Thedautch, some players do have a higher quality Stereo outs, some don't. In the case of your Pioneer 563 there is much better DAC used for the Stereo (DSD1791) and worse used for the MCH (DSD1702). The good part is that the Stereo and the Front L+R channels outputs are literally the same thing - they are paralleled. So, it does not matter where you will connect your cables on the back (Stereo outs or Front L+R outs) you will get the same sound quality because both are processed by exactly the same circuit.
In the Denon 3910 all DACs are identical but only the Stereo/Mix channels have the higher quality filtering circuit. The Stereo output in the Denon can not be used for Front L+R MCH outputs. In one of my entry line Denon 3910 re-designs I am changing this so the Stereo becomes also the Front L+R output for MCH. Of course the MIX is disabled but MCH recordings don't sound good mixed down to Stereo anyway.
Yes, it will be ok to use Firewire, HDMI or even the Coax Digital for movies MCH playback and stick to the high quality Stereo outputs on the player for critical 2 Ch listening.
