Pro-Ject Stream Box S2 Ultra Media Streamer

Universal Bridge Puts Any USB-Equipped DAC into Your Network, Serves as High-Resolution Streamer: Roon-Ready Pro-Ject Audio Stream Box S2 Offers Unprecedented Control, Flexibility, and Value

A universal device that puts any USB-equipped DAC into your network and serves it as a no-compromise streamer, the Roon-ready Pro-Ject Audio Stream Box S2 Ultra network bridge/streamer is the first audio component of its kind. Many audiophile-grade DACs either do not offer network ability or cost a handsome price for the capacity to do so.

The alternative for listeners wanting to stream was to either purchase a brand-new DAC, stream via Bluetooth, or, further compromise by using a smartphone or tablet via an analog output to feed active speakers or amplifiers. Winner of the 2018-2019 EISA Award for Best Product (Streamer), and providing both wired and wireless connection options, Stream Box S2 Ultra changes everything.

Offering built-in support for popular services such as TIDAL, Qobuz, and Spotify, the multi-room-enabled Stream Box S2 Ultra arrives with an optimized USB-A output that uses its own dedicated internal power supply and top-grade parts. And since Stream Box S2 Ultra serves as a bridge, bypassing all files directly to your existing DAC, you'll have no problems with file-support issues. Pro-Ject also engineered it as a "USB detox device" that, when you connect your computer to the micro USB input and your DAC to the audio output, the noisy signal from your PC or Mac gets cleaned.

The control choice offered by Stream Box S2 Ultra are equally cool. Use your smart device, a computer, or Pro-Ject's new remote-control app to quarterback the commands. In addition to services such as TIDAL, Stream Box S2 Ultra touts Shoutcast, which gives you the chance to listen to Internet radio with just a few clicks. And there's still more. A rear-panel HDMI video output lets you connect a TV and brings up a graphic user interface. Shairpoint provides iDevice owners yet another option to send data to Stream Box S2 Ultra. Last but not least, the presence of two USB inputs invite you to hook up an external hard drive – and enjoy sound in up to DSD256 or 32-bit/352.8kHz.

"Ah-ha – here was a product that appeared to offer what I was looking for in an affordable server and network bridge... Strongly recommended to those who don't want to drop big bucks on a networked digital music system."
– John Atkinson, Stereophile

"What this Pro-Ject does so well is what so many of the company's Box Design devices achieve: it provides a simple, logical solution to a problem, performs impeccably, and does so in a form so small it could even be hidden away if preferred."
– Andrew Everard, HiFiCritic, Best Buy rating
