Limitations and Recommendations
While I found the Fosi Audio ZA3 to be an impressive amplifier, it does have a few limitations worth noting.
The subwoofer output sends a full signal to the speaker outs, which can overwhelm smaller speakers. I recommend using a preamp to control this better.
Additionally, while the sound quality is clear, some users mention a shallow soundstage and less powerful bass compared to larger amplifiers. If you’re looking for deeper bass, you might want to examine those options.
