Astell & Kern / PD5 Silver

The Astell&Kern "PD5" is a digital audio player that combines an Octa DAC architecture—featuring eight CS43198 DAC chips—with a lightweight, compact aluminum body weighing approximately 198g.

■ Octa DAC Architecture with 8x CS43198 DACs
・ Equipped with eight Cirrus Logic CS43198 DACs, this architecture delivers exceptional channel separation and an expansive dynamic range. It maintains a high signal-to-noise (S/N) ratio, low distortion, and ultra-low crosstalk, while providing a powerful high-output of up to 8Vrms when using a balanced connection.
■ Optimized for Any Listening Environment: Dual Drive Modes
・ Users can seamlessly switch between two modes: "Octa DAC Mode," which utilizes all eight DACs to produce superior resolution and spatial imaging, and "Quad DAC Mode," which enhances power efficiency—ideal for extended listening sessions.
■ Longer, More Comfortable Listening: Up to ~28 Hours of Continuous Playback
・ Thanks to optimized power management technology, the device offers up to approximately 28 hours of continuous playback in Quad DAC mode, and up to 15 hours in Octa DAC mode. Whether you are traveling or commuting, you can immerse yourself in music without worrying about battery life.
■ Intelligent Sound Technology: EnviroTune
・ Featuring a built-in microphone located on the top of the unit, the device detects and analyzes ambient noise in real-time. It then applies intelligent tuning to automatically compensate for frequency ranges that might otherwise be masked by background noise—allowing you to enjoy the delicate nuances of your music without needing to turn the volume up excessively.
■ Full Android OS with Proprietary "ADP" Technology to Overcome SRC
・ The device runs on a full Android OS, allowing for the free installation of various apps. Furthermore, it incorporates Astell&Kern’s proprietary "ADP" (Astell&Kern Direct Path) technology, which bypasses the sampling rate conversion (SRC) limitations inherent to the Android OS, enabling bit-perfect, lossless playback—even when streaming. ■ Perfect Fit and Natural Feel: Includes a TPU Case
・ The device comes with a custom-fit case made from high-quality TPU sourced from the German company Covestro. It offers excellent transparency while ensuring that the buttons remain easy and comfortable to operate. The material is infused with a special UV stabilizer, which helps prevent discoloration over time and keeps the case looking beautiful for longer.
