Different MQA DAC applies different parameters of correction during MQA rendering of the same MQA music. This is why it is tied to DAC hardware. This is why it is hard, if not impossible, for a computer software to do full decoding, because you need the profiles for different DAC. The profiles are only obtained by sending a DAC hardware to MQA Ltd. as part of the MQA certification process, resulting in a MQA DAC for which a profile is created - so you don’t need the computer software to do the …
