Launched last year around October in Japan the AK100 is Iriver most “poweful” DAP yet and designed for music aficionados :

“Beside a rather luxurious and elegant design the Astell & Kern AK100 is in fact oriented to music lovers and people looking for the the best audio quality possible, indeed the Astell & Kern AK100 is fully compatible with 24bit/192kHZ FLAC & WAV audio tracks alongside the usual APE/MP3/WMA/OGG support. To achieve such quality the Astell & Kern AK100 comes with Woflson WM8740 powerful DAC offering an output of 110bB on a 10Hz to 20kHz range.”

While only available so far in Japan in “Black”, Iriver announced however their plan to launch two new limited versions of the AK100 with a Silver and Gold one. Both models will be sold around 54,800 Yen in Japan starting from today!
