I've concluded that the implementation of ear pads is even more crucial than good damping.
I've been playing around with many different ear pads and materials that i've got lying around.
Old flat grado foam pads for example, give a very clear bass light sound. Scarily gradoish. (closed using my damping scheme).
Various pleather pads all drastically boost the bass response.
So I think I might need to create my own earpad with fabric and open cell foam on the inner/middle circumference and pleather on the outer circumference.
Hopefully this will give the best of both.
I ran across some round pads from an ebay seller that had fabric below and pleather on the top half surface , but i cannot recall which they were, It bothered me so much i sealed the fabric with plasti-dip, if i can find which they were I will at least post whether or not they were of use in your particular config.
All this Dual/Magnat talk is getting me excited again.
Got some HM5 pads on the 830's but they seal up too well and create a suction. I did seal the driver perimeter to the baffle though. Managed to get great bass and tuning doing that. I'll look for another similar shell and try a driver transplant to make a fake Magnat/Dual headphone .
they were actually nice pads.
Found them way back in 2012.
These pretty sure. See the closeup there is fabric lower, pleather upper.
