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.
 
The first DAP to support personalized sound through a hearing test
160-step EQ control via the Sound Master Wheel
Triple AMP Class with real-time switching
Class A current control with High / Mid / Low modes
Proprietary ESA (Enhanced Signal Alignment) technology to minimize group delay
Advanced DAR
 
Exceptional resolution and high-purity sound, ES9027PRO Quad-DAC
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.
 
Minimizing Group Delay with Proprietary ESA (Enhanced Signal Alignment) Technology
Through its in-house developed ESA (Enhanced Signal Alignment) technology, PD20 significantly improves one of the fundamental challenges in audio reproduction—group delay. ESA precisely aligns frequency signals so they arrive more uniformly, minimizing frequency distortion and enhancing clarity and cleanliness of sound.
