Astell&Kern PD20 Digital Audio Player

Description

Craft Your Sound

Finding the sound that truly suits you is the first step toward the essence of music. PD20 is designed to guide you on that journey.

Our first step in this journey was to start from the very beginning. Rather than creating a successor to the PD10, we created an entirely new audio device that will redefine your musical experience.

Through Personal Sound, you can create a sound signature tailored to your hearing, then precisely refine it to your taste using the Sound Master Wheel. An intuitive control that allows even the amplifier driving mode to be changed with a single touch. Now, music is not just something you listen to. It is something you shape.

160-step EQ control via the Sound Master Wheel

Triple AMP Class with real-time switching
