Astell&Kern A&futura SE300: The future of analog sound

A&futura by Astell&Kern is a product line that reflects the company’s endless efforts in innovation. The SE300 is the fourth model in the A&futura line, which is Astell&Kern’s premium digital audio player , inheriting this identity and expanding its sonic potential with the latest technology.

The A&futura SE300 is equipped with a high-level R-2R DAC, two class A/AB amplifiers based on TERATON ALPHA technology, and the first self-developed FPGA technology. With such unrivaled components, it offers the true Astell&Kern philosophy of sound and technology .



Immerse yourself in the true analog sound produced by the SE300 with Class-A AMP and R-2R DAC technology, for the first time in an Astell&Kern player.

To ensure better analog sound reproduction in the A&futura SE300 audio player, the DAC and AMP sections were combined for the first time during the initial development phase.

The SE300 comes with an R-2R DAC, instead of the Delta-Sigma DAC most commonly used in other audio players. The R-2R DAC, also known as a Ladder DAC because it places resistors in a rung shape, offers a natural yet dynamic Hi-Fi sound, but it is extremely technical and difficult to implement, requiring complex high-precision resistor blocks and difficult-to-control current controllers.



However, despite these technical challenges, after several years of development and testing, the brand’s engineers managed to overcome this and create a new analog sound. In the process, each of the 96 high-precision resistors was selected in detail and the R-2R DAC technology was completed.


The SE300 takes us one step closer to realizing analog sound from a digital source and is the result of the long journey Astell&Kern has taken with unwavering skill to find the ultimate sound solution.



The SE300 comes with dual-amp mode. Class A amplification, which produces low distortion and natural sound, and Class AB amplification, which reproduces dynamic sound with high efficiency, so users can choose between the two amplifiers depending on their preferences and the genre of music they play.

Experience the authentic sounds that only Astell&Kern can deliver with the SE300, which comes with an R-2R DAC and two Class A/AB amplifiers born from Astell&Kern’s unique proprietary designs that reduce power consumption and improve the output signal by removing noise.



For seamless use of sensitive earbuds and demanding full-size headphones , the device must provide an appropriate output signal according to the specifications of the connected device.

The SE300 supports 2-level gain mode to create the perfect sound for a wide range of headphones while maintaining optimal sound output.
