Product Details

Today‘s market is getting overcrowded with lots of wireless streamers. Most of them are only focused on a good App, but the real sound quality is determined by the quality of the DAC and the analogue audio output stage. Also, from an esthetical viewpoint, many of the streamers are just plastic boxes and no amp or other components are in it. In recent times Pro-Ject has been producing the some of the best micro high-end amps on the market, like the Maia S2 or the Stereo Box S2.

For these products Pro-Ject developed a fitting streamer, which matches the sound quality and aesthetics of these amplifiers. It is very easy to use per App and has all features of modern-day streamers, including proper multiroom functionality. It offers support for high resolution data up to 24bit / 192kHz, as well as the possibility to connect to multiple Stream Box S2 Multi to form a multiroom setup.

The multiroom stream quality remains on CD quality (16 Bit/ 44.1 kHz) which, for multiroom applications, is an enormous amount of data and great audio quality. The possible zones are limited to 10 or 6 zones (Ethernet or WiFi) to ensure a flawless transmission considering the high data rates. Usually multiroom devices which offer a high number of zones are data reduced to max. MP3 quality to ensure a flawless stream. Moreover, two units can also be connected to build a stereo pair (with assigned left and right channel).
