Things to Know
Aiyima A70
- ⚠Volume taper is extremely aggressive; it gets very loud very early on the dial.
- ⚠The subwoofer output is active but does not high-pass the main speakers.
- ⚠Heat dissipation is passive and the case can become uncomfortable to touch during extended high-output sessions.
Fosi Audio MC101
- ⚠Uses the older, noisier TPA3116 chip (higher noise floor than V3/A07).
- ⚠Bluetooth only supports SBC/AAC (no AptX/LDAC).
- ⚠Speaker terminals are very close together; difficult to use with thick cables.
