Someone brings up another totally 100% valid point that renders a lot of this theoretical hooey.
How good a job are the record companies doing with the mastering process?
For instance, I just got a gold CD of Pink Floyd's the wall. I also have EXOES, their new greatest hits collection. It says in there that they did a 24/96 remastering. Well, comparing the songs they have in common, the gold disc sounds better.
As to whether something is direct to digital - even in this day and age, most music isn't, but much is. Look at the CD and see if you can see "AAD" "ADD" or "DDD". The first refers to the original studio recording, the 2nd to the mastering, and the 3rd to the CD itself. Most CDs don't state this information. There is also the oddball "DAD" CD.
At the end of vinyls lifetime, some vinyl was touted as digitally mastered, as though that were supposed to be superior. (I don't have enough experience myself to vouch for digitall versus analog mastered vinyl.)
The digital masters they were using could not have been any better than DVD-A quality, and it follows from this logically that vinyl is inferior to DVD-A.
