What doesn't add up is that out of all the headphones he's measured, its just that one he can't ? Its abyss.....they make the worse measuring headphones. I would blame product variation before I would discount the measurement. They don't market to people who care about measurements anyways. Obviously you can still like something that doesn't measure well. That isn't my point though.
I really wanted to like them because they're American and really cool in person. I EQ my headphones too. Yes soundstage for sure, but I also think all those attributes are better on the Arya as well. In fact when I got the arya I had to try the susvara, then I sold the susvara because the arya was close enough for me. To me diana sounded like a typical headphone, nothing really stood out and that is why I always compared it to the HD6xx. When I got the arya I was like "dayuuum".
