The problem remains with the need to filter content beyond the converter's ability to sample. Any and ALL content not filtered will necessarily be perceived as 100% distortion. A Nyquist sampler (non OS) must perform the steep and absolute filtering before the A to D converter requiring complex filters. In this case, it is not necessarily the simpler solution. Over sampling allows multiple filters used at higher ranges that do not effect the audible band to the same degree. Red Book playback must necessarily trade some bandwidth for phase integrity. There is an Ayre player which allows you to choose which profile you want for a given recording. Which is why hi-rez is inherently superior - because simpler filters can be used at far higher frequencies leaving the audible band completely intact. It obviates the technical challenges that transcend theory which does not work in practice.

Sir T is among many recording engineers who have taken the feed directly from mics and compared the result stored in multiple formats and found Red Book lacking. That is where the rubber hits the road, not the presentation of simple graphs.
