Griffin Previews the Twenty Audio Amplifier for Airport Express at CES


“The Griffin Twenty is the easiest, best-sounding solution for consumers who have speakers that are not AirPlay-enabled but still want to stream high-fidelity audio wirelessly,” said Mark Rowan, President of Griffin Technology. “Not only can users stream from their iTunes library, they can easily connect with any AirPlay-enabled iOS device.”


Twenty boasts a zero-configuration audio set-up that streams Apple Lossless sound from iTunes or any other AirPlay-enabled app (Pandora, Spotify,, etc.) to the user’s speakers via a low-profile digital amplifier. Twenty comes equipped with a power connection and mount for Airport Express. It features a 2.1 channel sound system with 20 watts output per channel and also supports a powered subwoofer with an automatic active crossover at 80 Hz.
