The Marantz 300 disk CD changer does not have a coax digital out. It only has a toslink digital out. I ordered one about 2 weeks ago because the Marantz website says it has one of each. Again, it does not. Luckily I did not have to keep the changer. I called Marantz about it and they said it was a typo on their website. Their DVD changer probably has a coax digital out but I wouldn't buy it for CD play back only. I am now running my 2 year old Pioneer 300 disk changer through an MSB Digital Director and then through an EVS Millenium II DAC with very good results. The Digital Director lets you input a toslink cable and output a coax cable. It is also supposed to be a jitter filter. I've also been told that a coax digital out can be added to any changer for very little money but I don't know anyone to reccommend.
