Pro-Ject Stream Box S2 Ultra Black - NEW OLD STOCK


An EISA award winner, the Stream Box S2 Ultra is a multi-room enabled, audio optimised network bridge and USB detox device with new control app for added convenience.

Pro-Ject Stream Box S2 Ultra offers modern connectivity with its network inputs and USB A output. This USB output is perfected for audio signals, it uses a dedicated internal power supply and only top audiophile grade components.

Network Ability

With the gaining ground of internet streaming services such as TIDAL or Spotify, the consumer's interest has shifted towards network-enabled devices. Many great sounding products though do not offer any network ability, either because they are too old or their main focus is not on this. The solution has often been to replace them with a new and modern device, stream audio via Bluetooth or to compromise and use a smartphone or tablet via the analogue output to feed active speakers or amplifiers.

Smart addition

You won‘t run into file-support issues, as it acts as a network bridge, bypassing the files directly to your digital to analogue converter. Since most DACs only have one USB input, Stream Box S2 Ultra is designed to also be a USB detox device. Simply connect your PC to the micro USB input of the unit and connect the DAC to the audio output. This way you can clean the noisy signal of your PC while enjoying your music.

Remote Control

The new remote control iOS/Android App is based on an opensource project and has a large community behind it. This guarantees full support and future improvements. Stream Box S2 Ultra is fully remote controllable via smart devices and a regular web-browser. It offers support for the most popular streaming services: Spotify and TIDAL.

Both services offer you a sheer endless amount of music, guaranteeing you, that you never run out of music to listen to. By implementing Shoutcast, we also give you the option to listen to various internet radio stations. You can listen to your favourite radio shows, the news and discover new channels from all around the world – with just a few clicks.


The back-sided HDMI video output lets you connect your monitor to the Stream Box S2 Ultra. It will then show you the graphic user interface, ready to act on your commands. With the implementation of Shairport, we were even able to give the iDevice users out there another possibility to send data to our Stream Box S2 Ultra.

There are two USB inputs on Stream Box S2 Ultra, one front sided and one back sided. Both give you the possibility to connect an external hard drive to the unit. Via one of the various control scenarios (App, Webbrowser, external monitor) you can pick from your own selection of audio. The file system support goes up to PCM 32bit / 352.8 kHz and DSD256.

Roon Ready

Pro-Ject are big supporters of the Roon software, so it comes as no surprise that the Stream Box S2 Ultra is Roon Ready. This means you can simply pick your unit in the Roon interface and send bit-perfect audio streams to it over your network. This incredible feature set makes Stream Box S2 Ultra bullet-proof for all future events. Together with Pre Box S2 Digital, they become the most versatile and audiophile set in its price class.
