Moondrop announced its first USB dongle DAC-AMP the MOONRIVER 2. It is a HiFi portable DAC/AMP featuring dual CS43198 DAC Chips and dual OP-AMP four-channel outputs. The device has a modern and minimalistic look with the digging aluminium structure and CNC precision machining panelled.
The indicator light on the front shows you the audio resource format and gain mode status.
The device is plug-and-play with volume controls of its own.
The MOONRIVER 2 adopts two CS43198 decoder chips, a flagship product from world-renowned audio integrated circuit manufacture Cirrus Logic. That helps this DAC/AMP reach a stunning 131 dB S/N ratio (A-weighted) and support up to DSD256 and 32-bit/384 kHz files. Dual parallel DAC chips provide a four-channel circuit with two high-performance op-amp chips, which keeps the noise floor low and enhances the sound quality further.
