OPPO 105 as a streaming source/transport only


Ok, so here's the deal. I have an OPPO 105 that is approximately 5-6 years old, I bought it new. I now use it for movie night(rarely) and as a transport and streamer to my Wyred4sound DAC 2V2 SE. I mostly stream Tidal for music. My question for all you digital gurus is this, with my wireless router to the OPPO am I losing sound quality? I would have an approximate 45' run of hard wire from the router if I was to go direct. If I wanted to experience notable sound quality gains. What would you do/buy for said gains? Yes I know get a turntable, that's not really for me at this time. Thanks!

It's probably obvious that I don't know what the hell I'm doing, so how about a little advise, thanks.  
I ran CAT5e all over my house a few years back so everything is hardwired. My Oppo 205 plays flawlessly this way. There’s probably a couple of hundred feet of wire between my house and my office next door all connected to my home network. There’s no noticeable degradation of sound.
Generally, a wired connection is preferred to wifi. But if you’re not having problems with dropouts, etc. I’m not sure wiring would give you a major boost.

Play a CD through your DAC and then the same album from Tidal through your DAC.  The streamed version should sound as good as the CD.  If it doesn't, a wired connection should help.  If it does, start saving up for a DAC upgrade, or whatever else you might want to upgrade.
