CDs have the information to perfectly reproduce frequencies up to the limit of human hearing. But to do that perfect reproduction, you need to sum up the sinc functions for all the samples. CD players do not do this.
As the article points out, the sum of sinc functions constitutes an extremely non local spline. And analog filtering of the stair step function coming off the A/D converter is not equivalent to summing the sinc functions.
