Astell&Kern A&futura SE300 Hi-Res Audio Player - Platinum Silver
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 unrivalled components, it offers the true sound philosophy and technology of Astell&Kern.
Immerse yourself into the true analogue sound that the SE300 produces with Class-A AMP and R-2R DAC technologies, for the first time in an Astell&Kern player.
The design concept for the A&futura SE300 is 'Stream'.
Like small ripples on water turning into crashing waves, the SE300 was designed with Class A AMP, the ultimate AMP form, to have a unique identity.
The main body made from aluminium has streamlined surfaces that represent the flow of music. Through this, Astell&Kern has created a firm yet flexible image. Adding intensity by using contrasting materials such as stainless steel and glass to further enhance the theme of 'Stream'. In addition to this, the bottom section of the device curves outward, allowing for a more ergonomic grip whilst using the player.
The right side of the SE300 is coated with stainless steel to enhance visual focus. The polished side and triangular-patterned volume wheel are key to creating powerful and visually striking contrasts. The straight pattern on the rear of the volume wheel elevates the visual density and allows users to control volume and visually check the changes. The wheel lighting is placed behind the volume wheel to avoid direct exposure whilst allowing the light to be reflected on the side decorations and volume wheel knurl, creating the effect of light bursting from the inside.
The rear glass also features a new etching pattern, continuing the concept of 'Stream' The basic pattern features the A logo of Astell&Kern, designed to present an overall flow of stream with differences in size. This etching pattern amplifies the sense of flow with the differences in inclinations, adding a sense of depth to the rectangular rear glass that may otherwise look dull.

ReplayGain Automatically and Uniformly Adjusts Playback Volume
- ReplayGain, which adjusts sound sources with different volumes to an identical level, has been incorporated. Now, enjoy your own playlists seamlessly through the ReplayGain feature on SE300.* ReplayGain supports up to 24-bit/192 kHz sound sources.
AK File Drop to enjoy wireless transfers
- The new AK File Drop function in the SE300 makes file transfers easier and more convenient. Using AK File Drop, you can freely transfer files wirelessly through a PC, smartphone, or FTP program located on the same network. Music file management is now possible with a cableless, wireless solution.
Wireless Hi-Fi Sound Through BT Sink
- BT Sink function connects the SE300 to an external device via Bluetooth, similar to connecting a smartphone with a BT speaker. Music from an external device, such as a smartphone can now be played back in high quality on the SE300 using the BT Sink function.
