Oppo BDP-105 and Qnap TS-251A


I have recently bought a Qnap TS-251A NAS and attached it to my home network. My Oppo BDP-105 sees the Qnap and all its files on the network and, using the Oppo Media App, I can play the music files. I do not know what path the signal takes from ethernet cable in to the stereo audio out on the BDP-105. Does it go though the DAC?

The Qnap has 3 HDMI ports. It would seem to make more sense to attach the Qunap to the coaxial DAC input of the BDP-105 so that I can be certain of a direct path through the Oppo DAC. Does this make sense? Is this possible?

@noble100 - do you just connect Ethernet port of Synology with Ethernet port of  OPPO ? Does you Synology device contain some kind of network hub? and why do not connect OPPO to a router you connected Synology NAS to? I have Synology 414 and did not know about that type of functionality (it does have 2 Ethernet ports, but I thought it is for doubling the speed with routers supporting such feature)...
Interesting.
mikaelkuz,
     
    My mistake, I gave some incorrect info on my last post. I have the Synology 112J and just switched from AT&T to Comcast/Xfinity as my internet provider.  The new router/modem has 4 ethernet inputs so I have the Synology connected to one and the Oppo connected to another of these.

Sorry about that,
