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.
SMSL AL200
- ⚠Lack of a subwoofer output or pre-out is a major omission for a 'hub' device.
- ⚠The display font is small and can be hard to read from a distance.
- ⚠Some users report a slight 'pop' sound when switching inputs.
