Distortion-free Analog Sound of Class-A AMP

Class-A AMPs offer the best linear output, providing soft, warm, and natural sounds by amplifying signals without distortions or defect. This characteristic makes it the most sought-after amplification method by music lovers, though it is considered impossible for portable audio devices as it requires high power consumption and design that is difficult to be realized for small devices.

AK PA10 integrates an Class-A AMP based on the unique circuit design technology of Astell&Kern, offering signature analog sounds.

With a unique circuit design from Astell&Kern that reduces power consumption and increases output while removing noise, AK PA10 is specifically designed to deliver the amazing sounds of an Class-A AMP anywhere and at any time.

AK PA10, the first portable Class-A AMP of Astell&Kern is here so that you can enjoy analog sounds through your portable devices.

AK PA10 controls current to suit different headphones and IEMs reproducing a more intensive and spatial sound.

AK PA10 offers a three-stage control of Class-A AMP current, emphasizing the characteristic of Class-A AMP relative to the current value and creating a more intense sound.

Also, we addressed the concern of battery drain due to power consumption, the major reason why Class-A AMPs are not sued used for portable devices, by controlling the current value.

You can create sounds that suit the characteristics of headphones and IEMs through the three-stage current control option.

We hope you enjoy the textured and spatial sounds that AK PA10’s Class-A AMP can create.

Vivid Sound Output of Gain Control

Sufficient AMP output is required to extract all the subtle nuances in music when played back through varying headphones and IEMs.

When connected to the balanced input, AK PA10 can support up to 6.2 Vrms output at high gain.

Choose the gain level that offers the best sound of the headphone and IEM that you use to enjoy crystal-clear sounds.

AK PA10 brings out the full potential that your audio device
