And here's the issue, to some degree. Everyone here has owned (or at least heard) every notable thing AKG has ever made. K1000, K340, K240, K701, etc. I even have a K81DJ, which was first heralded as "the closed Grado". We know the lineup, and for the most part don't care about anything but the 340/240 and the K1000, all of which are out of production.
There's nothing wrong with your journey through headphones, we all made one more or less in public, but this is a tough place to grow up. If you want to stay, be warned that anything related to your "kopfhörersroman" (You are welcome, Dusty) will be met with some skepticism.
Also, the notion of burn in is total bullshit.
