Product Summary
The Pro-Ject Stream Box S2 Ultra is a high-resolution network streamer designed for customers who want to add serious streaming capability to an existing DAC or hi-fi system without replacing the components they already love. Rather than acting as a conventional all-in-one streamer with its own internal DAC, it is built as a dedicated digital transport, helping you get more from a quality external DAC via its audio-optimised USB output.
That makes it especially appealing for customers who already own a good DAC but want a cleaner, more flexible and more purpose-built source for streaming music. Support for services including TIDAL, Spotify and Qobuz, along with internet radio, DLNA, Roon Ready certification and local USB storage playback, gives the Stream Box S2 Ultra the versatility to sit at the centre of a modern digital music system while keeping operation simple through app, web browser or Roon control.
It is also designed with sound quality firmly in mind. Pro-Ject uses dedicated internal power supplies and an audio-optimised USB output to help deliver a cleaner digital signal to your DAC, while the PC-Detox micro USB input gives you another way to reduce noise when using a computer as a source. For customers wanting a compact, highly capable streamer that can unlock more from an external DAC, the Stream Box S2 Ultra is an excellent solution.
