Introduction to MQA

MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. DX5 MQA adopts MOA technology to receive and decode MQA audio and provide master-level sound.
