Astell&Kern A&Futura SE300 Titan, Digital Audio Player: High-Resolution R2R Music Player DAP (SE300 Titan)
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.

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.
