Fosi Audio has officially announced the S3, a new all-in-one HiFi component that combines a network streamer, DAC, and preamp into a single compact unit. Designed to simplify modern home audio setups, the S3 aims to deliver high-resolution audio playback, wireless streaming, and flexible connectivity at an accessible price point.
According to Fosi Audio CEO Ryan Huang, the S3 represents a long-awaited expansion into the streaming category, bringing together playback, decoding, and system control into a unified platform for everyday listening.
Built for Modern Streaming: Wi-Fi 6, Bluetooth 5.3, and Full Platform Support
At its core, the Fosi Audio S3 is built around a dual-band Wi-Fi 6 streaming platform, ensuring fast, stable wireless performance. For added convenience, it also includes Bluetooth 5.3, making it easy to stream music directly from smartphones and tablets.
The S3 supports a wide range of popular streaming protocols, including:
- Spotify Connect
- TIDAL Connect
- AirPlay 2
- Google Cast
- DLNA
This broad compatibility allows users to stream directly from their favorite apps or access music libraries stored on local NAS drives, making the S3 a versatile hub for both cloud-based and local audio playback.
High-Resolution Audio with AKM DAC Architecture
Beyond streaming, the S3 functions as a complete digital front-end, capable of operating as a standalone streamer, DAC, digital transport, or preamp depending on system needs.
It supports high-resolution audio up to 32-bit/384kHz, ensuring detailed playback for lossless and high-res music formats. Internally, the S3 is powered by:
- Amlogic A113X streaming platform
- AK4493SEQ DAC chipset

This combination is engineered to provide a clean, low-noise signal path, delivering transparency and accuracy that align with audiophile expectations at this price tier.

This flexibility allows the S3 to function as the centerpiece of a 2.1 system, a HiFi stereo setup, or even as part of a broader AV configuration.
Additionally, multi-room playback is supported via AirPlay 2 and Google Cast, enabling synchronized audio across multiple devices throughout the home.
