What we can measure, only tells a small fraction of the story of what we actually hear. MQA is supposed to get the spatial queues better, like analog does. That, we cannot measure.
MQA = TBD.
Yes, but it may not be such a small fraction. How much better is MQA than other formats? That's the question. It has been suggested on this forum by people who have spent some time listening to and comparing MQA files to non MQA files.. even through such a performer as the Meridian 808v6... that the improvement is incremental at best. And it has also been suggested that MQA did not always best DSD.
From reports such as these it might be that the ''small fraction'' could be the amount of improvement that MQA actually brings to the equation.
While measurement does not tell the whole story, according to the article whose link I posted, MQA adds other other undesirable issues in order to get that small fraction of spatial improvement.
Also with respect to another issue that is being discussed, primarily by j2020 and Still-One, ie: MQA performance in a lesser DAC versus NON MQA performance in a higher quality DAC, I think that j2020 makes a valid point.
John Darko, in a review of MQA through the Mytek Brooklyn, makes the case that MQA is indeed better. But what I find interesting is that he feels that MQA through the Mytek Brooklyn is NOT better than redbook through the Aqua La Scala, he also states the he personally prefers other formats through the PS Audio Directstream Jr to MQA through the Mytek because he prefers the Jr's overall tonal quality.

And Still-One feels that his DAC outperforms the Rossini even when the Rossini is playing MQA decoded files.
Of course this is not comparing non MQA and MQA performance between two super expensive DACs like Merdian Ultra and Vivaldi as j2020 would like. But if Darko's assessment is accurate, this tells me that if you have a DAC that you feel is particularly fine sounding (which I think I do) you are not necessarily going to get better sound quality from MQA through some other DAC.
And this, both from a musically aesthetic sense and from an economic sense, seems important to me.
From a musically aesthetic standpoint, Many of us have spent considerable money and time dialing in our systems to where we truly like them. I for one am VERY happy with mine overall, but especially with respect to timbre, tonal density and quality. We all know how important synergy is and how changing one component can change everything. So if we have a system that we love, is it worth it to change the DAC for what might or might not be a small fraction of improvement with respect to spatial cues and at the same risk getting some reduction in some other area... eg., tonal quality?
From an economic standpoint, are we going to sell a DAC (taking a loss) that we think is truly musically great and then spend as much or more in order to get an MQA DAC that is in the same league as what we had in order to get an
incremental improvement (and, if reports are to be believed, in some files no improvement whatsoever)?
After the initial onslaught of ''WOW MQA IS GREAT'' reviews, reviewers seem to be taking a closer look at MQA... amongst them some who praised it very highly to start with... and the result is that opinions seem to be more varied and less enthusiastic. While they seem to agree that MQA is an improvement, it seems that with further scrutiny and comparison with other formats, they do not think it to be the overwhelming improvement that, at first, they were touting it to be.
Also I have read that a lot of manufacturers are resisting being pushed on to the MQA band wagon as they were with DSD. They feel that with DSD they had to respond to public clamor and implement DSD in their DACs or risk losing sales. The ones I have read about, at this stage of the game, say that they are not going to cave in to pressure. And some don't want to go there because they don't feel that MQA is intrinsically better than other formats.
Michael Lavorgna, sending DSD to the Brooklyn from HQPlayer heard the music to be ''sweeter'' and ''that much more spatially
right (Michael's emphasis) and relaxed'' than MQA through the same DAC.

It would seem that the jury is still out on MQA, not only due to the lack of content available but also with respect to just how good it is or isn't compared to hi-res PCM and DSD.
