Let me further explain the meaning of preference, IMO, with the help of the same picture again:

I made it smaller this time.
Let me state clearly first. All the following are
my own personal opinion.
All the 3 pictures are from the
same source (in my analogy, it is the 44.1k / 16 bit source)
For the first picture, in my analogy, it is similar to the output of NOS DAC
For the second picture, in my analogy, it is similar to the output of Modern OS DAC
For the thrid picture, in my analogy, it is similar to the output of upsampled music
Remember, they are all from the same source. I really like analogy... to me, it helps to explain to other people.
Let's think about cooking analogy,
the source (44.1k/16 bit) is the
recipes
the DAC is the
chef
the final music output is the
dish
The master lab give you the recipes for a dish. Your hifi system "cook" it for you.
I would not say my music is better or worse than the one from the master lab as they are
not comparable.
I won't compare a recipes with a final dish as I won't compare apple to orange.
ok, go back to the pictures above, let's use cooking analogy:
For the first picture, it's the final dish from restaruant NOS
For the second picture, it's the final dish from restaruant DAC
For the third picture, it's the final dish from restaruant UPSAMPLING
Again, let me remind you. They are all using the same
recipes.
Someone prefer to look at the pictures like this:

Someone prefer to look at the pictures like this:

Again, same source, same pictures, just different presentations.
Bottom line,
to me, I think it is all down to our own personal preference for what is "better music". Which restaurant you want to go to.
There is no right or wrong, correct or not, true or false, etc..
