Purpose of a DAC and Redbook Presentation


I have seen DACs on audiogon. What is their purpose? Who would benefit from buying one? What does the term "redbook presentation" mean?

Purpose...The DACs you see are "outboard" units that can be substituted for the DACs that you already have inside your disc player. In the bad old days, players often had inferior DACs, and sonic quality would be improved by using the outboard unit. But, beware! The quality of run-of-the-mill DACs has improved greatly in the last year or so, and even an inexpensive player may have DACs superior to an expensive outboard DAC that is a few years old.
If you do not have a coax out on your cd player forget about a dac and get a new player. toslink sucks.

Wish it was like that.Some older top of the line Dac's are still holding strong.
yes there is a benefit but you also need a very good digital cable. The other option is to have your CDP internal DAC modified.
