    I bought a used pair of these headphones from the famed 'Sonus Faber,' apparently they're a amazing high end Italian loudspeaker manufacturer but I had never heard of them [​IMG]

    Anyway, the headphones are WAY too warm sounding and the presence region is really scooped out. To my ears there's so much missing treble I can't keep listening to them so I'd like to mod them, anyone have advice based on the pictures of the internals of how they MAY react to some mods here? Any ideas on what I could try? What's not easy to see in the pictures are the 8 drilled ports (yes... 8) from outside air to the back of the driver at the top of the cup. Any advice on what I could try would be appreciated! Thanks!

    That doesn't look like not enough presence to me. It could just be that bass distortion shoots way up with these.

    One simple tweak you can do is to just go way overboard with dynamat on every surface you can stick it on, and see if that will help bring the response back to par. If that fails, then try to obscure the ports progressively with materials of varying density.
