Astell&Kern A&futura Series SE100 Player

Boasting the ability to play bit-to-bit DSD playback, the Astell&Kern A&futura Series SE100 is a portable audio player for audiophiles and hi-fi enthusiasts. Utilizing an ESS SABRE ES9038PRO DAC, the player provides low harmonic distortion, high dynamic range, and bit-to-bit playback over an 8-channel DAC.


Listen to multiple formats, including WAV, OGG, APE, and yes, DSD (DSDnative, DSD128, and DSD256). Look at the 5" touchscreen while doing so—it provides a resolution of 720 x 1280, the better to promote its intuitive user experience.

Speedy transfer and lag-free operation is made possible by the octa-core CPU, which also allows for fast booting times and a detailed sonic reproduction of your music files. Hear music through the 3.5mm unbalanced phone jack, or the balanced 4-pole 2.5mm jack, which provides an even more pristine experience. If battery performance is important to you, you'll be pleased by the SE100's ability to play for 11 hours at a time off a two hour fast-charge—though the fast-charger is available separately, and thankfully, the unit boasts a USB 3.0 port. This allows you to transfer data from your machine while charging all the while.

The SABRE PRO series offers high dynamic range (DNR) with impressively low levels of total harmonic distortion plus noise (THD+N) in a 32-bit, 8-channel DAC. All SABRE PRO DACs feature ESS's patented 32-bit HyperStream DAC technology, which delivers professional-level sound quality and performance.

The SE100 sports 4.1 Vrms of balanced output power with 123 dB of SNR (signal to noise ratio). At the same time, the noise level on single-ended cable is even lower, producing 122 dB of SNR.

A voltage-controlled crystal oscillator (VCXO) high-precision clock has been utilized to bring a performance of 800 femtoseconds. The A&futura SE100 is equipped with an octa-core CPU. This allows the player to produce the exact musical detail present in the original recording without distortion and provides quick, lag-free operation. The machine sports faster booting times, speedy file transfers, lag-free processing, and an intuitive user interface. The A&futura SE100 supports native bit-to-bit DSD playback up to 11.2 MHz. The music is played back bit-for-bit, just as the artist and engineer intended for it to be heard.
