Class D power amplifier---what about class-D CD?

No, digitization is representing those quantized levels by numbers
(these are the digits). Quantization is just quantization, nothing
more. It is a jaggy waveform.
Not so. Think about the _meaning_ of digital.
Sampling and digitization are separate and independent
phenomenon. Perhaps you are unaware of CCD aka.
"bucket-brigade" which is most certainly *sampling*
but also most certainly ANALOG and NOT digital.
In fact the higher-capacity flash memory (EEPROM)
is now making use of the technique of storing two or
even four different charge quanta in a single cell in order
to store more than one digital bit per memory cell.
