Stream Box S2 Ultra won EISA’s 2018-2019 “Best Product” of the year as a streamer, but streaming is not the only thing it excels at. Powered by the popular open-source Raspberry Pi platform, it features never before seen control scenarios and unprecedented audio performance. With USB, HDMI, Ethernet, Bluetooth, Airplay, Roon and so much more, adding the Stream Box S2 Ultra is a smart addition to your home audio setup your guests will appreciate.

The ways you can connect the devices you already own to control your music with Stream Box S2 Ultra are endless... Borrow a friend's USB stick and jam out in the living room, or Bluetooth your Spotify playlist directly to the unit from your phone. Plug in a mouse and connect a keyboard to either of the two USB inputs and your little control hub is always ready — at your command. Power users will have the most fun using the HDMI port with a touch screen with hands-on control for the most tactile user experience.

Adding this to your wireless network will open many possibilities for you to stream high-resolution audio with bit-perfect quality to your favorite DAC. 

With multi-room support for up to six devices, whether it’s with Roon, a DLNA compatible networked NAS, storing your entire music collection, a friend’s USB thumb drive plugged into the front panel, or your favorite streaming service, Stream Box S2 Ultra integrates all of it. The Volumio software can see Tidal, Qobuz, Spotify, or web radio playing directly from the Stream Box Ultra. When you select either Bluetooth or iOS input in the Stream Box Ultra’s software, you can Bluetooth directly to the unit from your Android phone or any Apple iOS device using Airplay.

Pro-Ject Stream Box S2 Ultra can pass MQA to your DAC with bit-perfect audio and it’s Roon Ready — plus the USB Clarifier mode will “clean” the noisy digital audio output coming from computers.

We’ve never seen so much packed inside something so small for this price.
