Although I presume you are talking about a "jukebox"-type rather than a 5-disc changer like mine, I can recommend using a Monarchy Audio DIP in between, as I do with my Adcom GCD-700 changer and Theta DSPro Basic IIIa DAC. It seems to largely ameliorate the most glaring shortcomings of a low-budget transport when used with a good digital interconnect (mine is Cardas Lightning). I'm able to run a S/PDIF output from the Adcom, but you may have to use a Toslink into the DIP, then take coax or balanced out to the DAC.
