Astell&Kern PA10 Portable Headphone Amplifier Astell&Kern

The First Class-A Portable AMP by Astell&Kern
Astell&Kern has been researching and developing AMP technology to deliver the pure original sound of audio. AK PA10 is the first AK model to introduce a Class-A AMP based on Astell&Kerns know-how in AMP circuit design technology, and it offers the natural and spacious analog sound of Class-A AMP enhanced further with our proprietary TERATON ALPHA technology. Enjoy the pure analog sound of Astell&Kern with AK PA10’s Current / Gain / Crossfeed options for digital audio players and source devices.

TERATON ALPHA, The Essence of A&K Audio Technologies
Great headphone AMPs generate true and pure sound reproduction, when not only a stable output is realized but also each and every part from power, noise, signal transition, circuit structures, etc., are carefully designed and implemented. AK PA10 is small enough to be portable but operates seamlessly with a wide variety of headphones and IEMs, and is enhanced with the addition of TERATON ALPHA technology which is an AK Ultimate Sound Solution allowing for playback of ultra-high quality sound without any distortion. TERATON ALPHA, engineered through many years of endless research, is Astell&Kern’s unique technology that has been designed to produce audio playback that is as close to the original sound through effective power noise removal, efficient power management and unwavering amplification, and a fully converted audio output interface. AK PA10 was developed as the sound solution of TERATON ALPHA, creating pure and intensive analog sounds.

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.

Class-A Current Control Intense and Spatial Sound of Analog AMP
Headphone AMPs are not just designed to get the output required to operate headphones. 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.
