Astell & Kern KANN Portable Audio Player

The KANN Portable High-Definition Portable Sound System from Astell & Kern is a pocket-sized audio system capable of ultra-high-resolution audio playback. The device delivers distortion-free sound without data loss by operating at 32-bit/384 kHz, as well as native DSD playback up to DSD256 (1-bit/11.2 MHz). Featuring an integrated single-channel KM AK4490 DAC with balanced outputs to guarantee fantastic quality.

The KANN can be used as an external DAC when connecting via USB to a computer. As well as the great DAC built in, the KANN has a high powered amplifier which is capable of driving both high-impedance but can also drive low impedance speakers at a high-quality. 

The 4.0" touchscreen provides smartphone-style control over playback, while the brushed aluminium body and volume wheel provide a smooth analogue feel. The built-in battery recharges via USB 3.0 and lasts for up to 15 hours of playback. Additionally, the unit offers a "fast charger" function, which provides up to 6.5 hours of playback time with a single hour charge. The KANN ships with a USB Type-C cable, two SD card slot covers, two microSD card slot covers, and two protective films to protect the front screen.
