i already had this sense, but just to make sure........i took 30-35 minutes of my life i will never get back, and did a 20 second A/B on Tidal with MQA and then Quboz with standard PCM......with 10 cuts. 100% of the results were exposing MQA as slightly smeared and less vivid.....mostly less separation of the soundstage, and somewhat dynamically muted. none of the MQA were 'bad' musically. just less special.....less alive and real. some of the Quboz was regular 16/44, some the same resolution as the MQA upsample. same result regardless.
maybe some new stuff is mastered with MQA, maybe that makes a difference.
the whole idea of MQA is to 'fix' digital somehow......we already know we don't need to fix it, we just need the Wadax. but honestly that was the similar result with MQA on the MSB, maybe to a slightly less decisive degree. it was a little closer.
