    Why use a DAC?

    I was looking into the DACs and was wondering why way back in the late eighties the cd was all the rage due to a totally digital reproduction/signal to reciever. Now this DAC converts it back to analogue from digital, so whats up with this going back to analogue?

    well, unless you can hear binary, digital signals arent very useful...

      Cowanrg is right, u cannot hear digital signals.

      Digitizing audio provides a medium to transmit analog data source (i.e. the band at the recording studio) to desination (you, the listener) without any loss in fidelity (ideally-speaking).

      Another benefit is that it is mathematically easier (and hence cheaper $$$) to convert continous (analog) signals in the discrete (digital) domain, manipulate them via DSP's, and then convert them back.

        So in other words, using a cd/dvd player and connecting it via a toslink/coax cable to the reciever so data is not "bad" when the reciever interpets the info to analogue? I'm guessing that an "off-board" type DAC(ie: DAC-1) does a better job of this compared to a reciever...
        I wondering if I should use an "off board" type DAC with my cd player?

          Well you can either:

          (1) Buy a receiver that has a better DAC
          (2) Buy a cd/dvd player that has a better DAC (use analog outputs)
          or
          (3) Buy an external DAC

          If your not happy with the sound of your system then, any one of these options will likely improve sound but it ultmately depends on your ears and on your budget.
