Equipped with trailblazing audio technology developed in-house and uncompromising craftsmanship, the fourth model in the A&futura range reproduces an entirely new, natural yet dynamic sound.
Harnessing decades of audio research and development, the A&Futura SE300 expands the scope of analogue sound with entirely new audio technology. A&Futura SE300 is built with an ultra-refined R-2R DAC, instead of a Delta-Sigma DAC which is most commonly used in audio players. R-2R DAC, also known as Ladder DAC as it arranges resistors in a ladder form, offers a natural Hi-Fi sound with unrivalled dynamism.
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, arranges resistors in a ladder form and 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 of development and a lot of trial and error, we have managed to overcome this and create a new analogue sound. In the process, we meticulously selected each one of the 96 ultra-precision resistors and finalized our R-2R DAC technology.
It is key to total the accurate current value with resistors that have the smallest error ranges to create Hi-Fi sound with an R-2R DAC. To realize this, Astell&Kern inspected each specifically selected ultra-precision resistor with a 0.01% error range to complete the design of SE300.
The SE300 comes with a Dual AMP mode. Class A amplification creates low distortions and natural sounds and a Class AB amplification plays dynamic sounds with high efficiency so users can pick and choose from the two amps according to their listening preferences and the genre of music that they are playing.
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.
For seamless use of sensitive IEMs and hard-to-drive headphones, a device must provide suitable output, respective to the connected device’s specification.
The SE300 supports a 2-step Gain Level mode to create the perfect 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.
