Posted some great benchmarks, surpassing many of the Wiim products.

Fosi is just waiting for Roon to officially certify the device

Streamers will play all your ripped CDs, mp3s, Tidal, Spotify or whatever, at maximum resolution, without being interrupted if your phone rings (great for when you have guests over, or need the bluetooth on your phone to run the BBQ or sous vede )


Balanced Connectors are immune to 'ground loop' hum


The DAC chips are better than those in your phone, receiver or CD player


Prevents guests from hijacking your bluetooth and playing Kid Rock.

Guess I am getting old...

"The new FOSI S3 streamer has BALANCED outputs, support for ROON, Tidal, Qobuz, Airplay..."

In my vernacular, FOSI is a Russian warez group, and Airplay is a wifi hacking prorocol...

The rest are nonsensical...

Dang!

This runs off WiFi. Why would you use Bluetooth?

As an example, I used to connect my TV to my stereo, it casts Bluetooth and not WIFI

"Balanced" yet uses RCA connectors/cables which almost always are single ended or ground referenced.

I am almost ready to pull the trigger on this. Looking for a good preamp that has balance out that will be hooked up to my emotiva xpa 2 amp. Streaming and the Akm makes it a fantastic solution. Any concerns from anyone on the use of this particular device as opposed to some other options out there?

Seems a neat device, but I already have half a dozen Chromecast Audio devices that perform the main function of this.
I may like it for a dedicated stereo listening setup with the ZA3 amp...but I'd be bothered by the mismatched silver/black stack.

Strangely, Fosi does not appear to offer a user manual so I could not verify if it has bass management or not. https://fosiaudio.com/products/s3...i-streamer

If it does not have bass management, hard pass. The only clear advantage I can see about this product over the Wiim Ultra is the XLR outputs, which are handy IF you are using powered speakers with XLR inputs such as the JBL 305/306/308p.

According to Fosi, the manual is almost done.

Full bass management is coming in the next software update; so don't order until it's been deployed if your sub does not offer the controls you require.
