Astell&Kern KANN MAX Portable Music Player

Engineered to Powerful Perfection

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 KANNseries, 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 the KANN series into a lighter weight and smaller sized player, we have 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.

Ultra-High Output in a Smaller Size Device

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.

Perfect Circuit Design That Achieves Both Ultra-High Output and Low Noise

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. Together, we have 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.
