Dac for Adcom System

Does it make any sense to plug the xlr output of a adcom gcd 750 cd player into the xlr input of a outside dac? I understand when using the Coaxial out or the optical out but confused in regards to xlr. Please excuse me i'm no well informed in regards to dac's.
A better dac is a worthwhile investment probably in your case. I don't know the rest of your equipment though. Most dacs don't have XLR input but many do. They all do have a coax input though. The XLR digital output and inputs do the same thing as the optical or coax.
The XLR outputs are analog outputs on the GCD-750. The unit has no digtal output.
