Half the information on CDs is analogue

I would like to argue that one of the reasons that some transports sound significantly better than others is because much of the information on a given CD is actually analogue (analog) information.
An excellent transport does not just read digital information: 1s and 0s (offs and ons); it must be sensitive enough to pick up the other information that has been stored as a physical property of the CD medium. This 'physical' information, like the tiny bumps in the groove of a vinyl record, is analogue information.

Before I say more I'd like to hear what others think.
