Fosi Audio S3 Music Streamer

Our Take

The Fosi Audio S3 is an exciting addition to Fosi's lineup, bringing modern music streaming, a quality DAC and preamplifier functionality together in one compact unit.

What makes the S3 particularly interesting is how much it offers for the money. With Spotify Connect, TIDAL Connect, AirPlay 2 and Google Cast, you can stream your favourite music directly without needing a separate streaming device.

We especially appreciate the inclusion of balanced XLR outputs, an AKM DAC and HDMI eARC, making it equally practical for a dedicated HiFi system or a living room setup.

Pair it with the Fosi Audio ZA3 or V3 Mono amplifiers, and you've got yourself a capable, affordable streaming HiFi system without the usual complexity.

Product Details

The Fosi Audio S3 is an all-in-one HiFi music streamer, DAC and preamplifier designed to make high-quality music streaming simple and accessible. Instead of relying on multiple devices, the S3 allows you to enjoy your favourite music streaming services through your existing HiFi system, all from one compact unit.

With built-in WiFi 6 and Bluetooth 5.3, the S3 makes wireless listening effortless. It supports popular streaming platforms and technologies including Spotify Connect, TIDAL Connect, AirPlay 2 and Google Cast, allowing you to play music directly from your smartphone or tablet. You can also use the Fosi Audio app to control playback, adjust sound settings and manage your listening experience.

At the heart of the S3 is the AKM AK4493SEQ DAC chip, responsible for converting digital music into clean, detailed analogue audio. Its fully balanced audio design and XLR outputs make it a great match for compatible HiFi amplifiers, while conventional RCA outputs offer flexibility with other audio systems.

The S3 isn't limited to music streaming either. With HDMI eARC connectivity, you can connect your TV and enjoy movies, shows and everyday television through your HiFi speakers. A dedicated subwoofer output also makes it easy to add extra bass to your system.

For added convenience, the S3 comes with a remote control, adjustable equaliser settings and 12V trigger connectivity for compatible amplifiers. Its compact design makes it easy to fit into a desktop setup, living room or dedicated listening space.

Whether you're upgrading an existing amplifier with modern streaming capabilities or building your first HiFi system, the Fosi Audio S3 offers a convenient and versatile way to enjoy your music without unnecessary equipment or complicated setups.
