Has anyone tried removing the center cloth of a Denon D2/5/7k stock pleather pad? I'm using them on my woodied T50RP and I think the cloth is causing a recession of the mids, particularly in the vocal range. This might also be responsible for the mid recession we see on the Denons, as I've found that pads can have a very large effect on what the general sound of a headphone is (see: Sony XB700, AKG K701, Denon D2000).
I don't think the cloth is sound-transparent, as when I try to "speak through the cloth", it doesn't sound normal. Ideally I'd like to replace it with some sound-transparent speaker cloth, but I don't have any on-hand and I don't want to destroy the Denon pads if I don't have to. I'm just wondering if anyone else has tried this and verified my hypothesis about the recessed mids.
Here's a pic to show what cloth I'm talking about.
I'm considering asking Jmoney audio to see if they can make a customized Denon pad that either doesn't have the center cloth or has a more transparent acoustic cloth, but that's money I would rather put towards O2 pads...
