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. Astell&Kern's first step in this journey was to start from the very beginning. Rather than creating a successor to the PD10, they 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.
Quad-DACs
Designed with a singular focus on sound quality, PD20 adopts the ESS ES9027PRO DAC in a Quad-DAC configuration. Four DACs operate independently to minimize inter-channel interference and deliver precise signal separation. As a result, even the finest nuances in sound are revealed with greater clarity, creating a natural, analog-like presentation through clean, distortion-free layering.
TERRATON ALPHA
To create the ultimate DAP unlike anything experienced before, A&K further evolved and applied TERATON ALPHA, their Ultimate Sound Solution, incorporating its advanced and innovative audio technologies. Through effective power noise reduction, efficient power consumption with stable amplification, and a precisely engineered audio output interface, it delivers sound that remains faithful to the original source.
Triple Amp Architecture
PD20 features three distinct amplifier classes, allowing you to directly choose both sonic character and driving performance. Switching between amplifier classes is achieved through a physical slide key rather than a software menu, enabling intuitive, immediate control based on your listening situation.
Class A mode delivers rich, high-density sound with minimal signal distortion, expressing a smooth, analog-like texture. Class AB mode offers excellent balance and efficiency, providing stable dynamics and articulate detail. Hybrid mode combines the refined texture of Class A with the efficiency and power of Class AB, creating a new level of sonic balance.
Sound Tuned to Your Hearing
Developed in collaboration with global audio solution leader Audiodo, Personal Sound is used in a DAP for the first time, creating a personalized profile exclusively for you and redefining how you experience sound.
By precisely analyzing your hearing characteristics and independently compensating for left and right ears, it dramatically enhances clarity and balance. Regardless of genre, volume level, or the headphones or IEMs you use, you can enjoy a consistently optimized listening experience.
Sound Master Wheel
The Sound Master Wheel, a key design element of the PD20, is seamlessly integrated with the Audiodo equalizer. Each band—Bass, Mid, and Treble—can be finely adjusted across 160 steps, from –8.0 dB to +8.0 dB, allowing even the most subtle preferences to be precisely reflected in your sound. Without interrupting your music, you can shape and refine the sound purely through the tactile feel of the wheel.

- do be aware of additional import tax/VAT that may apply.
Due to recent changes in U.S. trade regulations, additional tariffs are being imposed on products manufactured in China and imported into the United States. As many of our audio products are made in China, orders shipped to U.S. addresses may be subject to an added tariff charge at checkout, reflected as a "U.S. Import Tariff Surcharge". Please note that this surcharge amount is determined by U.S. import policies and may vary significantly depending on product categories and any future policy adjustments. These charges are necessary to ensure compliance with U.S. customs requirements and to allow us to continue serving our U.S. customers reliably. We strongly encourage you to review the total cost at checkout before placing your order.
This surcharge is temporary but necessary during this period of significantly increased operational pressure as a result of the ongoing geo‑political situation in the Middle East.
Orders shipped to Gulf Cooperation Council (GCC), Africa, US and EU regions may be subject to an added surcharge at checkout, reflected as a "Temporary Emergency Situational Surcharge". Please note that this surcharge amount is determined by our freight partners, and may subject to adjustments according to situational updates. We strongly encourage you to review the total cost at checkout before placing your order.
