KANN

One player to rule them all - KANN.

Astell&Kern;'s KANN provides a new power standard for mobile music performance. Combining a high-quality audio player and a high-performance amplifier, KANN draws on the technological expertise of Astell&Kern;, the leading Portable Hi-Fi Audio manufacturer.

Focusing on a strong output and crystal-clear sound, this is the latest model from Astell&Kern;: the all-in-one KANN
Features
Truly powerful, high-quality output
Astell&Kern; has introduced a new product design that cleverly incorporates a high-performance amplifier into a player for a perfect merger of two independent devices. Supporting the output of 7Vrms when connected via high-gain balanced output, the KANN not only drives high-impedance headphones without an additional amplifier, but also reliably reproduces high-quality sound with low-impedance speakers.
Output optimized to user's listening environment
KANN, the first Astell&Kern; product, is equipped with a line-out circuit designed to set the output values in 4 levels, depending on the user's listening preference; a significant step up from previous products, which did not provide output/volume control. With the selectable output function, you can fine-tune your sound to suit a home system, car audio, or any other listening environment. KANN also supports Astell&Kern;'s 2.5-mm 4-pole balanced outputs (2 Vrms). Unlike the unbalanced type, balanced output removes noise (common mode noise) from "signal + inverting amplifier signal" and has the strength to increase output with its double transmitting signals.
Deliver the perfect original sound
KANN offers the optimal condition to deliver perfect original sound. KANN is capable of bit-to-bit playback up to 32bit 384kHz and native DSD playback up to 11.2MHz, delivering detailed, distortion-free sound just as the artist intended.
Scalability using USB Audio
To increase flexibility of use, you can connect additional USB Audio to KANN via the micro USB port. KANN allows output conversion according to the specifications of the external USB Audio that supports DoP (DSD over PCM) or PCM, and provides continuous music playback with charging via the Type-C USB port while connected to the external USB Audio.
The finest sound quality from audio files stored on a PC
Supporting the bit-to-bit playback up to 32-bit 384kHz when connected to the PC for use as a USB DAC, the KANN produces richer sounds with superior spatial effects and resolution that go far beyond the limits of any PC sound card.
Connecting to a Wireless Network
KANN supports wireless networking DLNA (Ver. 1.0), which makes it easy to work with PC/NAS on the same AP network and through the AK Connect app supporting smartphone/tablet computer interfaces.
Dual memory card slots
KANN has an internal memory of 64GB, but this can be easily and flexibly boosted via the unit's dual memory card slots. KANN supports both standard SD cards and micro SD cards, so users can select their preferred memory type. The memory is expandable up to 832 GB to easily handle larger audio files.
Fast charging
Enjoy up to 6.5 hours of your favorite music with a single 1 hour charge through the fast charger. There is no fear of a dead battery when on a long journey as the 6,200mA large capacity battery offers 15 hours of continuous playback.
