We have done some analysis with MQA-CD-files with Roon in our NADAC+PLAYER and documented this in an Excel-File. Here you can see some extracts in the following screenshots:
The necessary algorithms for MQA-Authentication seems to be highly complex and error-prone, so the fixing by Roonlabs seems to be expensive.
