Astell&Kern, a global leader in portable high resolution audio players and accessories, launches the PD20, a new product that redefines the digital audio player by creating a sound signature uniquely tailored to the user’s hearing. Designed under the concept “Craft Your Sound,” the PD20 is not a successor to the popular PD10 or any other Astell&Kern DAP, but an entirely new player built from the ground up; designed to transform how music is individually experienced. Rather than simply delivering sound, the PD20 shapes it to fit the listener.

The PD20 is the first digital audio player to support personalized audio through a built-in hearing test. Developed in collaboration with global audio solutions leader Audiodo, the Personal Sound system analyzes individual hearing characteristics and compensates independently for left and right ears to create a uniquely tailored listening profile. With the included dedicated earphones for precise hearing measurement, users can complete a simple hearing test and immediately experience a sound signature optimized exclusively for them.

To further customize the sound, the PD20 features a Sound Master Wheel, offering 160-step EQ control from –8.0 dB to +8.0 dB across Bass, Mid, and Treble bands, allowing precise real-time audio refinement without interrupting playback.

At its core, PD20 incorporates the ESS ES9027PRO in a Quad-DAC configuration, with four DACs operating independently to minimize inter-channel interference and enhance signal separation.

Astell&Kern’s proprietary ESA (Enhanced Signal Alignment) technology further minimizes group delay by precisely aligning frequency signals, reducing distortion and improving clarity.

Advanced DAR, Astell&Kern’s second-generation Digital Audio Remaster technology that first debuted on the flagship SP4000, is designed to deliver a more natural and refined sound. Rather than sending the audio signal directly to the DAR engine, the signal first passes through VSE (Virtual Sound Extender), where lost harmonics are virtually restored to enhance sound quality. After this initial enhancement, DAR processing is then applied for a more complete upsampling. Through this process, listeners can experience a deeper, more immersive sound that remains faithful to the original recording.

The PD20 integrates Audiosphere technology that goes beyond conventional 2-channel stereo, delivering a powerful sense of spatial immersion. It expands two-channel audio into a virtual three-dimensional sound field and offers four presets: Subtle, Balanced, Immersive, and Echoic.

From the expansive resonance of orchestral performances to the realism of video content, you can select the sound atmosphere that best suits your listening preference.

The player includes 256GB of internal memory with support for microSD cards up to 2TB, dual-band 2.4/5Ghz a/b/g/n/ac Wi-Fi, DLNA networking, USB digital audio output, USB-C for data transfer and charging, and the ability to use the PD20 as a USB DAC for your Mac or Windows-based PC. The PD20 supports native playback of high-res PCM music up to 32-bit, 768kHz and DSD512 and is equipped with a 6-inch FHD+ display.

ReplayGain keeps playback levels consistent across tracks, while AK File Drop enables seamless, wireless file transfers from devices on the same network—no cables required. The PD20 expands wireless audio options with support for aptX™ HD, LDAC™, and BT Sink mode, allowing it to function as a high-quality Bluetooth DAC for music from external devices. With support for USB PD 3.0 fast charging, PD20 can be fully charged in approximately 3.5 hours. For more natural, speaker-like listening, the Crossfeed feature blends left and right channels with adjustable parameters—Shelf Cutoff, Shelf Gain, and Mixer Level—to reduce fatigue and tailor the effect to your preference. The PD20 will be Roon Ready, pending testing and certification by Roon Labs.

The PD20 was designed as a true sound lab. Built around the concept of “Sound Lab Control,” the PD20 mirrors professional studio equipment in both function and design. Dual top-mounted wheels separate sound tuning from volume control, reinforced by slide switches for AMP and CURRENT selection. LED lighting provides real-time track bit-depth indication and visual confirmation of active modes.

With PD20, music is no longer something you simply hear. It is something you shape for your own personalized sound. Through precision engineering, personalized calibration, and intuitive hardware control, the Astell&Kern PD20 establishes a new benchmark for high-resolution portable audio.

The PD20 will be available at authorized Astell&Kern dealers worldwide in March 2026 for $1,800 ($1,970 in the US market).
