  • The SA700 is the world’s first digital audio player that includes the latest technologies such as dual AK4492 DACs, 32bit/384kHz PCM, and native support for DSD256 playback.

    Building on the classic design of the AK120, the SA700 features a volume wheel that allows users to experience the evolution of Astell&Kern’s signature analog design.

    Inspired by string bridges, the protection ridges and LED lighting around the volume wheel combine to create a classic and lively experience. The LED on the volume wheel goes beyond simple visual effects and serves as an intuitive indicator of information about the song being played and the volume level. 

    Depending on the bit depth of the song currently being played, the LED will light up in different colors of red, green, blue, and purple, and depending on the volume, the color saturation of the LED changes as you raise or lower the volume with 150 levels of color intensity. The display will feature a GUI that embodies the red and orange colors symbolic of Astell&Kern.

    Astell&Kern unveils its newest audio player, the Astell&Kern SA700. The SA700 is a reinterpretation of the first generation AK120, a player that established Astell&Kern as a global leader of portable high-resolution audio over seven years ago. Debuting in 2013, the AK120 was the first portable player in the world to feature Dual DACs, leading the success story of AstellKern with its outstanding space and clear sound.

    “Past Meets Present” with the SA700 as the latest DAC and amplifier design technology is added to the classic design look of the AK120. The new SA700 not only adds nostalgia for the brand, but delivers a deeper and more robust sound, providing users with new sound experiences.
