Hah very cool, id love to see those measurements, beyers with leather pads, phew
I really like the Dekoni LCD Velour pads on the Audeze EL-8 and Hifiman HE-400i. Smoother treble bigger soundstage breathable massively confortable(after redycing clamp a bit on the headband) and something about the thick memory foam and tighter knight velour maybe doesnt impact bass as much as most velour pads.
Another user posted measurements with the lcd2c and you can see only slightly rolled off bass and much smoother treble. The smoother treble equates to better imaging as well.
