What do you think makes NOS sound different?

You are taking my words out of their context and shooting from the hip.
I didn’t say they are better than the rest or being the only ones making good DAC’s.
They, as a company striving to play in the top league, must very well know that 100 taps are not enough for a perfect reconstruction filter.

You didn't understand what's written. Perhaps you need to understand what you are writing. "perfect sounding DAC" doesn't mean anything without the context and description which you didn't provide any and I filled it for you.
 
There are posts disappearing, maybe it got too medical - even though posts about supposed effects of ultrasonics are to some extent related to the topic of the thread.

Yes, Marcel, there certainly are. With no Moderation team notice or explanation. I don’t believe the posts violated any site policies. The subject is technically related to the thread, so, it wasn’t non-sequitur, or completely unconnected. Very odd.
