Novice dac query.

dear all.
Can i use a dac with my droplet cd player? it has a coax cable out ( i think thats what its called). would this bypass the internal dac/ valves? i see a few dCS dacs for sale. they are not cheap for something in the regoin of 10 years old. would it better the one one in the droplet? i would think so, given its preowned price, but would like to hear what others think. to me, the droplet is very good sounding, but a upgrade in sound would be a good thing. thank you.
