The Future of Analog Sound, SE300
A&futura from Astell&Kern is a product line that represents Astell&Kern’s ceaseless efforts for innovation. SE300, the fourth model in the A&futura range is a premium digital audio player that inherits this identity and expands the scope of sound with an entirely new implemented technology.

A&futura SE300 is equipped with an ultra-refined R-2R DAC, Class A/AB dual amps born with our proprietary TERATON ALPHA technology, and for the first time a self-developed FPGA optimized technology. With these unrivaled components, it offers the true sound philosophy and technology of Astell&Kern.

Immerse yourself into the true analog sound that the SE300 produces with Class-A AMP and R-2R DAC technologies, for the first time in an Astell&Kern player.

Innovative Materials Inspired by Astell&Kern’s craftsmanship
Constructed using Grade 5 Titanium alloy, the SE300 Titan Limited Edition is designed to increase both the internal corrosive resistance and strength inherent in pure titanium. Titanium Grade 5, an alloy blend of aluminum and vanadium, embodies exceptional strength while retaining a light weight.

Recognized for its increased resistance to corrosion and absence of toxicity unlike aluminum, this alloy is the material of choice in aerospace, medical, and a wide range of other applications. Its ability to withstand heat and electrical conductivity also positions it as an optimal substance for reducing temperature variations and electrical interference within R-2R DACs and analog amplifiers.

Despite these numerous advantages, the material's intricate processing is attributed to its formidable strength and limited thermal conductivity.

As a result, its integration into the product relies exclusively on the finesse of ultra-precision manufacturing methods. Astell&Kern approaches this by taking on the challenge: The front cover, initially shaped with precision, undergoes meticulous processing with dedicated polishing equipment, while the side sections, adorned with wave-like patterns, are meticulously crafted to achieve a consistent surface texture. This was perfected by a combination of 6-axis control robots and the skilled hands of engineers, resulting in a flawless surface.

The wheel and side keys, undergo meticulous refinement through a Swiss-made 5-axis vibration-free CNC machine, a technique often employed in crafting premium wristwatches. The utilization of an AF coating further ensures the enduring allure and tactile experience of the Titan Edition.

Discover the SE300 Titan Limited Edition and embrace the cutting-edge analog sound experience from Astell&Kern right at your fingertips. The limited edition package for the SE300 Titan includes a leather case.

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 DAC
The 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 Sound
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.

Ultra-precision TCR10 Specifications
To 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 mode
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 Mode
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.
