All cd players have digital to analog conerters (DAC's) built in, no need to buy one. Seperate DAC's were very popular in the 90's, but not as common today. You would only NEED a DAC if you buy a cd transport, which reads the disc only. A cd player has both the transport mechanism and DAC built into one unit, similar to an integrated amp has both preamp and amp functions.
