Well, agree with the first part - bought four of them just for drivers, made custom wooden shells etc. But one u70 remained, and I know what's the main problem with this - driver is totally closed and just needs some air - simple overdamping, there is even thick felt here already, two discs on each driver. Basically, few holes around perimeter, under aluminium cover, can make those sing. And new earpads, of course. Will post some pictures soon.
