Powerful tiny Bluetooth amp


"Class-T amplifiers" have been around for over 20 years. They are tiny, cheap, and look like toys. But they sound amazing. I bought a Bluetooth model (Nobsound G3 5.0 Amplifier) and hooked it up to a pair of old speakers. The sound is very clean with zero buzz or distortion. Anyone in my family can play music through the amp right from their mobile phones.
