- ⚠Speaker terminals are very close together; difficult to use with thick cables.
Fosi Audio V3 Mono
- ⚠Chassis gets significantly warm due to the compact thermal design coupled with high power density.
- ⚠Auto-standby feature produces a mechanical 'click' that some users find audible in quiet rooms.
- ⚠Requires two separate power bricks (or a specialized splitter) for a stereo pair, adding cable clutter.
