To help match the full depth of original audio recordings, the KANN MAX has been given quad ESS ES9038Q3M DACs. An analog volume controller delivers rich dynamic range without loss. Separate power supplies have been used for each audio block divided into DAC, volume, and amp. Through this design, the interference ripple noise of the DC-DC power supply is removed, thereby minimizing noise that is usually amplified by the op amp. KANN MAX is equipped with Bluetooth 5.0 and support for 24-bit aptX-HD and LDAC codecs. The BT Sink function offers a wealth of flexibility by allowing you to transmit wireless audio from another device or streaming audio from the KANN MAX directly to Bluetooth speakers.
