Astell&Kern SP4000은 이렇게 만들어졌습니다

We've prepared a video documenting the development journey of Astell&Kern's flagship DAP, the SP4000. We've recreated the countless challenges and struggles that went into creating this ultimate product. This video was produced in English, Japanese, and Chinese for screening at international audio shows prior to the SP4000's official launch. The Korean version will be released exclusively on our channel. (Produced by Royal Typewriter) ※ This video was produced with the support of Astell&Kern.
