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.
Willsenton R8
- ⚠Bias drift is common; owners need to check and adjust bias frequently during the first few months.
- ⚠Stock preamp tubes (6SN7/6SL7) are often noisy or microphonic; immediate replacement is recommended.
- ⚠Extreme weight makes shipping it back to China for warranty claims financially impossible.
