Network Transport vs. CD Transport


So I decided to conduct an experiment. I pulled the old Marantz cd player circa 1999, around $400 retail, from storage along with few CDs. Using a coax digital cable with a $4.97 rca to bnc adapter from amazon, I sat down to listen. I played the CD, the ripped version (AIFF) of that CD, and a Qobuz redbook version thru my zmac Mini. Long story short...the reason why I did it was because there is something missing in the Mac Mini sound quality and I got tired of trying to figure out what the heck is going on. 
Anyways, that old cd player used as a transport into the Qutest DAC sounds considerably better  than the Mac Mini that right now I will need a few days break before I can can listen to the Mac again. I figured (assumed) that a dedicated network transport will pretty much better the Mac Mini and be comparable or better than what I heard with Marantz player as transport. Eyeing Auralic G1, Lumin D2 and Lumin U1 Mini as candidates (I need wifi capability), will any of these be comparable or better than let’s say a decent CD transport feeding the Chord Qutest? For example a Cambridge CXC, or a used high end player?
I can go back to spinning CDs, but figured I don’t want to give up on streaming just yet.
What are your thoughts - Auralic G1, Lumin D2, Lumin U1 Mini, or a dedicated CD transport for high quality playback. Forget convenience, let’s talk purely sound quality...thanks!

yup...thought about google wifi mesh. It’s an option. The reason why Auralic Aries G1 peaked my interest is because it potentially sounds better via wifi (Darko talks about it in his review on youtube). With all the wires I already have behind the component rack, adding more is not too appealing, but I am not opposed to it being an option.
@mountainsong Lucky dog!  That looks like a nice piece and to me the perfect bridge of being able to decode the MQA stream from a Node 2(i) and also spin SACD's and CD's.  Could also serve DAC duties for the TV audio.  

How did you manage to get it so quick?

I don't understand why you have crashes. You probably need to do a clean install of the OS and associated applications. 

I initially used an iMac and a MacBook Pro to wirelessly stream my lossless ripped CDs for over 7 years and switched to a Mac Mini running headless for the last 3 years. With over 10 years of use, I have never had a crash or any issue with any of my Mac computers.

Could you please clarify...the Aurender, streaming from Qobuz, does not match the sound of your Luxman D-03x? Is the Aurender driving the Luxman on-board dac?
+1 For Etherregen,  total game changer in my system streaming from apple TV 4th gen and Spotify premium direct to Lyngdorf TDAI3400.

I am constantly amazed by the SQ of some of the material on you tube.
