"They design stuff in attempt to do as little damage or interference of the initial signal as is possible."
This is a good design principle when it is applicable. To apply this principle you have to know what the original signal is, so you can compare your output with the input. Unfortunately, in a sampled system such as digital audio you can not know what the original signal was, since you have only a sample of the input.
In some cases it is not hard to make a guess as to what the input signal was before it was sampled. In those cases, it is easy to see that the NOS approach (with no analog filtering) does not produce an output that is anywhere close to the input. In these cases there is no doubt that the original signal was damaged.
