview.com/forum/index.php?threads/smsl-raw-mda-1-dac-headphone-amp-review.56430/) It does not sound. It just transforms from the digital domain to the analog and amplifies (actually it attenuates) the signal without any audible artifacts.
