Astell & Kern
The manufacturer Astell & Kern based in Seoul (South Korea) develops and builds compact media players in the high-end audio sector! The latest knowledge is consistently implemented in the software and sound conversion (DAC) - always with the aim of achieving the best possible sound quality.
These high-tech portable players have nothing in common with conventional MP3 players - except that they can also play MP3 if you really want to. High-quality audio formats such as flac, wav and similar container formats as well as MQA decoding are the real core business of these audiophile, portable devices.
The headphones from Astell & Kern are optimally adapted to the players and implement the sound on the same Nevau as is handled by the players and DAC!
