Design Concept

The design of A&futura SE100 resembles "unrestricted balance" from a composition of a trapezoid and curves together. The volume knob at the end of the side curve is easy to operate from front and back and its shape fits just right in either hand.

The glass back plate has a unique arrangement of "A" logos in a diamond pattern that visualizes the amplification of Astell&Kern before your eyes. As you rotate the device under light its hidden beauty shines.

Premium Value You Can Feel in Your Hands

A&futura SE100 shows our dedication to provide both premium quality and value to our listeners including an eye-catching design. It features a 5-inch touchscreen, Octa-core CPU, and the best audio performance in its league. Astell&Kern is committed to delivering the original performance as the artist intended you to hear and the SE100 is a symbolic example of this vision and effort.

A&futura SE100 introduces an 8-channel DAC chip. 8-channel DACs have previously only been available for premium home audio systems, pro-audio workstations, and recording studio equipment. It is making a debut for the first time in an Astell&Kern portable system.

Your favorite tunes will now sound fundamentality different with even greater dynamic range and refined sound. There are many audio companies that talk about 'technologies', yet Astell&Kern is the only brand that talks about 'progress' in the audio experience.

- The ESS SABRE PRO series of Digital-to-Analog Converters (DAC) is targeted at premium audiophile and recording studio equipment. The SABRE PRO series sets a new benchmark in high-end audio by offering the industry's highest dynamic range (DNR) with impressively low levels of total harmonic distortion plus noise (THD+N) in a 32-bit, 8-channel DAC. All PRO SABRE DACs feature ESS's patented 32-bit HyperStream DAC technology which delivers outstanding sound quality and industry leading performance.

Maximum Output

It is common knowledge in the audio industry that the amplifier plays a critical role in Hi-Fi audio systems. The latest know-how and amplifier design technologies developed by Astell&Kern have brought 4.1Vrms of balanced output power with minimal noise. As the output power increases, the noise fluctuates louder as well. However, A&futura SE100 shows 123dB of SNR (Signal to Noise Ratio) at 4.1Vrms of audio output. At the same time, the noise level on single-ended is even smaller, it produces 122dB of SNR. Pure sound is the result in our technical achievement allowing for powerful, yet clean sound to be delivered gracefully by the SE100.

* SNR (Signal to Noise Ratio) As the signal-to-noise ratio increases, the clearer the sound becomes.
* THD+N (THD + Noise, Distortion) over the THD + Noise signal rate, less distortion is heard.

Femto-Second Clock for Exact Sonic Reproduction

An enhanced voltage-controlled crystal oscillator (VCXO) high-precision clock has been utilized in the A&futura SE100. The reference jitter of Astell&Kern's implementation has improved performance to 800fs (femto seconds), meaning that the SE100 faithfully reproduces your music by precisely measuring and accurately timing the synchronization of all instruments, vocal and even ambience sound recorded in your digital music file together.

Great Performance for the Ultimate Experience

The A&futura SE100 is equipped with an octa-core CPU which allows the player to produce the exact musical detail present in the original recording without distortion and provides a quick, lag-free operation.

The A&futura SE100 features faster booting times, speedy file transfers, lag-free processing and a new intuitive user interface for the ultimate player experience.

Ultimate Sound Quality

The A&futura SE100 supports native bit-to-bit DSD playback up to 11.2MHz for the best sound possible. The music is played back, bit-for-bit, just as the artist and engineer intended for it to be heard.

Faster Charging, Quicker File Transfer

Next generation USB Type-C support allows file transfer speeds up to 10Gbps and supports both data transfer and charging from the same cable.

USB 3.0 protocol transfers data twice as fast when compared to other Astell&Kern players. Charging with a fast charger (at 9V/1.67A) takes only two hours and allows up to 11 hours of continuous playback.

* The maximum 11-hour continuous play is based on 16-bit/44 kHz, FLAC file format, screen off, 75 of volume playback.
* Fast charger (9V/1.67A) and general Charger (5V/2A) are not included in the package.
