Fully Discrete 24bit R-2R DAC
To ensure the A&futura SE300 audio player better reproduces analog sounds, we set out to combine the DAC and AMP sections for the first time during the initial design phase.
The SE300 comes supplied with an R-2R DAC, instead of a Delta-Sigma DAC that is most commonly used in other audio players. R-2R DAC, also known as Ladder DAC, as it arranges resistors in a ladder form, offers natural yet dynamic Hi-Fi sounds, but it is extremely technical and difficult to execute as it requires complex refined resistor units and hard to manage current controls.
However, despite these technical challenges, after several years for development and a lot of trial and error we have managed to overcome this and create a new analog sound. In the process, we have meticulously selected each and every one of the 96 ultra-precision resistors and finalized our R-2R DAC technology.
SE300 takes us one step closer to realizing analog sound from a digital source and is the result of a long journey taken by Astell&Kern with uncompromising craftsmanship to find the ultimate sound solution.
Realization of 24-bit Decoding with R-2R DACThe R-2R DAC within the SE300 arranges 48 pairs (23xR and 25x2R) of 96 ultra-precision resistors to create analog signals, in turn realizing true Hi-Fi 24-bit decoding.
Ultra-precision resistor Design, the Key to Hi-Fi SoundIt 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.
Ultra-precision TCR10 SpecificationsTo create Hi-Fi sound without distortions within such an extreme precision design, we analyzed and preconceived any potential impacts that may be caused by changes in temperature. The SE300 comes with special *TCR10 specifications to minimize the changes in the 0.01% resistor error range.
* TCR10: 10 ppm/℃ Low Temperature Coefficient of resistor
Supporting Class A/AB Dual AMP Mode
The SE300 comes with a Dual AMP mode. Class A amplification that creates low distortions and natural sounds and a Class AB amplification that plays dynamic sounds with high efficiency so users can pick and choose from the two amps according to their listening preferences and genre of music that they are playing.
Experience the true sounds that only Astell&Kern can deliver with the SE300 that comes with an R-2R DAC and Class A/AB Dual AMPs born from Astell&Kern’s unique proprietary designs that reduces power consumption whilst enhancing output and removing noise.
Class A AMP is an analog amp that offers the best linear output, amplifying signals without distortion or loss of signal and providing soft, warm, and natural sounds. The refined analog signal created directly by the R-2R DAC, reproduces a sound closest to the original analog audio through the organic and powerful Class A AMP.
Class AB AMP is an analog amp that offers a powerful output with the added benefit of high efficiency.
This presents dynamic and crisp sounds with less harmonic distortion.
2-Step Gain Mode for the Perfect Hi-Fi Experience
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.
TERATON ALPHA,
The Essence of A&K Audio Technologies
It would not have been possible to combine the exquisitely designed R-2R DAC with ultra-precision resistors and Class A AMP, which was considered impossible to miniaturize, without the innovative audio technology of TERATON ALPHA. SE300 is an innovative audio player that is applied with current and temperature control of TERATON ALPHA technology and an optimized FPGA design.
TERATON ALPHA, engineered through endless research, is Astell&Kern's unique technology that has been designed to produce audio playback that is as close to the original sound through effective power noise removal, efficient power management and unwavering amplification, and a fully converted audio output interface.
Circuit structures of R2R DAC and Dual A/AB AMP that are applied for the first time in the SE300 is completed with the sound solution of TERATON ALPHA, creating the purest form of sounds and music.
Supporting Optimized FPGA OS / NOS Modes
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.
In NOS mode, the player reproduces the pure original sound without any digital processing, allowing users to enjoy the true unprocessed
sounds decoded by the R-2R DAC itself.
OS mode offers partial digital processing that expands the bandwidth of the original signal to offer impressive details, with an expansive
sense of space creating crisp and clear sounds.
New Experience, New User Interface
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.
Immerse yourself in music with the new UI/UX.

DESIGN
The design concept for the A&futura SE300 is 'Stream'.
Like small ripples on water turning into crashing waves, we designed the SE300 with Class A AMP, the ultimate AMP form, to have a unique identity.
The main body made from aluminum has streamlined surfaces that represent the flow of music. Through this, we create a firm yet flexible image. We added intensity by using contrasting materials such as stainless steel and glass to further enhance the theme of 'Stream'. In addition to this, the bottom section of the device curves outward, allowing for a more ergonomic grip whilst using the player.
The right side of the SE300 is coated with stainless steel to enhance visual focus. The polished side and triangular-patterned volume wheel are key to creating powerful and visually striking contrasts. The straight pattern on the rear of the volume wheel elevates the visual density and allows users to control volume and visually check the changes. The wheel lighting is placed behind the volume wheel to avoid direct exposure whilst allowing the light to be reflected on the side decorations and volume wheel knurl, creating the effect of light bursting from the inside.
The rear glass also features a new etching pattern, continuing the concept of 'Stream' The basic pattern features the A logo of Astell&Kern, designed to present an overall flow of stream with differences in size. This etching pattern amplifies the sense of flow with the differences in inclinations, adding a sense of depth to the rectangular rear glass that may otherwise look dull.
