- MQA is not lossless in either stock or unfolded form. Regardless of original file sample rate.
- Most MQA releases are simply being upsampled, and are NOT sourced from high resolution masters.
- MQA aliases high frequency content down into the audible range with minimal attenuation.
- MQA does put back high frequency content, and remove the previously aliased content when unfolded, but leaves distortion and noise behind.
- Tidal no longer offers true lossless streaming for any track marked as "Master" that I could find. You either have compressed, or lossy MQA. The lossless FLAC is not available and you must use an alternative service such as Qobuz or Deezer.
- MQA 'authentication' and the blue light gives no guarantee of source sample rate or lack of alteration. And does not guarantee that the sound is the same as was in the studio
- A huge number, presumably most, of MQA releases are just upsampled and altered 44.1khz. Not Hi-Res
- MQA like for like offers no file size advantage, and is actually bigger than 44.1khz FLAC. Though is smaller than Hi-Res flac.
