I'm still waiting for mine to be delivered so I don't actually know as yet, but I'd read somewhere that the balanced armatures aren't really affected by burn-in. With how they are produced and the way they work that seemed logical to me, is this not the case then?
All i can say, listen to it by yourself and decide. I know i ain't expert in this particular area, but my human ears and brain feel the difference.
We can't live by people's opinion, it's our opinion and experience that's gonna stick in our head. Just my 2 cents
