Good but not as a preamp

Sound is great with AKM DAC chip.
I was planning to use it as a combined DAC/ preamp with the possibility to have bass and treble control. As you all know different recordings needs sometimes to be adjusted in bass and treble. Unfortunately you can not use bass and treble control when in rca out mode. I could send it back and get a refund. The Fosi support is very friendly.

Great headphone Amp!

I have the Fosi ZH3 connected to my P4 pre-amp and I'm very impressed with the high sound quality this pair produces on my headphones. The ZH3 delivers enough power to drive the FiiO FT3 headphones @ 350 ohms, the volume it reaches is more than enough for music enjoyment. I upgraded the stock OP amps to the Muses02, since the specs on the Muses are better than most stock OP amps. The tone control is always a feature that I'm up for and I appreciate Fosi for including tone controls on a lot of its products. I don't use the ZH3 as a DAC since I have quite a few portable DAC/Amps and I like changing the DAC source to try different sound flavors. With the ZH3, Fosi Audio has delivered another fantastic and budget friendly product. Cheers!

It’s a decent unit that performs as expected in my fosi stack. The DAC sounds about as well as the one on my WiiM and the filters don’t really change the music much. The headphone amp is better than average.
