SEM3 is an Interchangeable All-in-One module for the SE180. It shapes the sound with the ESS ES9038Q2M Quad DAC, with two DACs per channel for dedicated decoding. This gives a more detailed and balanced sound with great depth and spatial realism. The SEM3 supports up to 32bit / 768kHz / Native DSD512.
The next generation AMP technology is also applied in the SEM3 all-in-one module. From the selection of OP-AMP parts, to circuit design, board layout and tuning, everything has been completely redesigned to produce the best sound.
By physically separating the main body from the All-in-One module, we completely block power and RF noise that may occur from the main body. This creates an independent structure that prevents noise from interfering with music playback. Balanced and unbalanced signals are separated for each channel to provide the best possible sound through independent circuit design without interference.
TERATON ALPHA is AK's ultimate Sound Solution to produce audio playback that is close to the original sound through the audio output interface by use of effective power noise removal, efficient power management and amplification with minimal distortion. It features Astell&Kern's patented technologies, which are the result of tens of thousands of hours of continuous research and development to produce sound close to the original sound the artist and producer intended.
