More than a portable player

Astell&Kern KANN Cube

The KANN Cube is the most powerful portable music player from Astell&Kern to date. It delivers exceptional sound quality from hard-to-drive high-performance headphones. And it can play from a variety of digital music sources.

Play your downloaded high-res FLAC, WAV, and DSD files in their native resolution. You can even stream your favorite music service via Wi-Fi. Built-in Bluetooth lets you listen through wireless headphones. A 5-pin mini XLR jack lets you connect the player to your high-performance audio system without compromising sound quality.

Maximize your headphone listening

The KANN Cube has a standard 3.5mm stereo headphone jack and a 2.5mm balanced 4-pole output for compatible high-performance headphones.

The balanced output delivers up to 12Vrms — the highest output ever for an Astell&Kern portable player. So you don't need a separate headphone amp, even with the most demanding high-performance 'phones.

You can also select high, medium or low output modes to best match the type of headphones you're driving.

Top-flight audio performance

The KANN Cube has two professional-grade eight-channel digital-to-analog converters (DACs). That's eight DAC channels of processing for each stereo audio channel. You'll experience an exceptionally open soundstage with effortless detail.

The KANN Cube can do native playback of Direct Stream Digital (DSD) files — even Quad DSD. You also get bit-perfect playback for PCM-based files up to 32-bit/384kHz.

The player is compatible with MQA, a high-resolution audio format used in TIDAL's "Masters" streaming music service tier and by other music download sites on the web. And it delivers surprisingly detailed sound even from CD-quality and compressed music files.

Astell&Kern Open APP

Astell&Kern's free Open APP service lets you install popular music apps on your player. So you can enjoy high-res streaming with your TIDAL or Qobuz subscriptions. You can also install Deezer, Spotify, Amazon music, Pandora and more. Listen to internet radio stations and podcasts through TuneIn Radio, and even enjoy SiriusXM programs..

Built-in and expandable memory

The KANN Cube features a 128GB internal memory. The microSD card slot can handle cards up to 512GB, for total storage of up to 640GB. The player connects to your computer via an included USB-C cable for speedy file transfers.

More premium features

The player has a generous 5" touchscreen, giving you a clear, high-def view of music selections and menus. A gnarled volume control knob lets you make minute changes. The player has a milled aluminum casing, designed for durability and visual appeal.

Product Research

Features

Overview: The Astell & Kern's KANN CUBE is a powerful, high-end portable digital audio player that offers high performance, low noise, and unique styling. The KANN CUBE features dual 8-channel ESS DACs, with playback of PCM up to 384kHz, Native DSD to DSD256, and MQA files. It has a Wolf Gray aluminum body with a 5" touch display (720 x 1280) for touch control, menu access, and album art. You can connect wirelessly via Bluetooth or Wi-Fi, or load your music files onto the built-in 128 GB memory or a microSD card. The KANN CUBE features balanced and unbalanced headphone outputs, and a 5-pin Mini XLR output. The device charges with the included USB-C charging cable.

Digital-to-Analog Converters: The KANN CUBE uses two ES9038PRO DACs (digital-to-analog converters), one for the left channel and one for the right. The ESS Sabre PRO series of DACs are typically made for Pro Audio systems and traditional Hi-Fi products. They offer the highest dynamic range available, and extremely low THD+N for outstanding audio quality and extremely low noise. The KANN CUBE is the first Digital Audio Player (DAP) to use the Sabre Pro DAC in a dual-DAC configuration, providing 8 channels of audio for the left and 8 for the right side.

Supported Audio Formats: The KANN CUBE is capable of download and playback of high resolution digital music files up to 32-bit/382kHz; including FLAC, WAV, ALAC, AIFF, DFF, and DSF. The device includes MQA (Master Quality Authenticated) technology, allowing you to play back and stream MQA audio files which have the sound of the original master recording. It also supports playback of DSD music files up to 11.2MHz (DSD256). In addition, the KANN CUBE will support highly compressed music files such as MP3, WMA, AAC, OGG, and APE.

Balanced / Unbalanced Outputs: The KANN CUBE is the first Astell & Kern audio player equipped with a 5-pin mini XLR connector. The 5-pin XLR offers a lower noise floor and higher audio output for a clean and pure audio signal. With a 5-pin mini XLR to 3-pin XLR cable, it is easy to connect the player to your home audio system or to a pair of active speakers with a balanced input. The KANN CUBE also has a 2.5mm 4-pole balanced and a standard 3.5mm unbalanced headphone output. The 3.5mm unbalanced output also doubles as a S/PIDF optical mini jack.

Power Output Options: The KANN CUBE's newly designed OP Amp and Volume IC delivers a natural sounding audio signal with little or no distortion. Three different power output options (High, Mid, Low) are available, so you can drive virtually any headphone available:

Output Selection Balanced
2.5mm
Unbalanced
3.5mm
5-pin mini XLR
High 12 Vrms 6 Vrms 4 Vrms
(no output selection)
Mid 8 Vrms 4 Vrms
Low 4 Vrms 2 Vrms

Built-in Memory + External Storage: The KANN CUBE has a built-in 128 GB internal flash memory for downloading and storing your digital music files. You can also insert a microSD card (up to 512 GB) in the memory card slot on the side of the device for additional storage capacity, for a total maximum storage capacity of 640 GB. The memory card should be formatted in FAT32.

Media File Transfer: You can download digital music files from your Windows PC or Mac computer to the Astell & Kern KANN CUBE through its USB-C USB port and the included USB-C to USB cable. The device is compatible with Windows 7, 8, or 10 (32-bit or 64-bit versions of each). It also support Mac OS X 10.7 and up. Mac users need to download and install the MTP program from the Astell & Kern website.

USB DAC: The USB DAC functionality allows the KANN CUBE to be recognized as a sound card on a computer. When the device's USB-C port is connected to a free USB port on your Windows PC or Mac computer, the music from your computer can be played through the KANN CUBE's headphone outputs for an enhanced listening experience. This USB DAC connection bypasses the inferior soundcard of your computer or laptop, providing much higher sound quality.

Femto Clock: The Astell & Kern KANN CUBE uses a voltage-controlled crystal oscillator (VCXO) high-precision clock with a reference jitter value of 250 femtoseconds. Femto clocks are typically used in high-end audio components.

Built-In Wi-Fi: The KANN CUBE features built-in 2.4GHz Wi-Fi (802.11 b/g/n) which allows you to connect to your home's Wi-Fi network wirelessly with support for AK Connect. AK Connect lets you connect with other network-ready Astell & Kern devices and speakers (sold separately). It requires the AK Connect app, which is compatible with Apple iOS 8 or later, and Android OS 4.2 and up.

Bluetooth Transmitter: The KANN CUBE has built-in Bluetooth 4.2 for connecting a Bluetooth speaker, headphone, or receiver so you can listen to your digital music files wirelessly. In addition to support for the standard Bluetooth SBC codec, the KANN CUBE offers support for aptX HD allowing CD quality (16-bit/44.1kHz) wireless audio playback for Bluetooth speakers, headphones, and receivers that also support aptX HD.

Note: DSD playback is not available via Bluetooth, and performance may be limited for high-res playback; 48 kHz or lower resolution is recommended). Car audio Bluetooth connections are not supported.

20-band EQ: The KANN CUBE features a 20-band EQ to allow you to make detailed adjustments in the original sound to suit your tastes. You can set the EQ curve by simply "drawing" the curve on the touchscreen. The EQ frequency bands include: 30Hz, 45Hz, 60Hz, 90Hz, 120Hz, 180Hz, 250Hz, 380Hz, 500Hz, 750Hz, 1kHz, 1.5kHz, 2kHz, 3kHz, 4kHz, 6kHz, 8kHz, 12kHz, 14kHz, and 18kHz. You can adjust the gain from -5dB to +5dB in 0.1dB increments, and the Q from 0.1 to 4.0dB in 0.1dB increments. If you choose not to activate the EQ, you can use the Pro EQ presets recommended by professionals.

On-board Controls: The KANN CUBE has a side-mounted rotary wheel for volume control with values from 0 to 80. There are also five physical buttons on the top, front, and side of the player: Power (top), Home (front), Play/pause (side), Previous/rewind (side), and Next/fast forward (side).

Gapless Playback: Gapless Playback allows you to play the next song without any interruptions or silence. Gapless playback is only supported between two audio files with identical bit rates, sample rates, and channels.

Power Requirements: The KANN CUBE is equipped with a rechargeable Lithium-Polymer battery (7400mAh / 3.8V). Using a commercially-available 9-volt, 1.67A output adapter, the device can fast charge in approximately 4 hours. Normal charging (5V 2A) takes place in approximately 5 hours 30 minutes. A 39" USB-C to USB cable is included to connect the player to your charging device. A fully charged battery can provide up to approximately 9 hours of continuous playback time.
