The Pro-Ject Stream Box RS is an audio streaming device that allows users to play high-resolution audio files through their audio systems. The device follows the Box Design sub-brand of Pro-Ject, which is recognized for its stylish, compact form and quality audio performance. It features a minimalist design with a small chassis resembling the size of a paperback book, making it easy to integrate into various audio setups. The Stream Box RS supports a variety of file formats, including MP3, AAC/MP4, WMA, WAV, AIFF, and FLAC, and is capable of high-resolution audio playback up to 24-bit/192 kHz, thanks to its sophisticated CirrusLogic delta-sigma DAC. Connectivity options include USB ports, Ethernet, and S/PDIF digital outputs, as well as options for both wired and wireless network connections via its built-in Wi-Fi. One of the notable aspects of the Stream Box RS is that it interfaces seamlessly with various streaming services and allows users to access thousands of Internet radio stations, maintaining a focus on delivering superior audio quality for discerning listeners. However, it lacks video output capabilities, making navigation and track selection somewhat dependent on proximity to the device. Pro-Ject also hints at the development of mobile applications for better controls via smartphones. Overall, the Stream Box RS is targeted at audiophiles looking for a compact, high-end audio streaming solution that can seamlessly fit into a high-quality audio system while offering flexibility in accessing a wide range of music files.
