Griffin’s Twenty audio amplifier lets you play audio from iTunes and AirPlay-enabled apps to an existing set of speakers using your Airport Express and Apple’s AirPlay wireless protocol. The result is a solution that is an easy to setup streaming audio system powering your speakers via a low-profile, all-digital amplifier.
An awesome gadget with only one drawback: it’s designed around the old Airport Express.
Griffin announced this product at CES back in January (almost a year ago) when the previous generation Airport Express was around. Since then, Apple revised the Express into a new form factor.
It’ll still work and and Griffin even have a video on YouTube on setting it up but a lot of the elegance that it aims to provide is lost.
