I have auditioned and owned a number of Aurender streamers at the three major levels of the N class. There has always been a very consistent and “worth the cost between each level”.
The new N2 class has been reported as being a significant upgrade… so I would be willing to bet the N20 is absolutely worth it. I still own two Aurender streamers one a W20SE. If I was in the market for one of the two you speak of, I would unhesitatingly buy the N20.
This comes from an understanding of the company and there products, but not having actually heard a N2 class streamer. But having read positive feedback that is completely consistent with my experience with the company.
