Engineered to Powerful Perfection
The AStell&Kern 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 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.
