Limited-Time Astell&Kern Bundle Offer!

Buy the Astell&Kern A&futura SE180 Digital Music Player, and get the interchangeable SEM4 Dual-DAC Module, free-of-charge (while stocks last).

SE180 is also the first player to harbour TERATON ALPHA technology that effectively removes power noise and provides efficient power consumption and amplification right through to the audio output interface stage, which is where the digital-to-analogue signal conversion (DAC) takes place. This is audio technology that Astell&Kern has consistently developed and perfected over the years.

The A&futura SE180 digital audio player allows music fans to customise their sound with different audio-flavoured DAC modules to find the hi-fi-grade sonics that suit.

Following the previous SEM2 and SEM3, the new SEM4 module was born from the key concept of "Shape Your Sound,". SEM4 is equipped with the AK4493SEQ dual DAC, the latest DAC from Asahi Kasei, which minimizes loss and noise interference from the original sound while offering 14 hours of playback performance — the longest among all released SEM modules to date.

SEM4 supports up to 32-bit/768kHz, Native DSD and you will be able to enjoy even more vidid, original sound with the introduction of digital audio remaster (DAR) technology.

The SE180 already comes with the standard SEM1 module installed. This bundle deal allows you to gain the benefits of the latest SEM4 module at no extra charge!
