KANN MAX Product Intro Video
KANN MAX Product Intro Video
The KANN series is a portable player lineup loved by audiophiles all over the world for its performance focused on high output and clear sound. KANN MAX, the fourth product in the KANN series, builds on the advantages of the KANN series with higher output and portability. It provides 4 levels of gain and up to 15Vrms output so that a wide array of headphones can be driven in an optimal state. By integrating the proven design of KANN series into a lighter weight and smaller sized player, A&K realized both ultra-high output and low noise. KANN MAX features ESS ES9038Q2M Quad-DAC together with Astell&Kern's unique audio technology to provide the best performance you can feel from a portable DAP.
KANN MAX takes the identity of the series to the next level to provide a perfect experience with high power and clear sound. It provides 4 stages of gain level and ultra-high output of up to 15Vrms, which was previously only possible with a stationary headphone amplifier. KANN MAX can perfectly drive even the most sophisticated headphones with high impedance. KANN MAX offers a smaller size and weight than the KANN APLHA player, which boasted the best portability in the existing KANN series. Although smaller in size, all power-related components have been analyzed and the power circuit has been redesigned several times to achieve 13 hours of continuous playback.
As the output increases, so does the noise level. KANN MAX is equipped with ultra-high output, does not allow any noise and conveys Astell&Kern's philosophy of delivering the original sound as it should be, without compromise. A&K completed the perfect circuit design to achieve this. KANN MAX applies an analog volume controller to deliver a rich dynamic range without loss. By separately configuring the power supply IC for each Audio Block divided into DAC, Volume, and AMP, KANN MAX is designed to stably supply the power required for each Audio IC. Through this design, the interference ripple noise of the DC-DC power supply (the shaking noise phenomenon that occurs when power is supplied) is removed. Audio noise that can be heard amplified like audio sound in OP AMP is minimized. Ultra-high output and low noise in the KANN MAX was achieved through different circuit design, including creating and dividing a limited PCB that is the same size as KANN ALPHA into 12 layers and reviewing the physical size of the device applied to the AMP circuit.
KANN MAX is the first player in the KANN series to be equipped with four ES9038Q2M DACs for high-output performance. By applying Quad DACs, one DAC can be fully allocated to one channel, so the depth and realism of the sound source can be expressed to the fullest. Combined with Astell&Kern's amplifier circuit technology that naturally and delicately raises the strengths of the DAC, and the perfect decoding ability of the DAC to deliver the original sound as it is, music output is expressed as the original sound without distortion. Four DACs applied to KANN MAX, a power supply IC configured for each audio block, and a perfect circuit design produce ultra-high output and low noise, providing you with the best performance and sound that the KANN series is known for.
In order to minimize contact noise from the output jacks, a gold PVD coating methods is applied to the headphone connector instead of the typical rings used by other products. This improves both design and function.
Bit-to-bit playback is available up to 32-bit/768Hz, and DSD playback is native up to 22.4MHz, for uncompressed sound quality, staying true to the artist’s original intention, in high-resolution and with minimal distortion.
TERATON ALPHA is AK's ultimate Sound Solution to produce audio playback that is close to the original sound through the audio output interface by use of effective power noise removal, efficient power management and amplification with minimal distortion. TERATON ALPHA features Astell&Kern's patented technologies, which are the result of tens of thousands of hours of continuous research and development to produce sound close to the original sound the artist and producer intended.
The latest Bluetooth version provides high sound quality with the convenience of wireless playback to headphones and IEMs. Bluetooth 5.0 features faster transmission speed, greater range and a more stable wireless connection when compared to Bluetooth 4.2. Both LDAC and aptX HD are support to provide audiophiles with the best wireless sound possible.
The newly introduced BT Sink function connects the KANN MAX to an external device via Bluetooth, similar to connecting a smartphone with a BT speaker. Music from an external device, such as a smartphone can now be played back in high-quality on the KANN MAX using the BT Sink function.
ReplayGain, which adjusts sound sources with different volumes to an identical level, has been applied. Now, enjoy your own playlists seamlessly through the ReplayGain feature on KANN MAX.
*ReplayGain supports up to 24-bit/192kHz sound sources.
The new AK File Drop function in the KANN MAX makes files transfers easier and more convenient. Using AK File Drop, you can freely transfer files wirelessly through a PC, smartphone, or FTP program located on the same network. Music file management is now possible with a cableless, wireless solution.
KANN MAX features a LED volume wheel which displays various playback information, including volume level and bit-rate of the track currently playing.
*LED can be turned on or off according to user setting.
MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. Visit mqa.co.uk for more information. Astell&Kern KANN MAX includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording.

KANN MAX has been visualized as Maximum while inheriting the bold concept of the KANN series to capture the overflowing horsepower of a high-performance sports car and the intense power of a rocket engine. While the existing KANN series image was a heavy and strong image like an off-road car, with KANN MAX, A&K wanted to continue the identity of the Astell&Kern KANN lineup while boasting a thinner size and high-power performance like a high-performance sports car. The slimmer shape is emphasized with the hexagonal top line that narrows sharply from the bottom up, and the hairline treatment on the back expresses the sense of speed and shows confidence that it can produce powerful output. The wheel protectors wrapped around the volume wheel radiate sparks in the shape of a powerful engine mounted on them, giving off a strong image that looks like it will pop out at any moment.
