how do you know if you need a dac ?

toyo18, I know that Ayre made a high end CD player that could be connected to a computer and used as a stand alone DAC but I don't remember the model number of the CD player. Anyway, the DAC chip that was inside that CD player was their best, most analogue sounding DAC chip but it became discontinued because they were unable to acquire the parts. So my question pertains to whether or not you can connect your computer to your CD player?

I have the Ayre QB9 DSD DAC. I believe the DAC that Ayre uses in their CD Players is equal if not better sounding. Are you certain you can't use your CD player as a stand alone DAC as well? If not, I'd call Ayre.
