Hi,
I have the same cd player, but the rest of my system differs a lot (using dac/preamp/power amps *2). So i am using the coaxial output to go to my dac/preamp which makes better analysis.
In your system, by all means you should use the XLR option, which will give you without a doubt better results. A more controlled sound, with less distortion at higher volumes, which in return let you appreciate a more neutral and refined sound. Usually tighter bass and open medium and highs. Both your components are great stuff, using the XLR will let appreciate the greater part. Hope to have helped.
