Dynamic Comparison of LPs vs CDs - Part 4 - page 5
Genesis Ch.1.V.32 from I Robot (The Alan Parsons Project)
I did a digital rip of the 96/24 data from the DVD-Video side of the Classic HDAD release, and compared with the 96/24 recordings done using my soundcard of:
- Linear PCM 2.0 96/24 version on the DVD-Video side of the disc
- MLP 2.0 192/24 version on the DVD-Audio side of the disc
- LP

Note that despite the LP having a lower Total RMS Power , it has a higher Maximum - Average RMS Power . Subjectively, the LP does sound slightly more dynamic than either the Linear PCM or MLP versions on the DVD-Audio disc, but the DVD-Audio still sounds quite good and arguably "cleaner" sounding than the LP (ie. less distortion).
