Our take on the HiFi Stereo Bluetooth 5.0 Digital Power Amplifier Audio Receiver USB 50W+50W

This is a compact stereo amplifier and music player built around the TPA3116 chip, rated at up to 50W per channel into 4-16Ω passive speakers. It takes RCA, AUX, USB, Bluetooth 5.0 and TF card input, and plays WAV, APE and FLAC lossless files from USB drives and cards. It suits a desk, shelf or small room setup where you want to power bookshelf speakers from a phone, TV or computer without a full receiver. Against budget mini amps it stands out on input variety and the TPA3116 board; the trade-offs are that no power supply is included and card playback is limited to random play or left/right key selection.
