It could make sense, since the only supplier removed the MQA flag on remaining MQA's files and WiiM no more recognized them.
In the meantime, however, I can't get rid of it, since the former MQA files have remained the same (flags aside) and the NAD Dac continues to recognize them, activate decoding and play them at 88.2KHz, a frequency that sometimes causes the NAD Dac to fail when Dirac is active. This happens whether you use the WiiM mini via Toslink or directly via Bluos. Known problem, WiiM support would be needed...
