Compact in Form, Infinite in Sound

Engineered for effortless portability, the PD5 delivers music with total freedom and comfort, without ever compromising on performance or sound quality. Designed to fit comfortably in one hand, it combines a compact form factor with all-day battery life. Going far beyond the physical limits of its size, it delivers Astell&Kern's signature deep, detailed and rich sound. Achieving the perfect harmony between portability and high performance, the PD5 brings the ultimate audio experience into your everyday life.

Octa-DAC, Uncompromised Sound

Engineered with an Octa-DAC architecture, the PD5 delivers extraordinary audio fidelity without sacrificing power or precision. The full bank of converters gives the player an expansive dynamic range and exceptional channel separation. Going far beyond conventional signal processing, it unveils the purest sound, capturing even the most subtle musical nuances. Its output is powerful enough to drive demanding headphones with ease, bringing Astell&Kern's true signature sound into complete perfection.

Dual Drive Mode: Tailored to Every Listening Environment

Dual Drive Mode lets you select the optimal DAC configuration for any listening environment or preference, so you can find the ideal balance between performance and power efficiency. Quad-DAC mode delivers Astell&Kern's signature sound with a natural and smooth sonic character, optimised for efficient power consumption and extended playback time. Octa-DAC mode delivers extraordinary audio fidelity with an expansive dynamic range, exceptional channel separation and maximum performance.

Longer, More Convenient Listening

With continuous playback that lasts through a full day, the PD5 allows complete immersion in music without worrying about battery life. Stay focused purely on your sound with a single charge, from long commutes to travel, and all the way until bedtime. Light enough to carry all day and shaped around a curved display that fits naturally in the hand, it delivers exceptional portability and a comfortable grip for effortless listening over extended periods.

Smart Sound that Understands Your Environment

A blend of "Environment" and "Tune", EnviroTune is an intelligent sound-tuning technology that analyses listening surroundings in real time to restore musical details easily lost to ambient noise. The built-in microphone detects changes in ambient noise in real time, analysing input sound by frequency band to automatically compensate for frequencies masked by noise. Without unnecessarily raising the volume, the sound continuously adapts to your environment, allowing complete immersion in the original detail of your music, anywhere, anytime.

Enhanced Signal Alignment and TERATON ALPHA

The PD5 drastically improves group delay, a chronic issue in audio systems, through proprietary ESA (Enhanced Signal Alignment) technology. By aligning frequency signals to arrive with greater uniformity, ESA minimises frequency distortion and elevates sound quality to be clearer and more pristine. Group delay refers to the time difference required for various frequencies to pass through an audio system, which can cause sound signals across different frequencies to arrive at slightly different times rather than simultaneously.

To deliver the ultimate DAP experience, Astell&Kern incorporated its latest converters and further advanced TERATON ALPHA, its Ultimate Sound Solution. Perfected through relentless research, TERATON ALPHA is proprietary audio technology designed to deliver sound closest to the original source through effective power noise removal, efficient power consumption, unwavering amplification and a seamlessly converted audio output interface.

Vivid Original Sound: Digital Audio Remaster Technology

The PD5 features Digital Audio Remaster (DAR) technology, developed to deliver the refined sound of higher sample rates. DAR upsamples the sample rate of played audio tracks to transcend the physical limitations of the original source format. Higher sample rates enable more delicate and precise playback, bringing sound closer to true analogue expression. It vividly reproduces original recordings, allowing you to experience subtle musical nuances and rich sound at an elevated level, and DAR can be switched on or off depending on the playing source and your personal preference.

Sound Design Shaped by DAC Filters

Select from four distinct DAC filters to tailor your personal listening preference, and take full control of your sound characteristics with custom signal shaping. Low Latency Fast shapes a richer low-frequency response through post-ringing decay. Low Latency Slow preserves a pure original sound with subtle natural reverb. Phase Compensated Fast delivers a powerful, dynamic character shaped by balanced pre- and post-ringing. Phase Compensated Slow reveals a natural acoustic texture with light, gentle reverberation.

Crossfeed: A Speaker-Like Experience via Headphones

Crossfeed blends a portion of the original signal from one channel and sends it to the opposite channel with a slight time delay, centring the soundstage. This recreates the natural spatial presentation of listening through loudspeakers while reducing ear fatigue during extended listening. Detailed settings including Shelf Cutoff, Shelf Gain and Mixer Level let you tailor the effect to your preference.

Automatic Volume Adjustment with ReplayGain

ReplayGain automatically normalises track volumes across different music files, ensuring a consistent playback level throughout your playlist without manual adjustments.

Streaming, Wireless and Connectivity

Dual-band Wi-Fi provides enhanced network performance for seamless high-resolution music streaming and Roon Ready integration. The PD5 is a Roon Ready network player: Roon Ready players combine simple setup, daily reliability and support for the highest level of digital audio performance in the industry, and every one of them is certified by Roon to guarantee the same stellar experience regardless of its manufacturer, its price or its features.

With Qobuz Connect, you can enjoy the full Qobuz experience. The feature lets you control your hi-fi music directly from a Qobuz app, switch between devices while your music continues from the exact moment you left off, and control various Qobuz applications with each other. Simply launch Qobuz, press play, and enjoy CD-lossless and hi-res listening at the highest sound quality.

The BT Sink function lets you connect external devices to the player over Bluetooth, much like linking a smartphone to a wireless speaker, and stream high-fidelity music directly to the device from an external source.

Perfect Fit. Natural Feel

It may look like an ordinary case at first glance, but no detail was overlooked. Designed to seamlessly complement the PD5, the bundled case is crafted in South Korea using premium TPU raw materials from Covestro, Germany. The soft, flexible material provides a snug, seamless fit with comfortable button feedback and reliable protection, while its high transparency preserves the original beauty of the device's design. TPU naturally discolours over time, so a special UV stabiliser is applied to slow down discolouration and keep the case looking clear and clean for longer.

Design: Grip Control

The design concept of the PD5 is "Grip Control". It embodies lightweight portability to seamlessly accompany you anywhere, alongside the sleek, minimalist design identity that defines the PD lineup. Featuring a perfectly balanced feel in hand and a compact form factor, it delivers exceptional grip, while the curved display optimised for DAP usage offers effortless readability and tactile control even during long listening sessions. At the top, the microphone for EnviroTune and the power button are symmetrically arranged to achieve balanced aesthetic harmony, integrating functional elements into a single refined structure. Effortless to carry and designed for daily enjoyment, the PD5 is lifestyle audio made to bring hi-fi DAP listening seamlessly into your everyday life.

Finish

The PD5 is offered in a single Silver finish. Its machined aluminium body has a soft, cool metallic tone that keeps the player understated, lets the display carry the colour in the room and settles naturally against both dark and light surroundings. The aluminium construction also keeps the player light enough for all-day carrying while giving the chassis the rigidity the design depends on.
