Seller's Description

Project Stream Box S2 Ultra streamer plus Pre-Box S2 Digital pre plus Inakustik USB

Stream Box S2 Ultra: the smart addition

Stream Box S2 offers modern connectivity with its network inputs and USB A output. This USB output is perfectionized for audio signals, it uses a dedicated internal power supply and only top audiophile grade components. You won‘t run into file-support issues, as Stream Box S2 Ultra acts as a network bridge, bypassing the files directly to your digital to analogue converter. Since most DACs only have one USB input, we have designed Stream Box S2 Ultra also to be a USB detox device. Simply connect your PC to the micro USB input of the unit and connect our DAC to the audio output. This way you can clean the noisy signal of your PC, while enjoying your music with it.

Our new remote control iOS and 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: feature galore!

Stream Box S2 Ultra is fully remoteable via smart devices and a regular web-browser. It offers support for the most popular streaming services: Spotify, TIDAL, Qobuz, HRA Streaming. These services offer you a sheer endless amount of music, guaranteeing you, that you never run out of music to listen to. By implementing TuneIn, 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 possibilty 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 harddrive 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.

Here at Pro-Ject, we are big supporters of the Roon software, that is why we wanted the Stream Box S2 Ultra to be Roon Ready and fully certified. This way you can simply pick your Stream Box S2 Ultra 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.

About Pro-Ject

Pro-Ject Audio Systems traces its roots to 1991 in Austria's Weinviertel region, north of Vienna, where founder Heinz Lichtenegger launched the brand amid the CD revolution. Kicked out of music school as a youth, Lichtenegger channeled his passion for analog sound into affordable, high-quality turntables at a time when vinyl seemed obsolete. His debut Pro-Ject 1, hand-assembled in the Czech Republic, earned rave reviews as a top high-end device, igniting a success story that relocated headquarters to Vienna before returning to Mistelbach in Lower Austria.

The brand excels in turntables, establishing itself as the world's largest and leading producer in that category, while expanding into a full spectrum of hi-fi components since 2000. Offerings include amplifiers, DACs, headphone amps, speakers, cables, and phono stages, all emphasizing essential sound reproduction with durable materials and minimalist design. Manufacturing remains European—primarily in Czechia, Slovakia, and Germany—prioritizing sustainability through local sourcing, short transport, and products built for longevity.

Pro-Ject holds a commanding niche as the go-to for mid-tier audiophiles seeking boutique European craftsmanship without extravagant pricing. Distributed in over 80 countries, it appeals to vinyl revivalists and discerning buyers who value analog purity, innovation, and value-driven performance over flashy excess, cementing its reputation as a pioneer in accessible high-fidelity.
