A few years ago Griffin launched the original Twenty, a small digital amp that used an AirPort Express to turn any set of passive speakers into a wireless system for streaming music. Unfortunately for Griffin, shortly after the launch of the Twenty, Apple updated the design of the AirPort Express, which instantly antiquated the digital amp. Now, thanks to advancements in Bluetooth technology, Griffin no longer needs to lean on Apple's AirPlay technology for streaming, and is back with a new and improved version of the
Twenty Digital Amp. We have spent some time with the updated digital amp -- see what we thought about it in our
full review.
