SMSL DO200 Pro balanced DAC with twelve xCS43131 processors. Outputs 5.2 volts and hits a 125 SINAD score which is state of the art. We bought this to do a review so it's tested completely and was a joy to get to try out. Best paired with an amplifier that can handle a 5 volt input DAC without clipping in high gain (like the Topping A90D Discrete, A70Pro, SMSL SP400). If you have any questions about this latest flagship DAC please send a note. I'm very active in the audio community (major contributor at audiosciencereview and "Headphonus Supremus" at Head-Fi under the same handle) and like to talk shop. Warranty registered for 12 months from listing date.
