Its a DAC/Amp with a rechargeable battery AND a crossfeed in a very thin case. For only $169! The full specs are on the site. Op-amp is a AD8610. DAC is a Texas Instruments PCM2706.
well, if you look at the dimentions you can see that it is a little thicker and wider but shorter in lenght than the arrow - so wouldn't really call it "mini arrow" :P
But it is pretty amazing that it has a build in DAC as well!
Nice! Keep us posted. If that had a clip on it, oh my. No pun intended.
