Extreme POWER, KANN CUBE
KANN CUBE is the second model from the KANN line, which focuses on high fidelity with powerful output and low noise. This player is designed to offer a very low noise floor, even with its massive power output.

Introducing the Astell&Kern KANN CUBE, which achieves more powerful output and lower noise.
 
High performance, low-noise amp makes KANN Cube an Absolute Audio Powerhouse
Dual ES9038PRO DACs, the current flagship SABRE DAC chips from ESS designed for Pro Audio Equipment
5-pin Mini XLR output for even less noise
32bit/384kHz, Native DSD256 support
 
The Absolute Audio Powerhouse
KANN CUBE offers 3 different power output options of High / Mid / Low, which can drive any headphone with unprecedented power never seen before in any portable device - 12Vrms for Balanced output and 6Vrms for Unbalanced output.

To provide a natural and neutral audio experience with minimal distortion, a newly designed OP Amp and Volume IC manages power optimally and efficiently.
 
ESS ES9038PRO SABRE Dual DAC
KANN CUBE uses two 8-channel DACs, the ES9038PRO, one for the left and one for the right channel. As each DAC chip sends out 8 channels of audio signal through the Astell&Kern Analog AMP Block, you experience unlimited sound stage and the full depth of the original performance.
