Our take on the 400W 2-Channel HiFi Stereo Audio Amplifier

This is a compact two-channel class-style mini amplifier in a ribbed aluminum housing with front-panel bass, treble and volume knobs and a blue-lit volume ring. It takes RCA or AUX input from a phone, TV, PC, DVD player or set-top box and drives passive speakers through spring-clip terminals. Its real output is modest: the maker rates it at 20W per channel RMS, with the 200W-per-channel figure being a peak claim, so it suits small rooms, desktops and vehicle or RV setups rather than filling a large home theater. Compared with full-size receivers it is far smaller and simpler, but it lacks a remote, tone presets, Bluetooth and multiple inputs.
