Anyways...for joining this thread late, I wonder what "preventive measures"
you guys have thought of, since the Denons are at their end of life.
I hope it's not too late to start some modding on my ah-d7Ks !
It's never too late to mods these gems! Lawton can do his damping mods (or you can do them yourself), you can swap cups out (I have deeper than stock Teak cups made by a HeadFi member from SE Asia), put Lawton angle pads on it and even swap the cable if you want. I had BTG audio put a 5' Q French Silk cable on mine a couple of years back. Love this headphone.
