Astell&Kern. Premium High-Resolution Audio Players from South Korea
Astell&Kern is a South Korean luxury audio brand founded in 2013 by iRiver (now Dreamus), renowned for its high-resolution portable music players, headphones, and digital audio systems. With a mission to deliver sound true to the original recording, Astell&Kern pioneered the MQS (Mastering Quality Sound) standard and developed its proprietary TERATON ALPHA audio technology.
From iconic early models like the AK100 and AK120 to current flagship devices such as the A&ultima SP3000, KANN Ultra, and the A&norma SR series, the brand combines cutting-edge engineering, refined all-metal design, and modern connectivity (Wi‑Fi, Bluetooth, USB DAC, and streaming apps).
MQS stands for Mastering Quality Sound, referring to lossless audio files in 24-bit/44.1–192 kHz, offering up to 6.5x more detail than CD quality.
They are designed for demanding audiophiles and music lovers seeking high-fidelity portable audio with no compromises.
A&ultima: premium flagship players with CNC-machined metal bodies.
A&futura: innovation-focused series with advanced technology.
A&norma: accessible Hi-Fi performance for everyday use.
KANN: high-power portable players for demanding headphones.
Most models include balanced outputs (2.5 mm / 4.4 mm), USB DAC, Wi-Fi, Bluetooth, HDMI, and native support for streaming apps. High-end models like the KANN Ultra weigh over 300 g.
All devices are designed, engineered, and manufactured in Seoul, South Korea, by the experienced team behind iRiver/Dreamus.
