Fosi Audio - S3 HiFi Music Streamer DAC Preamp - Silver

I replaced a problematic Wiim pro with this S3 and it turned out a great upgrade to my setup. It literally took about 10 min to setup with easy steps with their app and working great since then. I had to read manual to pair the remote but otherwise rest was quickly done with steps on the app. I primarily use HDMI ARC with TV, Spotify and Airplay streaming from iPhone and everything work perfectly. It's sound quality is so much better than previous streamer. It comes with remote and its super useful, I did not have it with other streamer before. I do plan to add a subwoofer in future as it has subwoofer out. BestBuy had super quick next day delivery and support if needed. I love the simplicity of use and Very Happy with my purchase.

This is my first dedicated network streamer, and I couldn't be happier. The sound is clean, natural, and surprisingly detailed, especially when using the XLR outputs. I love having multiple streaming options, whether it's Tidal Connect, AirPlay 2, or Google Cast, depending on who's controlling the music. The unit looks great on my desk, runs quietly, and has become the center of my music system. The companion app could still use some refinement, but honestly I rarely need to open it after the initial setup. If you want an affordable streamer with excellent sound quality and plenty of connectivity, this one is easy to recommend.

I got this steamer to connect my digital sources to my vintage receivers. I’ve previously had more budget streamers from another company. In comparison the S3 has much better analog output and sound. I found my old streamer would jitter sometimes, and stall out. It also had a much more veiled sound that eventually required an outboard DAC to improve to acceptable levels. The S3 has none of those issues. I have been using it with Apple Airplay to seamlessly stream apple music for many hours, daily. It sounds really good. I often forgot I was listening to streaming while enjoying some more familiar albums I normally play on vinyl or cd. I didn’t notice any issues with the sound which is great. It also uses a free app on to control streaming . It is simple and straightforward. This is definitely a great solution for a quality streamer and DAC. I also used it as a DAC for my older Denon cd player with very good results, and briefly as a streamer/preamp outputting to a Fosi V3 power amp.

Most of my listening time is dedicated to physical media either spinning vinyl or popping a CD into my player. While I love the ritual, having to constantly get up and swap discs gets tiring when I just want to sit back and dig through full discographies. I wanted a clean way to add high res streaming to my shelf without an ugly, laggy mess of adapters or long wires, and the Fosi Audio S3 fit right into my setup. Setup was fast, and it looks right at home next to my turntable, CD player, and receiver. What stood out immediately was the sound profile. With the updated companion app and its 10-band EQ, it delivers a smooth, natural, and full sound that doesn't feel too bassy or tinny, making streamed albums feel right at home alongside physical media. The convenience makes it hard to turn off. Casting via Wi-Fi from my devices is instantaneous with zero dropouts or lag. Being able to effortlessly queue up rare tracks and full albums through my main setup without leaving my desk gives me modern convenience without sacrificing the warm listening experience I care about.

I honestly bought the S3 because of its feature list, but I kept it because of how good it sounds. The AKM DAC delivers a smooth presentation that's easy to listen to for hours, and the balanced outputs pair beautifully with my integrated amplifier. One thing I really like is that Fosi focused on the features that actually matter: Wi-Fi streaming, HDMI eARC, AirPlay 2, Google Cast, and Tidal Connect. I don't miss having a screen because I control everything from my phone anyway. This is one of those products that simply gets out of the way and lets you enjoy the music. It's become the streamer I use every day, and I wouldn't hesitate to recommend it to anyone building a modern Hi-Fi system.
