The Fosi Audio S3 is the company’s first foray into high-resolution streaming. It’s a network streamer, a high-resolution DAC and a preamp, designed to bring your home’s traditional hi-fi system up to today’s modern streaming standards. It supports a wide range of streaming protocols, including Spotify Connect, TIDAL Connect, AirPlay 2, Google Cast, and DLNA. More than a streamer, the S3 can function as a standalone digital transport, DAC or preamp, allowing it to work in a wide range of home stereo and home theater systems. According to the brand, it can “serve as the centerpiece of a 2.1 system or a traditional hi-fi setup.”
