Fosi is a great little amp that can put many multiple thousand $$$ to real shame.
The TPA3255 which is a heart of this amplifier is my favorite D-class Amp chip. It's dynamic, fast and tight, but also has the most wonderful midrange that I like even more than most class AB amps.
So how about upgrading it with one of the finest Op-amps - Sparkos Labs SS3602. This is a fully discrete op-amp and the combo is amazing. Whats better than me saying it ? You being able to hear it yourself.
In this video I added an extensive sound demo of the Fosi ZA3 with standard opamps and with Sparkos Labs SS3602. Over 20 minutes of sound demo for you accross different genres so that you can enjoy and make up your mind :)
