Well so many have written on the topic of lossy/lossless concerning MQA:
John Atkinson:
"Some critics have complained that the limited word length used to encode data above the baseband Nyquist frequency of 22.05kHz or 24kHz is equivalent to lossy compression of those data. But as I explained in my 2014 website article, if you look at the spectra of music recordings, they all follow a self-similar characteristic with respect to increasing frequency, the content decreasing in amplitude up to 60kHz or so, when it blends into the analog noise floor. So if you remove the baseband data, the remaining ultrasonic content can be encoded with fewer bits. Only if you then decode the limited-word-length data at the full-scale baseband level could you consider the encoding lossy. But if the peak amplitude of the limited-word-length ultrasonic data is reduced to that in the original recording, you do preserve those data's full resolution above the original analog noise floor.
Case proved for the music origami aspect of MQA, I feel. However, the only way of testing the second claim—of MQA's correction of time-domain errors—is through listening."
