Hi-Fi in Your Pocket:

Like most people, you probably travel. Sadly, most audiophile gear doesn’t travel well. That’s why iRiver made the Astell & Kern AK100. This is a 24Bit/192Khz WOLFSON DAC featuring MQS (Mastering Quality Sound) wrapped in black aluminum. The result? Incredible portable sound. Once you add it’s line output and two microSD card slots, you’ve got a full featured, portable, memory expandable, audiophile listening suite. Finally, the AK100 also supports bluetooth 3.0 allowing you to connect bluetooth headphones and speaker.

How’s it Sound?

iRiver's Astell and Kern line is universally renowned for their high sound quality and the AK100 is where that reputation started.The Wolfson DAC does a great job decoding your high resolution files producing mastering level sound quality. With a fully adjustable EQ, the AK100 comes with a neutral balance that you can alter to create your favorite sound signature. The AK100 is optimized for highly sensitive IEMs like the UE900 but it works just as well with low impedance headphones like the Denon D7000.
