Stream Box S2 Ultra offers modern connectivity with its network inputs and USB A output. This USB output is optimized specifically for audio signals. The streaming device uses a dedicated internal power supply and audiophile-grade components to achieve the sonics that has made this unit famous. You won’t encounter file-support issues as Stream Box S2 Ultra acts as a bit-perfect network bridge, sending files directly to your digital-to-analog converter via USB.
 
Since most DACs have one USB port, we have designed Stream Box S2 Ultra also as a USB detox device for a cleaner audio signal. Simply connect your PC to the micro USB input of the unit and connect your DAC to the audio output; this way the digital signal is optimized while you listen. Control is simple thanks to our iOS and Android-compatible “Pro-Ject Play” app. Alternately, the StreamBox S2 Ultra can be controlled via web browser or the very popular Roon software.
