    Simple and feature packed quality streamer

    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.

    Great streamer with solid sound

    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.

    Great value for a small package!

    The S3 has been a great addition to my home theater. It was very easy to set up (using the free app) and with a single tosslink cable (provided) it was easy to integrate. I love the ability to connect to Tidal and also to my iPhone through AirPlay 2. It has not been certified with Roon, so Roon is not available at this time. For that reason I give it four stars. Once Roon is available, I might change my review.

    FosiAudio S3 helping to tie my home audio together

    The Fosi Audio S3 has worked very well in my computer audio setup. The S3 has a built in eArc that I will eventually hope to use when I buy speakers for my TV. I do wish that the device had a built-in USBC for whatever function. There is an app that is available for the device that helps link it with your streaming music choice. It does come with a toslink cable that I am using to connect to my current audio setup. When I stream music through the device it still sounds just as good as if I would have natively done it either on my PC or on my iot smart speakers
