I can not understand such argument. We have now been told there is currently material enough, even freely available, to carry such comparisons. Any one having an MQA certified DAC can do them. But people prefer to go on commenting audio gossip and other people opinions than listening and posting their own facts and opinions.
A few months ago, having read a lot of technical arguments and opinions against DSD I was not particularly interested in the format, and did not have an opinion or cared about it. However after listening to SACDs in my system for sometime I started valuating DSD and today I would be sorry if my DAC did not have native DSD playback. Surely my opinions are limited to my gear, but I have no problem admitting that experience changed my views about the subject.
IMHO, in this particular case of MQA, having an open mind means having open ears. There are too many emotions and interests behind the arguments being shown.
