The MOON 650D combines a high performance DAC with the versatility of a CD Transport, which use a proprietary CD drive system mounted on our M-Quattro gel-based 4-point floating suspension.

Like two products in one: CD Player + 32-bit DAC
Proprietary CD drive system mounted on our MQuattro gel-based 4-point floating suspension for vibration damping plus true 32-bit asynchronous Digital-to-Analog converter.

MQA pass-through
The MOON 650D features “MQA pass-through” capability. The MQA encoded data on the disc will be outputted on the digital output such that an MQA certified DAC will decode it and give you the full performance that MQA offers.
