The Future of Analog Sound, SE300A&futura, carries the spirit of innovation from Astell&Kern, aiming to create products never before seen on the market. The fourth product in the series, the SE300, is equipped with an ultra-fine 0.01% R-2R DAC and a CLASS A/AB dual amplifier system. It adopts Astell&Kern's patented TERATON ALPHA technology and is paired with the brand's first in-house developed FPGA optimization chip. This allows the SE300 to produce a true, linear, and unique analog sound, fully embodying Astell&Kern's technical prowess, strength, and pursuit of sound quality. The SE300's sleek and stylish design perfectly blends with its advanced technology, making it a high-definition music player that values both sound quality and appearance.

In the process of pursuing excellent products, Astell&Kern bravely challenges the limits of material innovation, striving to present the most exquisite works. Not only does it convey the original acoustic effects, but it also integrates infinite creativity from innovative design, aiming at every detail. The SE300 Titanium Limited Edition is crafted from special materials and exquisite craftsmanship. It is a pioneer in material innovation, producing meticulous audio quality through the R-2R DAC and analog amplifier, while also offering a top-notch tactile experience. Explore the SE300 Titanium Limited Edition, bringing Astel&Kern's top-tier analog audio experience to your fingertips. The limited edition set also includes a delicate leather case, providing perfect protection for you.

It is key to total the accurate current value with resistors that has the smallest error ranges in order to create Hi-Fi sound with an R-2R DAC. To realize this, Astell&Kern inspected each specifically selected ultra-precision resistor of 0.01% error range to complete the design of SE300.

For seamless use of sensitive IEMs and hard to drive headphones, a device must provide suitable output, respective of the connected device’s specification.

The SE300 supports a 2-step Gain Level mode to create the prefect match for a wide range of headphones and IEMs, maintaining an optimal sound output.
The two-step gain setting with "Normal" and "High Gain" modes can generate a high current output to create a powerful sound and excellent driver control.
With up to 6 Vrms from the balanced connections, driving high-impedance headphones has never been easier.

The SE300 comes with Astell&Kern’s exclusively developed FPGA and provides optimized OS / NOS modes.

The SE300 uses an FPGA (Field Programmable Gate Array) that we self developed for optimized design instead of using common off the shelf commercial semiconductor chipsets, relaying digital signals to the R-2R DAC through its algorithm. Astell&Kern’s FPGA, developed specifically for the SE300, supports the most ideal OS (Over Sampling) / NOS (Non-Over Sampling).

Enjoy the sound styles reproduced by NOS and OS modes, meticulously designed for the SE300's hardware and programs.

The SE300 comes with a redesigned Crimson-themed UI/UX transforming into a "true music player" for users to deeply connect with their music listening experience.

The new UI/UX is designed so that users can quickly browse music categories and re-discover songs within their music library.
We also added an easy album art search function so that users can re-discover the joy of viewing and interacting with music album art whilst listening to their music.

The crimson theme focuses on edge, simplicity, and dark mode keywords. The color theme of black with red highlights lowers visual fatigue and offers intuitive user experiences, and many other improvements were made to the device’s user-friendliness of app service, artist view, album sorting, and the album art search function.
