Maybe I should call myself Sapogee. ;) I've been listening for forty years. I have heard a lot of up sampling and oversampling cd players, and haven't really liked any. A friend brought over Audio Note's cheapest, the Zero. Immediately, I noticed something different. With a 1.1x, I found I was hearing the material in a completely different way.
As an artist, I look at it this way: Lots of people can draw fairly accurately, and certainly have fun tracing in every hair. Ah! but look at a Vermeer. See how sure his brush stokes are. There, his subjects have the look of three dimensionality; they look real. That is the the singular gift of the Audio Note's 0 over sampling.
Detail? I don't believe oversampling reveals more detail. To my ears, oversampling builds up energy in the treble. That gives the appearance of more information, because a lot of quiet stuff come to the fore, where it is more noticable. It also gives CD medium a bad wrap, one of being bright.
I run my AN through an extremely clear amp into extremly revealing speakers. If there is more info in those 1s and 0s I don't miss it. The band is living and breathing in the room. That is all that matters in my book.
