Fosi Audio S3 Balanced Hi-Fi Streamer/DAC/Preamp

Upgrade your home audio setup with reference-grade sound and wireless streaming with the S3 Balanced Hi-Fi Streamer/DAC/Preamp from Fosi Audio.

The S3 has inputs to accept a TV, AVR, CD player, turntable (with phono preamp), and more.

Output that audio to a power amp, decoder, or active speakers. Isolated analog and digital architecture, a balanced circuit, and an independent AK44935EQ DAC come together to deliver reference-grade sound up to 32-bit PCM 384 kHz quality. The S3 also adds the ability to stream from online services, such as TIDAL Connect and Spotify Connect, as well as your home NAS via Wi-Fi 6 (802.11ax). Mobile devices and laptops can also send music through the S3 via Bluetooth.

Premium Components for Accurate Sound

Integrated into the S3 is an independent AK4493SEQ DAC that can produce audio with a low THD+N at 0.00018% and a high SNR up to 120 dB. This reference-grade sound supports PCM output up to 384 kHz/32-bit. Add in an ultralow noise LDO power supply, dual op-amp differential amplification, and balanced XLR outputs, and you also get impressive clarity with detailed separation and a wide soundstage.
