  • assembled w/ top audiophile-grade components, dedicated internal power supply

"Stream Box S2 Ultra closes the gap, it offers modern connectivity with its network inputs and USB A output. This USB output is perfectionized for audio signals, it uses a dedicated internal power supply and only top audiophile grade components. You won‘t run into file-support issues, as Stream Box S2 Ultra acts as a network bridge, bypassing the files directly to your digital to analogue converter. Since most DACs only have one USB input, we have designed Stream Box S2 Ultra also to be a USB detox device. Simply connect your PC to the micro USB input of the unit and connect our DAC to the audio output. This way you can clean the noisy signal of your PC, while enjoying your music with it. Our new remote control iOS and Android App is based on an opensource project and has a large community behind it. This guarantees full support and future improvements." - Pro-Ject
