The Stream Box S2 Ultra is an optimized audio network bridge and USB signal detox device designed to meet the demands of modern listening and bring streaming capabilities even to more traditional systems.
It functions as a universal device capable of connecting any DAC with a USB input to a network, upgrading high-end converters with advanced streaming features that are future-proof without compromising sound quality.
It was created to provide a practical solution for those who own excellent audio equipment but lack network connectivity, avoiding the need for Bluetooth connections, mobile devices with analog outputs, or the forced replacement of still-performing devices.
Thanks to its network inputs and the USB A output specifically optimized for audio, powered by dedicated circuits and audiophile-grade components, the Stream Box S2 Ultra transfers data directly to the DAC, bypassing any file compatibility limits and ensuring bit-perfect transmission.
The USB detox function also allows connecting a computer via the micro USB input to send a cleaned-up signal to the DAC, free from typical PC-related interference.
Control is fully possible via dedicated iOS and Android apps based on open-source projects with extensive community support, as well as via web browser or an external monitor connected to the HDMI output, which displays the graphical interface for immediate management.
The Stream Box S2 Ultra supports major streaming services such as Spotify, TIDAL, Qobuz, and HighResAudio, provides access to a vast catalog of internet radio stations via TuneIn, and includes DLNA and Shairport functionality for direct streaming from Apple devices.
The two USB A inputs, one front and one rear, allow the connection of external storage drives for playback of personal libraries with support up to PCM 32-bit / 352.8 kHz and DSD256, as well as the possibility of ripping CDs via an external USB drive.
Full compatibility with Roon, with Roon Ready certification, and with Audirvana allows seamless integration into advanced music management systems, including multi-room setups.
Ethernet and WiFi connectivity, the use of dedicated power supplies, and the extensive feature set make the Stream Box S2 Ultra an extremely versatile and long-lasting component, capable of transforming any modern DAC into a high-level network source and, in combination with electronics such as the Pre Box S2 Digital, one of the most complete solutions in its price range.
