[QUOTE="mr_b, post: 1106365, member: 21859"] OK, correction folks. Just did the litmus test. Volumio 3 appears to be able to do the first software unfold. The Master Quality button shown above does liberate better quality from MQA tracks. First, with Volumio MQ turned off. On this MQA track reflects 44.1khz and 32bit: [ATTACH type="full" alt="Screenshot_20220620-195353_Volumio.jpg"]11331[/ATTACH] DAC shows: [ATTACH type="full" alt="20220620_195547.jpg"]11332[/ATTACH] Then, with MQ button on. Same track 48khz 24bit. So it's doing something: [ATTACH type="full"]11333[/ATTACH] DAC shows: [ATTACH type="full"]11334[/ATTACH] Not sure an increase from 44.1 to 48khz is worth much, but clearly the MQ button does something.
