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.
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.
