The astro silver 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).

KANN utilizes an integrated single-channel KM AK4490 DAC and balanced output to provide exceptional sonic quality and detail. It can also be used as an external DAC when connected to a PC via USB. The built-in high-powered amplifier can not only drive high-impedance headphones, but can also reliably reproduce high-quality sound with low-impedance speakers. Additionally, the unit is equipped with a line-out circuit designed to set the output values in four levels, depending on the users listening preference. With the selectable output function, you can fine-tune your sound to suit a home system, car audio, or any other listening environment.

The 4.0" touchscreen provides smartphone-style control over playback, while the brushed aluminum body and volume wheel provide a smooth analog 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.

Powerful, High-Quality Output

  • Astell&Kern has introduced a new product design that cleverly incorporates a high-performance amplifier into a player for an ideal merger of two independent devices
  • Supporting 7 Vrms output 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
    • Normal
      • Unbalance 2 Vrms
      • Balance 2 Vrms (Condition No Load)
    • High
      • Unbalance 4 Vrms
      • Balance 7 Vrms (Condition No Load)

Output Optimized to User's Listening Environment

  • KANN is equipped with a line-out circuit designed to set the output values in 4 levels, depending on the user's listening preference
  • 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 2.5mm 4-pole balanced outputs (2 Vrms), and 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

High Resolution Playback

  • KANN is capable of bit-to-bit playback up to 32-bit 384 kHz and native DSD playback up to 11.2 MHz, 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 per 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
    • USB audio (Digital Out) output is available only when digital input is possible through USB
    • DoP (DSD over PCM): This is a standard for transferring DSD data to USB interface; it sends DSD data by mounting them onto PCM data frames
    • To link KANN with an external USB Audio, an OTG cable (purchased separately) is required
    • The separately purchased cable connecting the OTG cable to an external USB Audio must be appropriate for the specification of the USB Audio

High Quality Sound from Audio Files Stored on a PC

  • Supporting the bit-to-bit playback up to 32-bit 384 kHz 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
    • The KANN supports up to 32-bit 384 kHz with specs of USB Audio Class 2.0
    • 64/128/256 MHz DSD formats can be played back with the USB DAC driver installed

Wireless Network Connections

  • 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.
    • DMP (Digital Media Player): Finds a list of content on a media server for selection and playback
    • DMC (Digital Media Controller): Finds a list of content on a media server and establishes a connection to a playback-capable device (renderer) – by default, a DMC establishes a connection between a media server and media renderer and controls content playback-related operations
    • DMS (Digital Media Server = Network Server): Stores the media content to be shared – when connected to a network, the DMS transmits/distributes the media content for other devices to stream or download
    • DMR (Digital Media Renderer = Network Player): Connects to a media server via media controller for content playback

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 for a total of 832 GB
  • KANN supports both standard SD cards and microSD cards, so users can select their preferred memory type; the memory is expandable up to 768GB to easily handle larger audio files
    • Built-in Memory (64 GB)
    • SD (Max. 512GB)
    • microSD (Max. 256GB)

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 6,200mAh large capacity battery offers 15 hours of continuous playback
    • The maximum 15-hour continuous play is based on 16-bit/44 kHz, FLAC file format, screen off, 50% of volume, and Normal playback
    • Fast charger (9V/1.67A) and general Charger (5V/2A) are not included in the package

Design Concept

  • During assembly, the parts are slid into the aluminum extruded body, and the unique, no-joint design delivers a durable yet sleek appearance
  • The innovative volume wheel makes one-hand control easy – by positioning the main control buttons to the bottom of the front panel, convenient music search and quick home screen operation are intuitive
