I'm currently experimenting with my butchered pair of DT 1350 to improve the damping inside. I'll report to you back when I have something, but I can say that I actually prefer it with almost everything removed :
- the damping plate on the back of the cup
- the sticky filter that covers the holes on the back of the driver
- the side filters
- the pads filter.
I've only kept the tissue in front of the driver.
In this position the DT 1350 becomes massively dynamic, yet retains clarity, which shows that the main culprit isn't the small driver, but the damping inside. I don't think frequency response changes much, but the sound is just fuller and feels "liberated". It's no longer thin sounding in the slightest and doesn't feel over damped anymore.
in fact I've also listen to it in "open mode" : by putting the two driver plates up to my ears. In this configuration I thought the sound was perfect. Once back on the cups, the sound felt as expecting more "closed in", with unwanted reverbs. But I still preferred it this way than with all the damping inside.
I'm not saying that it's better though, just different. There is still something wrong in the sound to my ears.
But I'm sure the DT 1350 could have been made substantially better with a better cup design.
