Astell&Kern KANN Max | Powerhouse Digital Audio Player

Improved Power, Sound, and Usability Synergize in A&K’s KANN Max Digital Audio Player

• Powerhouse DAP with 15Vrms of output power
• Quad ESS ES9038Q2M DACs
• Aluminum body, 4.1” 720 x 1280 touch screen, SE 3.5mm and Balanced 2.5mm + 4.4mm outputs
• Improves on the form factor, power, sound, and usability of previous generation KANN players

Ultra-high Output in a Smaller Footprint

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, previously only possible with a stationary headphone amplifier.

KANN Series Player Comparison

Perfect Circuit Design

KANN MAX is equipped with ultra-high output and does not allow any noise delivering the original sound without compromise as it should be. It applies an analog volume controller to deliver a rich dynamic range without loss. By separately configuring the power supply IC for each Audio Block, each IC is stably supplied its required power. Through this design, the interference ripple noise (amplified noise) of the DC-DC power supply is minimized.

Quad-DAC Overwhelming Sound

KANN MAX is the first player in the KANN series to be equipped with 4 ES9038Q2M DACs for high-output performance. By applying Quad DACs, one can be fully allocated to one channel, allowing full expression of sound depth and realism. Combined with A&K’s amp circuit technology and the DAC’s perfect decoding ability, music output is expressed purely without distortion.

BT Sink

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.

ReplayGain Volume Control

Enjoy your own playlists seamlessly through the ReplayGain feature, the ability to adjust sound sources with different volumes to an identical level.

*ReplayGain supports up to 24-bit/192kHz sound sources.

AK File Drop

Using the new AK File Drop, you can freely transfer files wirelessly through a PC, smartphone, or FTP program located on the same network.

LED Head’s Up

KANN MAX features a LED volume wheel which indicates playback volume level and current track bit-rate.
