TERATON ALPHA
Great headphone Amps generate true and pure sound reproduction, when not only a stable output is realized, but also when each and every component from power, noise, signal transition, and circuit structures 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, an AK Ultimate Sound Solution allowing for playback of ultra-high quality sound without any distortion.
Engineered through many years of endless research, Teraton Alpha is A&K's unique technology designed to produce audio playback as close as possible to the original sound through effective power noise removal, efficient power management, unwavering amplification, and a fully converted audio output interface.
Distortion-free Class-A Amp Analog Sound
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. However, it is considered impossible for portable audio devices due to its high power consumption and larger footprint design requirements.
PA10 integrates a Class-A Amp based on unique circuit design technology of Astell&Kern, offering signature analog sounds. It's the first Astell&Kern portable Class-A Amp, designed so that you can enjoy analog sound through your portable devices.
