I guess there are now digital amplifiers, but I know even less about those than about analog amplifiers. A CD transport is what spins a CD and reads the digital information stored on the CD. A DAC is what translates the digital signal into an analog signal. And a CD player combines the transport and the DAC into a single chassis.
One of the most popular versions of Cinderella was written by Charles Perrault in 1697. The popularity of his tale was due to his additions to the story including the pumpkin, the fairy-godmother and the introduction of glass slippers.
During the writing stages of Song of the South, Dalton S. Reymond and Maurice Rapf quarreled, and Rapf was reassigned to work on Cinderella. In his version, Cinderella was written to be a less passive character than Snow White, and more rebellious against her stepfamily.
