Pioneer and Onkyo have announced a new firmware update for the Pioneer XDP-30R and Onkyo DP-S1 Digital Audio Players that enables them to play downloaded MQA music. MQA, short for Master Quality Authenticated, is a new hi-res audio codec that delivers the inherent quality of master studio recordings but in file sizes that are a fraction of that taken up by traditional hi-res formats. The enabling of MQA playback delivers on a promise that was made at the launch of the players earlier in the summer of 2017.
