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 TB10D (Upgraded)
- ⚠Volume control is logarithmic but very sensitive; gets loud at the 9 o'clock position.
- ⚠Tone controls lack a center detent, making it hard to know when you are truly 'flat'.
- ⚠DC input spark is common when plugging in the power supply (connect to amp first, then wall).
