Roon does not decode MQA currently and it is on the list of features for some future date. Roon do not give times for these things to be delivered as failure to comply for whatever reason leads to disappointment.
This is how I understand things. We are all patiently awaiting this.
Tidal Masters on a Laptop will decodefor you.
Roon Labs is the latest software partner to announce integrated MQA support for its award-winning music player. Roon’s desktop software will support local MQA file playback, as well as TIDAL MQA streaming for HiFi subscribers.
Well, I have a Bluesound Node 2 (which supports MQA) and just bought Roon. Very disappointed to see that Roon + Node2 => no MQA… Apologies if this is user error, but I get only 44.1 or 48 kHz out of the Node2 coax out when streaming MQA flac through Roon (with digital processing disabled of course).
