PD5
- PREMIUM SWITCHABLE OCTA-DAC CONFIGURATION: Features eight Cirrus Logic CS43198 DACs to deliver extraordinary audio resolution, expansive dynamic range, and class-leading channel separation for capturing every micro-detail.
- INNOVATIVE DUAL DRIVE PLAYBACK MODES: Switch seamlessly between Quad-DAC Mode for efficient, balanced sound (up to 28 hours of battery life), and Octa-DAC Mode to engage all eight DACs for ultimate spatial detail and resolution.
- COLOSSAL 8VRMS BALANCED OUTPUT: Experience desktop-grade power. In Octa-DAC mode, it outputs 8Vrms via the 4.4mm balanced port (and 4Vrms unbalanced), effortlessly driving demanding high-impedance headphones with dynamic scale.
- SMART ENVIROTUNE AMBIENT OPTIMISATION: Uses an integrated microphone to analyze real-time environmental noise, dynamically correcting frequencies to restore obscured audio details without unnecessarily boosting the main volume.
- PROPRIETARY TERATON ALPHA AUDIO ENGINE: Astell&Kern's signature audio solution removes power supply noise, optimizes efficiency, and provides stable, distortion-free amplification to faithfully recreate the original studio recording.
- ENHANCED SIGNAL ALIGNMENT (ESA) TECHNOLOGY: Minimizes group delay by aligning and synchronizing all outgoing signals. This removes phase distortion, delivering a sharp, focused, and coherent audio image.
- INTELLIGENT DIGITAL AUDIO REMASTER (DAR): Upsamples standard digital files (PCM up to 384kHz and lower-resolution up to DSD128) to smooth out the digital edge, revealing a more natural, organic, and analogue-like presentation.
- UP TO 28 HOURS OF BATTERY LIFE: The high-capacity 4,000mAh battery provides up to 28 hours of continuous playback in Quad-DAC mode, with USB PD 3.0 fast-charging restoring full power in just 2.5 hours.
- ERGONOMIC "GRIP CONTROL" DESIGN: Sculpted from lightweight silver aluminium (198g), it features a curved 4.1-inch touchscreen for comfortable, secure, one-handed navigation on the go.
- HIGH-SPEED STREAMING & WIRELESS HUB: Stream seamlessly via dual-band Wi-Fi or Bluetooth 5.3 (LDAC, LHDC, aptX HD). Features BT Sink for direct smartphone streaming, plus full Roon Ready and Qobuz Connect integration.

Quad-DAC
Astell&Kern’s signature sound with a natural and smooth sonic character, optimized for efficient power consumption and extended playback time.
Octa-DAC
delivers extraordinary audio fidelity with an expansive dynamic range and exceptional channel separation.
Offering up to 28 hours of continuous playback, it 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. Weighing approximately 200g with a curved 4.1-inch display that fits naturally in the hand, it delivers exceptional portability and a comfortable grip for effortless listening over extended periods.
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.
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 minimizes frequency distortion and elevates sound quality to be clearer and more pristine.
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.
It may look like an ordinary case at first glance, but no detail was overlooked.
Designed to seamlessly complement the PD5, this 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. Its high transparency preserves the original beauty of the device's design.
While TPU naturally discolours over time, a special UV stabilizer is applied to slow down discoloration and keep the case looking clear and clean for longer.
The design concept of the PD5 is 'Grip Control.' It embodies lightweight portability to seamlessly accompany you anywhere, alongside the sleek, minimalist design identity defining the PD lineup.
Featuring a perfectly balanced feel in hand and a compact form factor, it delivers exceptional grip. The curved 4.1-inch display optimized 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.
