Things to Know
Aiyima T9 Pro
- ⚠VU meter sensitivity is not adjustable; barely moves at low volumes.
- ⚠The tube stage adds measurable distortion (2nd harmonic), which is intentional for 'flavor' but not high-fidelity.
- ⚠Runs quite warm due to the tubes and internal DAC.
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.
