Due to being a video player as well as Hi-Res Audio unit, the 4" screen natively plays 4k video with a resolution of 1000ppi. Due to extensive development in extending battery life plus the power efficiencies of the new ESS Technology SABRE ES9038PRO chipset, the Astell&Kern AK400 has a battery life of 23 hours per charge at 32-bit/384kHz and 80 hours of low resolution lossy MP3. Headphone amplifier output is 500mW at 1.5 Ohms. Frequency response is from 1Hz to 96kHz, DNR and SNR is 127dB, and channel separation is 132dB due in part to the extensive use of copper shielding between circuit boards. An early production version will be showcased at the upcoming
AXPONA 2106 show in Chicago, with shipping expected to begin June 1.
