I thought I remembered something about that when I started getting into CDs, or maybe in my music recording classes in college. I had to look it up to see, but it looks like 16 bit audio CDs, the standard, have a dynamic range of 96 dB with possibly a higher perceived range once dithering is taken into account. Compare that with vinyl at approx. 55-65 dB and CDs do have a potential for more range. However, CD's are also more suited for the "loudness war" since they won't skip like a phonograph needle would with heavy limiting and compression. Despite dynamic range being wider in CDs, the capability of being able to handle louder music helped push the loudness war along.Interesting vid... Alan explained his concept very cogently and sure makes it much easier to grasp with what's going on.
Side note that may be a bit off topic but, Alan mentioned that for compact discs, "For the first time the history of audio, the dynamic range of the medium is wide enough to capture the dynamic range of music with no compression." So the dynamic range of the CD medium is larger than the dynamic range of the music... I was led to believe that a major criticisms of CD's was that they required heavy compression (maybe to fit the length with a smaller file size/resolution rate???) and therefore couldn't match the quality/fidelity of a pressed album. I remember Neil Young pushing that idea pretty heavily when he was trying to get that new playback device launched.
