Astell&Kern SE300 Titan Limited Edition Digital Audio Player

Featuring special materials and precision craftsmanship, the SE300 Titan Limited Edition is a pioneer in material innovation, delivering both a premium feel and unparalleled sound from the R-2R DAC and analog amp.
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 in a new ultra lightweight package.

The future of analog sound.
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.

Fully Discrete 24bit R-2R DAC
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.

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.

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.

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.
