Upgrade my CD player or futile effort?

You guys are the best! A lot of very good advice from many different directions. The one that resonate to me is do one improvement at a time. Been guilty of not doing that in the past. The other one that comes back most often is get an external DAC and keep the current  transport. I am totally in line with that. I spent quite a few hours now reviewing my options. It seems that the starting range that may please me in a DAC is $700. Of course it can get better from there, but that may be enough to get my toes wet. Anyhow, so far I am considering the following:
-Schiit Bifrost 2.
5 year warranty and 15 days return!
-Denafrips aresII
-Topping D70S, (the D90SE may be too revealing for my system)
-Musicians Pegasus, sounds like a winner, but reliability questions with a brand new company concern me. 
Some other DACs in that price range mentioned here include headphones preamps which I don't need since I have the Schiit Asgard 3. No sense paying for that. As I said earlier streaming won't be for me, I need the tactile part of my music collection. Over 2,000 vinyl and about 400 CDs. 
So just need a simple no bells and whistles straight DAC with RCA out and coaxial in (no optical, got it!) and will hook it up to my Prima Luna 100 tube preamp. I just have to decide between those based on sound characteristics which can get overwhelming in the many reviews. Please chime in some more if you experienced the sound of any of those. Thanks to all.

@oldaudiophile.Yes, I have it set to audio EX 2, always have. It still is not in the league of some of the new DACs from what I now understand.

Lumin U-1 mini = 2000.00

Your DAC of choice @ 1000.00

Synology NAS = 500.00

Rip all your seedees to the hard drive and enjoy. You can also stream Qobuz with this set up. Hands down better than any cdp you can buy at that price. But in the end, your vinyl rig will probably still win the day, just by not as much.

As Yakbob has stated clearly, and others have said, you have a huge imbalance in your digital vs analog. Who do you think a $500 mediocre even at that CDP will compare with your TT costing > 10X that? I mean digital can be great, BTU its not magic....

So why do you believe it might be futile? share.

I wont repeat the pages and pages that i have posted on how to get digital to sing, nor can i quote all the others who have, in thread after thread given of their knowledge. But rather than ask a superficial question, I’d suggest reading that trove of info.

Bottom line, while the are different, i generally prefer great digital to great vinyl, in part because the great music may not be on audiophile vinyl, but it may well be remastered on digital. I’m talking 10s of 1000s of titles on, say Tidal or Qobuz.

While it is much more complicated, i can also say that without question, streaming can be superior to any CDP, **all other things held constant**. You know, one variable per equation.

You will spend vastly more money than you have so far on digital, and even more in terms of time and effort to get it right. yes, there are many ways to get digital wrong. But i can get truly great sound with <$1k DACs. Beware though, i may have that much or more in stream, network, bridges, and idolators before it hits the DAC (USB - SPDIF has issues).

Will digital sound like analog? Honestly no. In many ways it will be vastly better. In others it will fall short of some euphonics.

I was an analog bigot until a couple years back. No more!
