Very good.
This is besides the point / a different discussion. I was talking in theoreticals to help convey the point about "improving" vs "not degrading". We are already struggling to understand each other, so I suggest we don't go down that road, at least not at the same time.
It may help to read the post I was originally referring to:
Bit perfect this week will absolutely be different next week ..! :) In a strict sense, "bit perfectness" is very easy to check. My DAC, but others have this feature as well, has a build-in "bit perfect" check. You can verify using short samples that a source is bit-perfect or not. See here...

It contains some interesting claims about 1 and 0 being different in audio as opposed to in the IT world, and also that it is possible to clean and refine the ones and zeroes. Those are both examples of false claims.
He also adds that the signal can be accurate (I assume as in the ones and zeroes being similar to the original), but still be less refined, whatever that means.
This is not how any of this works.
A state of a bit can only be 1 or 0. There are only two states, that is literally what digital means. They are not like sugar. They can not be impure. They do not need cleaning. And they cannot become any more clean that they were to begin with.
The only way to come up with this, is by making it up. Why one would like to do that, I don't know.
Does audiophile network components that reduce noise and subsequently reduce degradation of the signal exist? That may be, but they don't work by cleaning or refining (improving) the bits.
