Things to Know
Aiyima T9 Pro

- ⚠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.
Topping PA7 Plus
- ⚠External power brick is massive and can be difficult to hide.
- ⚠Runs warmer than typical Class D amps due to high power density.
- ⚠No remote control (intended to be used with a preamp like the E70).
