Evolution Emotion and Pleasure: the Astell &Kern AK120 II

Since Astell&Kern’s initial unveiling of the Dual DAC-capable AK120 in May 2013, both sound resolution and affinity have been improved with the AK120 II.

The former flagship model, AK240, has been highly regarded for delivering mastering level quality instrumentals with its improved Dual DAC and analogue amplifier circuit system. The AK120 II allows you to experience the highest sound quality by directly inheriting the sound design structure implemented in the AK240.

With the AK120 2nd Generation, we aimed for the perfect harmony of engineering and design. From beginning to end, we re-examined the PCB layout, the form factor, the materials, and the post-manufacturing process.

Re-examination of the volume wheel’s position.

We relocated the volume wheel to the top to maximize the space for the battery. We also redesigned the volume wheel for further convenience and easier usability even when you hold the product with both hands.

Redesign of the volume wheel and guard.

The AK120 2nd Generation’s volume wheel consists of two parts: the head and the root. The head is the knurled part and control the volume wheel by holding it securely. The root is the base of the volume wheel and wrapped in a guard that’s directly connected to the hardware. This division into two parts enhances the usability and stability of the AK120 2nd Generation, while the distinguished parts also provide further protection for external damage.

The AK120-II is a Class-Leading Digital Audio Player

We added the CS4398 Dual DAC and the balanced output method with sound quality proven through our flagship model.

The AK120 2nd Generation provides the weighty sound through the CS4398 Dual DAC and the A-amp, while providing delicate melodies through the balanced output.

The unbalanced method is the most commonly used basic method which consists of “left and right signals + ground line”. This setup includes a ground line which blocks out external noises from the outside. However, since the ground line cannot block out all of the external noises completely, external noises can be mixed into the signals that are transmitted, which then result in changes to the sound. The longer the signals travel, the more external noises that will be mixed into the sound which is why it is used within a short distance of 1 to 2 meters.

Unlike the unbalanced method, the balanced method has an additional cold signal to compliment the hot signal which reduces the external noises.

We got familiarised with the DSD format because of the AK120. However, because of the limited hardware functionality, the AK120 could only support DSD up to 2.8MHz with PCM conversion / downsampling to 88.1kHz. Thanks to the advanced hardware functionality and the DSD to PCM software, we can now provide playback support of DSD up to 5.6MHz.

The AK120 2nd Generation includes the USB DAC feature.

Connect the AK120 2nd Generation to a PC or Mac and use it as a USB DAC that also supports DSD. With a Dual DAC and the USB DAC feature, enjoy a richer resolution in sound that goes beyond the limitations of the sound card installed in your computer.

With the AK120 2nd Generation, you can now skip the complicated process of searching for music files, connecting to the PC, and downloading the files to the player. Simply connect the AK120 2nd Generation to your music collection on your computer in the same network to download and/or stream music!.
