    6-MQA is proprietary DSP. It is an applied digital filter. It is a post processed version of the mastered file, removed by one generation,
    and distorted....
    Point 5 must be expressed incorrectly, since one needs a sampling rate of at least 96 kHz to get a frequency response to 48 kHz, so the 24/96 (at least) isn't upsampled

    Point 6 is mostly what I and others have been saying all along, although describing it as "distorted" is clearly misdirection. It is distorted only in the sense that it is changed from the original, and not necessarily in a bad way.

    Yes agree

    Bit of fake news here

    Of course there actually isn't much musical content captured above 48khz, other than some timing information

    Agree about alleged "distortion"

    all upsampling algorithms add, and filters create issues , which can have elements of distortion, its not desired, not specific to MQA, as always in engineering there are trade-offs

    True. You don't know what I've heard.

    From what I understand, the MQA seminar at RMAF 2017 is cancelled.

    That is an excellent question...
    In a perfect world, the two should be exactly the same, the speaker should convert the signal without any distortion whatsoever..pity that this is so rarely( or maybe ever)the case!

    To answer Alex's question as to why I started this thread( and the point of it)....well for me it was because I had heard another factor regarding MQA that was of concern to me (along with similar points to those that MQA Truth posted)...and that was, that it was potentially nothing more than a scam!
    Therefore, I thought it may be appropriate and more honest to a) discuss this possibility and b) alert those that were impressed by the demos...like myself, that perhaps there was something else going on. Something else that was not quite so obvious to all. Including myself and Alex!!

    Alex does not seem to share your newfound concerns. I am curious about MQA Truth's identity and the motivation behind his post. And I would welcome the contributions of your digital expert friend to this thread.
