Astell and Kern are keeping their SE180 model strong with a new attachment that is sure to significantly upgrade your experience. Their latest SEM4 module 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 SEM modules. With the introduction of digital audio remaster (DAR) technology you will be able to enjoy even more vivid, original sound.
DARtechnology is developed to upsample the sample rate of the sound source being played to go beyond the limits of the source format. The high sample rate allows more refined play and offers delicate and analog-like original sound, helping you to enjoy the richness of the original sound, subtle differences in the nuance of the music, and rich sounds at a higher level. Max PCM rate 384kHz/DSD256 conversion play is supported, and the files will be converted to and played in the sample rates that fit the source sound.
The SEM4 also features Astell&Kern’s new generation AMP technology. The complete physical separation of the system unit and the DAC module perfectly prevents noise from the power and RF noises from the system unit, meaning no noise will interrupt your music.
Lastly, the SEM4 comes loaded with A&K’s Tetron Alpha sound solution, which aims to get as close as possible to the original sound through effective power noise removal, efficient power consumption, unwavering amplification, and a perfectly converted audio output interface.
The SEM4 is slated to release on May 12th for $399. It is currently available for pre-order on their website here.
