Audiophonics ES9018K2M DAC is good sounding (natural round and soft sound with good bass, mid, and high distinction), but not finalized product for advanced DIY enthusiasts, ideally understanding French… 
You need to know what you are signing up to when buying it.
Thus, in my view for general customer the Allo Kali Reclocker with basic Piano DAC (attention not the 2.1 version) is better choice (if you don’t mind a little more harsh sound, which again on some tracks gives very pleasant sparkling transparency feeling comparing to more subtle Audiophonics).
