DAC Chip
You may not even realise it, but most of us use a digital-to-analogue converter (commonly known as a DAC) daily. Built into your computers, tablets and smartphones, a DAC is fundamental to unlocking the convenience of digital music. Any device that acts as a digital sound source will need a DAC to convert digital audio to analog. A DAC converts the digital information stored in “0s and 1s” into an analog signal that's passed to speakers or headphones and ultimately our ear. In short, DACs play a large part in making digital music hearable. 

While this technical process is undoubtedly impressive, the DAC embedded into your smartphones or laptops is nowhere good enough to listen to your favourite music recordings in high quality. So, if you want to listen to music in high quality, an external DAC is essential to allow headphones or speakers to perform at their potential. An external DAC, first and foremost, will improve audio quality dramatically.

A&futura is a product line from Astell&Kern that exemplifies the company's never-ending pursuit of innovation. The SE300, the fourth model in the A&futura line, is a high-end Digital Audio Player that builds on this identity and broadens the sound's range with a completely new applied technology. The A&futura SE300 features an incredibly refined R-2R DAC, Class A/AB dual amps created with Astell&Kern's exclusive TERATON ALPHA technology, and for the first time, a self-created FPGA optimised technology. It offers the true sound philosophy and technology of Astell&Kern with these unmatched components. As for the headphone outputs it has 3.5mm, 2.5mm & 4.4mm outputs covering a range of use cases. Experience the first "true" analogue sound produced by an Astell&Kern player, the SE300, using Class-A/AB AMP and R-2R DAC technologies.

Instead of the Delta-Sigma DAC that is most frequently found in other audio players, the SE300 has an R-2R DAC. R-2R DAC, also known as Ladder DAC because resistors are arranged in a ladder form, provides natural yet dynamic Hi-Fi sounds, but it is very technical and challenging to implement because it calls for intricately crafted resistor units and is challenging to manage current controls. The 96 ultra-precision resistors were carefully chosen by a team of engineers as they finalised the R-2R DAC technology in SE300. You can now achieve analogue sound from a digital source thanks to Astell&Kern's SE300, the result of their exhaustive search for the ideal audio solution. With Astell&Kern's unmatched audio technology, the SE300 supports DSD256 and up to 32bit/384kHz, enabling you to enjoy your favourite music wherever you are.

True Hi-Fi 24-bit decoding is made possible by the R-2R DAC embedded inside the SE300, which arranges 48 pairs (23xR and 25x2R) of 96 ultra-precision resistors to produce analogue signals. To present the Hi-Fi sound with an R-2R DAC, it is essential to add the precise current value with resistors with the tiniest error ranges. To achieve this, Astell&Kern examined each individually chosen ultra-precision resistor with an error range of 0.01% to finish designing the SE300. To create Hi-Fi sound without distortions within such an extreme precision design, a team of engineers at Astell&Kern analysed and preconceived any potential impacts that may be caused by changes in temperature. The SE300 comes with TCR10 specifications to minimise the changes in the 0.01% resistor error range.

The Dual AMP mode is included with the SE300. You can choose between the two amplifiers based on your listening preferences and the type of music you prefer because Class A amplification produces low distortion and natural sounds, and Class AB amplification plays dynamic sounds with high efficiency. This design improves output and eliminates noise while consuming less power. The best linear audio output is provided by a Class A AMP, an analogue amplifier that produces smooth, warm, and natural tones by amplifying signals without distortion or signal loss. Through the natural and potent Class A AMP, the refined analogue signal created by the R-2R DAC reproduces a sound that is most similar to the original analogue audio. An analogue amp known as a class AB amp provides a potent output in addition to having high efficiency. Less harmonic distortion is presented with dynamic and crisp sounds.

The SE300 can perfectly match a wide range of headphones and IEMs, while still producing high-quality audio with its 2-step Gain Level mode. The two-step gain setting with the "Normal" and "High Gain" modes can produce a high current output with a powerful sound and excellent driver control. It has never been simpler to drive high-impedance headphones with up to 6 Vrms from the balanced connections.

The SE300 features an FPGA that Astell&Kern exclusively developed and offers OS/NOS modes that are optimised. Instead of using standard off-the-shelf commercial semiconductor chipsets, the SE300 relays digital signals to the R-2R DAC through its algorithm using an FPGA (Field Programmable Gate Array) that a team of engineers at Astell&Kern self-developed for optimised design. The SE300-specific FPGA from Astell&Kern supports the ideal OS (Over Sampling) / NOS (Non-Over Sampling). Enjoy the carefully crafted sound styles that NOS and OS modes faithfully reproduce for the SE300's hardware and programs.

NOTE: 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, offering impressive details with an expansive sense of space and creating crisp and clear sounds.
