The $30 Amplifier You've Been Looking For

This Wuzhi amp just works. Bluetooth audio is transmitted with absolute clarity. The audio over the 3.5mm jack is just as good as over a wired analogue connection.

There was more than enough power for these 12-watt RMS speakers, but the sound quality just wasn't pleasing no matter how hard I cranked the bass and treble. Another thing I don't like about this amp is that…
