In the pursuit of pure musical essence, the journey begins with discovering a sound that truly resonates with you. Astell & Kern’s new PD20 portable digital audio player is engineered precisely for this purpose guiding users toward a deeply personal and transformative listening experience.
Rather than iterating on previous models like the PD10, Astell & Kern has built the PD20 from the ground up as an entirely new device. It shifts the paradigm from passive playback to active sound sculpting, empowering listeners to shape their music like never before.
Personal Sound: Tailored to Your Unique Hearing
The PD20 introduces groundbreaking Personal Sound technology, developed in collaboration with global audio specialist Audiodo. This first-of-its-kind feature conducts a built-in hearing test (using included earbuds for precision) to analyze your individual hearing profile, compensating independently for left and right ears.
The result is a custom sound signature optimized specifically for your hearing characteristics revealing nuances you may have been missing and delivering a more natural, engaging presentation. From there, refine it further to your exact taste with the innovative Sound Master Wheel, a tactile control offering 160-step EQ adjustments across Bass, Mid, and Treble bands (±8.0 dB). This dual-wheel layout separates tonal tuning from volume, allowing real-time tweaks without pausing playback. Music evolves from something you hear into something you actively craft.
Exceptional Resolution with ES9027PRO Quad-DAC
At the heart of the PD20 lies a singular obsession with sonic purity: the ESS ES9027PRO DAC in a Quad-DAC configuration. Four DACs operate independently to eliminate inter-channel interference, ensuring precise signal separation and extraordinary clarity.
Even the subtlest details emerge with lifelike precision, creating layered, distortion-free sound that feels analog in its natural warmth and depth. Astell & Kern elevates this foundation with an advanced iteration of its proprietary TERATON ALPHA technology an integrated suite of audio engineering innovations refined through years of research.
TERATON ALPHA delivers ultra-low power noise, efficient stable amplification, and a meticulously tuned output interface, preserving the integrity of the original source with unmatched fidelity.
Triple AMP Architecture: Choose Your Sonic Character
The PD20 stands out with its Triple AMP system, offering three distinct amplifier classes for direct control over both tonal character and driving power.
- Class A mode provides rich, high-density sound with minimal distortion, delivering smooth, analog-like textures ideal for nuanced, emotive listening.
- Class AB mode strikes an excellent balance of efficiency and performance, ensuring stable dynamics and articulate detail across demanding tracks.
- Hybrid mode merges the refined warmth of Class A with the power and efficiency of Class AB, achieving a new level of sonic equilibrium.
Switching modes is effortless via a physical slide key no menus required for instant adaptation to your music, headphones, or environment.
Adjustable Class-A Current for Ultimate Fine-Tuning
In Class A and Hybrid modes, users can adjust the amplifier current across three levels: High, Mid, and Low. This goes beyond basic output control, precisely tuning energy density and driving behavior to match your earphones or headphones.
Whether seeking maximum drive for power-hungry cans or refined subtlety for sensitive IEMs, these adjustments allow deeper personalization of sound quality and performance.
The Astell & Kern PD20 redefines the high-end portable audio landscape with its blend of cutting-edge personalization, flagship-grade audio engineering, and intuitive physical controls. Housed in a premium aluminum chassis with a spacious 6-inch FHD+ display, it supports up to 32-bit/768kHz PCM, DSD512, 256GB internal storage (expandable to 2TB via microSD), and versatile connectivity including balanced/unbalanced outputs.
