Griffin’s new Twenty gizmo allows you to turn any pair of stereo speakers into an AirPlay-ready streaming station.

The Griffin Twenty includes a built-in 20wpc 2.1 amplifier and a mains power dock for an Airport Express, so you just need to plug in a pair of speakers (and a subwoofer too, if you like) using standard speaker cables.

You can then wirelessly stream music from PC, Mac or mobile device like the iPhone or iPad using iTunes, anywhere in the home.

It also has a digital optical input for connecting to the Airport Express as well as a power port.
