Griffin's Twenty Audio Amp pairs up with your AirPort Express, enables AirPlay for any 2.1 speakers

Sure, a spendy, AirPlay-equipped speaker is one way to stream lossless audio over WiFi in your abode with iOS or iTunes -- or your could bring your own speakers to the party with Griffin Technology's Twenty Audio Amplifier. It's taken just shy of a year to ship since being announced at CES, but now this $100 Apple-centric HiFi accessory is finally shipping. As a refresher, the Twenty docks with Apple's AirPort Express WiFi router, allowing you to bring the benefits of AirPlay to any 2.1 speakers (left, right and sub channels) you choose to pair it with. Pass-thru power is supplied to your AirPort, sparing the need to plug it into a wall, but its audio connection to the Twenty gets handled by an included TOS-link cable. The Twenty is rated for 40 watts of peak output (20x2) with an active subwoofer crossover at 80hz, and a chunky volume dial adds some analog-esque tactility to setting the overall level.
