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.
