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!

Interesting thread. I'm getting my system setup again after years of sitting in boxes. Lots of traveling and a move. With WFH likely to be my new normal it seemed time. I've been listening to CD's in rental cars until the last few months when I've been unable to get one with a player. I listen to ripped CD's on my workstation while I do work from home, or Photoshop (I'm a photographer) or Davinci Resolve, etc. I work in tech so work with server, databases, etc. As I'm setting up my listening room, I was looking into redbook players and found this thread about streaming. After reading the histrionics required for streaming I'm definitely going to stick with physical media. The other issue is that I'm thinking that a "no-internet zone" would be good for sanity in these times. I've always preferred the singular experience that comes along with an LP or CD that needs to be changed. Keeps me listening to the thing I've chosen rather than a stream of content flowing in the background. Probably another focus approach to keep me sane.

The idea of what sounds better is a concept that lost interest for me years ago when I realized that I was spending more time listening to the same few reference CD's to try out all manner of: cables,  power conditioners, gear, pucks, what have you. These days I just want to kick back and listen. Now excuse me while I go and obsess over what cheap redbook player to buy since my Micromega Stages haven't survived the move.
Letch,
me too. My wife and I play albums and cd’s while sitting on our couch. We like looking at the covers and album notes, we find it very relaxing, and we connect. Streaming is good for background music so I’ll want to keep it as an option.
I think it's a good option to have. Just wanted to chime in and rather than take a side over which may be "best" just point out that there are different modes to how we can listen as well as ways to listen. You get it.
