Beautiful audio. Effortlessly.

Twenty is a digital amplifier for your speakers that receives Bluetooth or optical audio streaming from your phone, tablet or computer.

Setting up Twenty is a snap. Connect your speakers to Twenty, pair your phone or tablet to Twenty, and hit Play. Or, use the included optical TOSLINK cable to physically connect your AirPort Express or Apple TV, game console or TV for clear optical audio. For extra low-end, Twenty has a Sub-out to add your existing powered subwoofer.

Twenty’s minimalist design looks good on any surface – next to the stereo, between your speakers, on your desk or entertainment console. The aluminum volume knob is weighted for smooth and accurate volume adjustment.
