Things to Know
Fosi Audio ZA3
- ⚠Frequency response is load-dependent (high frequencies may rise with 8Ω loads due to lack of PFFB).
- ⚠The subwoofer output is full-range pass-through on the main terminals; it does not filter bass from the main speakers.
- ⚠Volume control is defeated in Mono mode, requiring a preamp.
Loxjie A30
- ⚠Low power output compared to Fosi/Aiyima; not suitable for insensitive speakers in large rooms.
- ⚠Headphone output impedance is high, which can alter the frequency response of low-impedance headphones.
- ⚠USB input is limited to 16-bit/44.1kHz (no high-res support via USB).
