I looked at the Bluesound Webpage. It looks like it connects via Ethernet and then outputs to either RCA or Toslink.
So, Yes, I think you need a DAC for your cd player, if it is only a CD transport and not a CD player. The former only plays the CD, the latter plays and deciphers the signal to the preamp.
Should you need a DAC, I would suggest a Schiit Modi or Bifrost Multibit.
Both are quite inexpensive and will provide you with excellent sound.
