The Griffin Twenty streaming audio device turns any Apple AirPort Express into a stereo system. The machine has a simple and elegant design, just a plug for the AirPort Express and a large, friendly white dial for volume. As its name implies, the Twenty has an internal 20-watt amplifier and outputs for left and right stereo speakers, plus a subwoofer. The concept is that the dial controls the volume, while the rest of the interface is taken care of through your iPhone, iPad or computer.
