Fosi Audio S3 Balanced HiFi Streamer/DAC/Preamp

 

The Fosi Audio S3 is meticulously engineered for those who demand high fidelity and versatility from their streamers.

Its balanced circuit design with XLR outputs minimizes crosstalk and maintains signal integrity, aided by ultra-low-noise LDOs, Japan-made ELNA capacitors, and a fully isolated power module that separates analog and digital circuits for a purer listening experience.

 

With support for an extensive range of streaming protocols including Google Cast, Apple AirPlay 2, DLNA, Roon Ready (under certification), Spotify Connect, and TIDAL Connect, the S3 makes it easy to access your favorite music from virtually any source. The device’s dual-band Wi-Fi (2.4G/5GHz) with Wi-Fi 6, robust Ethernet port, and advanced Bluetooth 5.3 (supporting SBC and AAC codecs) guarantee rock-solid, low-latency wireless and wired connections for seamless multi-room playback. The S3 integrates perfectly with AirPlay 2 speakers, Amazon Echo, and Google Home, making it ideal for whole-home synchronized audio.

 

Functionality is at the heart of the Fosi Audio S3, which serves as an all-in-one solution for modern hi-fi systems. It can act as a pure digital transport, a high-resolution DAC, a preamplifier with adjustable volume and EQ (via the Fosi Audio app), or as a home theater hub with its HDMI eARC input and dedicated subwoofer output.
