PRO-JECT EMBRACES NEXT-GEN MUSIC STREAMING
Pro-Ject may have built a foundation based on its high-performance turntables but with a complete range of Hi-Fi electronics, its latest release, the Stream Box S2 Ultra, proves that it's a cutting-edge company in the world of modern Hi-Fi.
The Stream Box S2 Ultra is "a versatile, audiophile-grade network bridge" that is built upon the revolutionary small-form-factor quad-core industrial version of the Raspberry Pi.
It brings a simple method of adding high-resolution music streaming to any traditional hi-fi system via a USB connection to a DAC. It supports Spotify, TIDAL, Roon, AirPlay, DLNA and of course music stored on your local network.
The key feature for enthusiasts will be its Roon Ready certification, delivering a simple way to add another audio end-point to your multi-room ecosystem.
Inputs include 2 x USB-A, Micro USB-B, and both wired and wireless network. Outputs are limited to just USB-A for connection to a DAC, and a video-only HDMI.
The Stream Box S2 Ultra will handle just about any file type that your DAC is compatible with, including 352.8kHz PCM and DSD256. It will also pass-through MQA files for exact unfolding by an MQA capable DAC.
Designer John Westlake placed emphasis on three critical areas - provide bit-perfect Hi-Res with no data manipulation, support for DSD, and allow the DAC to be the master audio clock.
The result was to build upon the Raspberry Pi in conjunction with open-source software Volumio. Westlake's wave of the magic wand over the Raspberry Pi led to improvements relating to decreasing power supply noise and RF, as well as eliminating jitter.
Westlake said:
This industrial version of the RPi3 called the CM3 module allows us to optimise the streamer hardware (PSU, RF and Clocking) while maintaining software compatibility with RPI. An important goal of our streamer solution is that we wanted an optimised “audio” streaming solution while not limiting the customer to a single software solution – for those skilled in software they can install any of the RPI based media players (Moode, LMS and even Kodi) etc.
Westlake expanded upon why he elected to use the Raspberry Pi, along with delving into more details on the improvements that have been made in a post you can read here.
The Pro-Ject Stream Box S2 Ultra has been extensively developed and refined to bring a simple, yet high-quality way of adding high-resolution streaming to your Hi-Fi system.
Available now, the Pro-Ject Stream Box S2 Ultra sells for $1,199 RRP and is available in black or silver.

applause awards
Each time StereoNET reviews a product, it is considered for an Applause Award. Winning one marks it out as a design of great quality and distinction – a special product in its class, on the grounds of either performance, value for money, or usually both.
Applause Awards are personally issued by StereoNET’s global Editor-in-Chief, David Price – who has over three decades of experience reviewing hi-fi products at the highest level – after consulting with our senior editorial team. They are not automatically given with all reviews, nor can manufacturers purchase them.
The StereoNET editorial team includes some of the world’s most experienced and respected hi-fi journalists with a vast wealth of knowledge. Some have edited popular English language hi-fi magazines, and others have been senior contributors to famous audio journals stretching back to the late 1970s. And we also employ professional IT and home theatre specialists who work at the cutting edge of today’s technology.
We believe that no other online hi-fi and home cinema resource offers such expert knowledge, so when StereoNET gives an Applause Award, it is a trustworthy hallmark of quality. Receiving such an award is the prerequisite to becoming eligible for our annual Product of the Year awards, awarded only to the finest designs in their respective categories. Buyers of hi-fi, home cinema, and headphones can be sure that a StereoNET Applause Award winner is worthy of your most serious attention.
