ProJect Stream Box S2 Ultra

A Streamer For The Modern Era: Add high-resolution streaming to your traditional hi-fi instantly with the Stream Box S2 Ultra. Simply plug into your USB DAC (or amplifier, or pre-amplifier) and listen to music using Spotify, Tidal, Roon, AirPlay, DLNA and local network drives within minutes!

Roon Ready And Raring Go: The Stream Box S2 Ultra uses Roon's own RAAT technology, so you can connect it to a traditional USB DAC (or amplifier, or pre-amplifier) to create a Roon Ready endpoint, and bring even more gear into your whole-home audio system.

Stream Just About Anything Your Heart Desires: Got a mighty digital library at home? The Stream Box S2 Ultra can also handle music from USB hard drives, NAS drives and your PC's library; connect to the Micro-USB In, and it'll even clean up USB noise from your PC in the process, giving your collection an extra clarity you never knew you could have. No need to worry about file compatibility, either — the Stream Box S2 Ultra supports almost any file type that your DAC does, even very high-resolution file types like 352.8kHz PCM and DSD256. If your DAC is MQA-enabled, the Stream Box S2 Ultra can pass-through MQA signals without alteration, for exact unfolding by your DAC.

Under The Hood: In developing the Stream Box S2 Ultra, its designer John Westlake (also the mastermind behind Pro-Ject’s Pre Box S2 Digital) decided that it must do three critical things; Provide bit-perfect HiRes (no data manipulation), support DSD files and allow the DAC to be Audio Clock master. The Stream Box does these things easily with its quad core Raspberry Pi 3 and Volumio software.

The Raspberry Pi 3 is an effective bit of hardware, but it was designed to be cheap rather than for sound quality. Those design choices mean there’s far more noise, especially from the power supply, than would be suitable in a high-resolution streamer. Yet Pro-Ject have it all under control. The high-calibre design of the Stream Box S2 Ultra removed jitter, RF and ground noise through a host of clock improvements, low-noise power supplies, and the capacity for the 5V USB power output to be disabled where not required.

About Pro-Ject

Pro-Ject Audio Systems was founded in 1991 by Heinz Lichtenegger. The products are designed in Mistelbach, Austria and exclusively made in Europe at manufacturing plants in the Czech Republic and Slovakia and then shipped to more than 80 countries world-wide. Pro-Ject are best known for their high quality belt drive turntables which are often seen as the best in class at their various price points. In particular the Debut series of turntables has been the go-to record player of choice for many a budding music lover at the affordable end of the price spectrum.

Pro-Ject turntables allow you to experience again the clarity, warmth and magic to be found in the grooves on your vinyl, at very reasonable prices. With simple designs and high construction standards, performance has always been the priority. Fully manual operation coupled with the best materials and components available at each price level ensures the best possible value. Of course, here at Audio Trends, we've been selling them since the beginning of time (almost) and due to our passion for all things analogue - read vinyl - can tell you everything you need to know about our fantastic range of their products.

Whilst turntables are a large part of the Pro-Ject story the company has also ventured into high quality micro sized audio products in recent years including phono preamps, DAC’s, streamers and amplifiers.

ProJect Stream Box S2 Ultra Review

“Is there anything it can’t do? In every combination I tried, the S2 Ultra’ pass-through USB ‘cleaner’ revealed more detail in the sound, and greater weight and definition in the bass.” Andrew Everard & Paul Miller, Hi-Fi News
