About this one …
I believe you probably mean this?
If that’s what you meant, she only wrote that someone on Facebook said it sounds better, after the OP of the thread asked how it sounds. Reads like a guarded marketing statement to me. Of course, there is always someone saying that it’s better, just like there is always someone saying that it’s worse. The quote, though, is not Naim saying that there should be an improvement.
However, it does make the good point that they listen to it and wouldn’t release it if it sounded poorly. (And we do know that there is some optimization being made, it’s pretty well explained in the Beta room; just not as big as people make it out to be. As I’ve said in the past, I wish that Naim made this explanation public)
