I posted my experiences in an earlier post somewhere. For the purposes of this thread I did a quick comparison of Renaud Capucon/Khatia Buniatishvili Franck, Grieg, Dvorak: Sonatas for violin & piano (which I have on CD as well).
- Bluesound Node 2 using internal DAC with MQA
- Quad Vena DAC streaming from Bluesound Node 2 MQA through optical.
- Quad Vena DAC from cheap Philips Blu-ray player playing CD through Coax.
The CD clearly sounds worst: in comparison the sound seems muffled (not softer; I tried increasing the volume).
The two MQA options in comparison are much clearer; it is indeed much more like the violin is in the room. I find it difficult to distinguish the Quad Vena DAC and the Bluesound DAC: there may be the tiniest of differences, but not quickly noticeable. Maybe I would find some difference after extensive listening, but then I might as well imagine things. This is in fact similar to non-MQA music which I also find sounding similar through either DAC.
Provisional conclusion: the improvements (if any) may in this set-up be due mostly to the 'remastering' part of MQA and/or the higher resolution once unfolded. The MQA-qualified DAC in itself doesn't seem to make much of a difference.

I also did a quick test using my Sennheiser 598 headphone (which I find quite revealing), again there is only the slightest of differences. Then I got bored and decided to just enjoy the music instead (lovely album, can really recommend it).
Following on my earlier post of 3 February (I've been busy lately) I've just quickly A/B'ed the MQA version vs the ripped CD through the Bluesound Node, listening only on my Sennheiser headphones.
There is not a clear difference between these two versions. Both sound fine, which undoubtedly is due to the quality of the mastering. After extensive comparing I believe that the MQA version offers more details, as I continually find that I can first distinguish details in the MQA version that only then i can also hear in the CD version. Then when comparing back these tiny details are more pronounced in the MQA version. It is in details like a slightly stronger vibrato, a bit more presence of the breathing of the violinist in the final track.
I would not call this a night and day difference, and I can live quite well with the CD version. Nonetheless I do feel that MQA has added value. Admittedly I would need more extensive testing to find out whether this is really not just psychology. Assuming that it isn't, the difference is slight. For other set-ups it might be easier to distinguish.
