Things to Know
Aiyima A07 Max
- ⚠Vents are located on the bottom/sides, which is better than the original but still relies on passive convection.
- ⚠Some users report 'sparking' at the DC input jack when connecting power (connect brick to wall last).
- ⚠Aux output is not a true variable pre-out.
Fosi Audio ZA3
- ⚠Frequency response is load-dependent (high frequencies may rise with 8Ω loads due to lack of PFFB).
- ⚠The subwoofer output is full-range pass-through on the main terminals; it does not filter bass from the main speakers.
- ⚠Volume control is defeated in Mono mode, requiring a preamp.
