Which Has Best Sound Quality -- CD vs. Tidal vs. FLAC Uploaded From Burned CD

I will start the discussion noting my experience using Roon and Tidal, which enabled a direct A/B comparison between my FLAC library which I transferred from my CDs and Tidal.  It was easy to A/B compare because in many instances I uploaded the same album in FLAC that Tidal had in their general mainframe for our listening pleasure.

As an example, I listened to both versions of the Ratatat album LP3.  I found my FLAC version superior to the Tidal version based on being crisper, more refined and less bloated in the bass.  The Roon software clearly identified that I was playing the same album from the two different sources.

I have not compared the CD, as this would require adding a CD player.  What has been your experiences in this area?

Tidal MQA (compressed 92kHz/24bit)> CD (original 44.1kHz/16bit)= FLAC (lossless 44.1/16)

I find this question DAC dependent. What do you use?

Cary Audio 200ts -- quite nice with a tube option. 

Since I was using the same DAC for both my uploaded FLAC versions of various albums and the same albums that loaded directly from the Tidal server, I think this eliminates the DAC as the variable which might explain the difference in sound quality.  It is interesting that with the Tidal 19.99 a month expense, one is supposedly getting the same CD quality as one of my CDs transferred to uncompressed, lossless FLAC.

Gear dependent so the question is really not answerable.  System by system variance is a reality here.

Just because there is system by system variance, does not mean that taking a poll on this issue would not have any validity.  It is very simple, using all your components exactly the same way, a/b compare Tidal CD quality versus your own uploaded CD of the same album.  You may say Tidal sounds better or you may say your own uploaded CD sounds better.  It would be interesting to know the results.
