The tabled SACD data is questionable!
Firstly there is no question about the potential clipping of the CD data shown in the table and in the waveform display, however the SACD data was redigitised from an SACD player analogue out at a max. level 0f -3dBFS - any potentially clipped sample information has been lost in the re-sampling process! It was then normalised (amplified) to give a max. single amplitude of 0dBFS.
I don't think the two data sets are able to be compared becuase the SACD data is not what was on disc!
I do think the conclusions are correct however, because of the visual difference of the waveform displays, i.e. the CD waveform clearly has had more gain/compression applied to it than the SACD waveform.
