Fosi Audio S3 Balanced HiFi Streamer

Amazing for my setup—I plugged in my TV, my JBL 306P monitors, and my JBL subwoofer. Planning to add a Merak CD player, and in the future, a turntable. Perfect for all use cases. Just waiting for the room correction feature!

Good streamer, but

I’m very pleased with the streaming performance of the S3. I don’t use the preamp capabilities because it’s not sufficiently versatile and doesn’t have balanced outputs - so I use a separate preamp. Then Fosi released a version without the preamp at a lower price so Inwoukd have saved money if I’d delayed my purchase by a couple of weeks. The remote, with its tiny buttons and markings, is hard to read and use.

Compact and hard hitting performance

The S3 is quite the surprise. It outclasses the WiiM Pro Plus or WiiM Ultra. But things jump up to a noticable degree with I swapped out the stock switching power supply with a Linear Power Supply, and even further capacitor filter bank. We are talking inexpensive but good products $100cad each to keep it in value proposition territory. Very impressive sound connected to a pair of Genelec G3 monitors. Hats off to the Fosi Team. I won't say giant killer because it's a misleading vague expression. But clearly this is a great inexpensive product. Buy it!
