Astell & Kern AK120 II

We present "A New Standard in Listening to Music" with the AK100 2nd Generation.


While considering how to improve the AK100, we realized that there was a difference between measured audio specifications and what we felt sounded good. After much deliberation, our development efforts were focused on making the AK100 2nd Generation "feel" right to our senses rather than mechanically boosting technical specs. The original AK100 was developed according to audio specification standards, but development of the next-generation AK100 was developed to the "New Standard" of how the music sounds.
