{"product_id":"astell-kern-pd20","title":"Astell\u0026Kern PD20","description":"\u003cp\u003eThe Astell\u0026amp;Kern PD20 is a reference digital audio player built around a single idea: music shaped to the way you actually hear. Developed with audio-personalization specialist Audiodo, its Personal Sound feature runs a short per-ear hearing test and builds a profile unique to you, then lets you refine it by hand, all on top of a genuine ESS quad-DAC and a multi-mode analog amplifier.\u003c\/p\u003e\n\u003ch3\u003eType and Technology\u003c\/h3\u003e\n\u003cp\u003eA quad-DAC design built on four ESS ES9027PRO converters operating independently to minimize inter-channel interference and deliver precise separation. It decodes PCM up to 32-bit\/768kHz and native DSD512. The headline feature is Audiodo Personal Sound, a first for a DAP: a simple hearing test maps each ear independently and applies a custom correction, with dedicated measurement earphones included for an accurate result.\u003c\/p\u003e\n\u003ch3\u003eSound Character\u003c\/h3\u003e\n\u003cp\u003eBeyond the personalized profile, the PD20 puts tuning in your hands. A Triple AMP architecture offers Class A for rich, dense, analog-like texture, Class AB for balance and efficiency, and Hybrid for the best of both, switched by a physical slide key. In Class A and Hybrid modes the amplifier current adjusts across High, Mid, and Low for finer control of drive and density. The Sound Master Wheel then fine-tunes bass, mid, and treble across 160 steps purely by feel, working on top of the corrected Audiodo foundation.\u003c\/p\u003e\n\u003ch3\u003eBuild and Finish\u003c\/h3\u003e\n\u003cp\u003eMachined from aluminum in a Sound Lab Control design, the PD20 places two wheels on the top deck, one for sound tuning and one for volume, with AMP and current slide switches and top-mounted LED indicators so you can read the current mode at a glance. A 6-inch Full HD display, 3.5 mm single-ended and 4.4 mm balanced outputs, and roughly 14 hours of battery with USB-C PD 3.0 fast charging round out the package. Bluetooth adds LDAC, aptX HD, and LHDC, and BT Sink lets the PD20 act as a wireless DAC.\u003c\/p\u003e\n\u003ch3\u003eBest For\u003c\/h3\u003e\n\u003cp\u003eListeners who want a flagship-class portable source that adapts to their own hearing, and who value hands-on, physical control over EQ and amplifier character, in a player that still measures and performs at reference level.\u003c\/p\u003e\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAstell\u0026amp;Kern PD20\u003c\/li\u003e\n\u003cli\u003eMeasurement earphones (for Personal Sound)\u003c\/li\u003e\n\u003cli\u003eUSB-C to USB-C cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eDAC\u003c\/td\u003e\n\u003ctd\u003eESS ES9027PRO x4 (quad-DAC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDecoding\u003c\/td\u003e\n\u003ctd\u003ePCM to 32-bit\/768kHz, native DSD512\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAmplifier\u003c\/td\u003e\n\u003ctd\u003eTriple AMP: Class A, Class AB, Hybrid (adjustable Class-A current: High, Mid, Low)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePersonalization\u003c\/td\u003e\n\u003ctd\u003eAudiodo Personal Sound (per-ear hearing profile); 160-step Sound Master Wheel EQ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage\u003c\/td\u003e\n\u003ctd\u003e256 GB internal, microSD up to 2 TB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003e6-inch Full HD (2160 x 1080) touchscreen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutputs\u003c\/td\u003e\n\u003ctd\u003e3.5 mm single-ended (optical out), 4.4 mm balanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput level\u003c\/td\u003e\n\u003ctd\u003e5 Vrms unbalanced, 10 Vrms balanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWireless\u003c\/td\u003e\n\u003ctd\u003eWi-Fi 802.11 a\/b\/g\/n\/ac; Bluetooth 5.3 (LDAC, aptX HD, LHDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery\u003c\/td\u003e\n\u003ctd\u003e5,770 mAh, approx. 14 hours; USB-C PD 3.0 fast charge (about 4 hours)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody\u003c\/td\u003e\n\u003ctd\u003eAluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eApprox. 313 g (11.04 oz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWhat Reviewers Say\u003c\/h3\u003e\n\u003cp\u003eMoon Audio explores the PD20's Personal Sound hearing test and hands-on tuning controls, explaining why this approach could become a new standard for players.\u003c\/p\u003e\n\u003cdiv style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;\"\u003e\u003ciframe loading=\"lazy\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;\" src=\"https:\/\/www.youtube-nocookie.com\/embed\/gUFrhvPrjBA\" title=\"Moon Audio reviews Astell\u0026amp;Kern PD20\" frameborder=\"0\" allow=\"accelerometer; encrypted-media; picture-in-picture\" allowfullscreen\u003e\u003c\/iframe\u003e\u003c\/div\u003e","brand":"Astell\u0026Kern","offers":[{"title":"Default Title","offer_id":53592138088727,"sku":null,"price":1970.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0213\/4262\/files\/rep_66f3970e9c9be043abcbb89e58ebcbab0.png?v=1782772390","url":"https:\/\/www.mimic-audio.com\/products\/astell-kern-pd20","provider":"Mimic-Audio","version":"1.0","type":"link"}
