Astell&Kern
KANN MAX // Portable High-Resolution Audio Player
Product Description
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 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.
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. Despite its compact size, all power-related components have been analyzed and the power circuit has been redesigned several times to achieve 13 hours of continuous playback.
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.
KANN MAX is the first player in the KANN series to be equipped with four ES9038Q2M DACs for high-output performance. By applying Quad DACs, one DAC can be fully allocated to one channel, so the depth and realism of the sound source can be expressed to the fullest. Combined with Astell&Kern's amplifier circuit technology that naturally and delicately raises the strengths of the DAC, and the perfect decoding ability of the DAC to deliver the original sound as it is, music output is expressed as the original sound without distortion.
TERATON ALPHA is AK's ultimate Sound Solution to produce audio playback that is close to the original sound through the audio output interface by use of effective power noise removal, efficient power management and amplification with minimal distortion.
The latest Bluetooth version provides high sound quality with the convenience of wireless playback to headphones and IEMs. Bluetooth 5.0 features faster transmission speed, greater range and a more stable wireless connection when compared to Bluetooth 4.2. Both LDAC and aptX HD are support to provide audiophiles with the best wireless sound possible. 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 using the BT Sink function.
