I'm not too hopeful that hardware mods will fix the issues. Traditional dynamics don't respond as much as orthos. Also the 5kHz depression is still a little bit evident on the foam coupler measurments. The treble is already laid back, so any additional attempt to put material in front of the driver may be worse than the cure. It should be noted that the treble sounds much better than measured. Nothing nasty, just not the smoothest and most refined. What the Elear needs is a pad that doesnt squish down and retains good distance between the ear and driver while still retaining an abosorbative interior to prevent the 1kHz bump (as seen on Utopia). Of course the abosorbative interior might also contribute to the upper mid suckout. It should be easy to access the area behind the driver. Will report back later on rear damping material.
