Introducing the Astell&Kern KANN CUBE, which achieves more powerful output and lower noise. It 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. To provide a natural and neutral audio experience with minimal distortion, a newly designed OP Amp and Volume IC manages power optimally and efficiently.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.The ESS SABRE PRO series of Digital-to-Analog Converters (DAC) is targeted for premium audiophile and professional recording studio equipment. The SABRE PRO series sets a new benchmark in high-end audio by offering the industry’s highest dynamic range (DNR) with impressively low levels of total harmonic distortion plus noise (THD+N) in a 32-bit, 8-channel DAC. All PRO SABRE DACs feature ESS’s patented 32-bit HyperStream DAC technology which delivers outstanding sound quality and industry leading performance.ESS has two major lines of DAC chips – the ‘SABER PRO’ for audiophile systems and ‘SABER HIFI’ for mobile devices. The SABER PRO DACs are seldomly used for DAPs and are primarily used with Pro-Audio systems or traditional Hi-Fi products. The ES9038PRO is the latest DAC from ESS and the SABER PRO line. KANN CUBE is the first DAP device to adopt the SABER PRO DACs in a dual DAC configuration, dedicating 8-channels for the left and 8-channels for the right side.KANN CUBE offers a 5-pin mini XLR connector for the first time in an Astell&Kern player. Thanks to the even lower noise floor and higher audio output through the XLR connection, you can enjoy pure, clear audio playback. It offers easier connection to your home audio systems and active speakers with balanced connections.
