Extra info: The USB Box S+ from Box Design by Pro-Ject Audio uses the most advanced features and technologies in USB asynchronous data transfer thanks to a high-end XMOS chipset. This simple-to-use Digital/Analogue Converter (DAC) connects to your computer via USB and to a hi-fi system through traditional RCA leads to open the world of computer audio to your hi-fi. 

USB Box S+ up-samples data on 352.8kHz or 384kHz (44.1kHz, 88.2kHz & 176.4kHz are upsampled on 352.8kHz. 48, 96 & 192kHz are up-sampled on 384kHz), meaning every digital detail is captured for conversion – resulting in a truly musical playback through your Hi-Fi.

  • Premium 32-bit / 384kHz PCM-5102A DAC chip from Burr Brown
  • XMOS technology for lowest possible jitter
  • Upsampling to 352.8kHz or 384kHz
  • 32-bit / 384kHz asynchronous USB streaming
