My newly received Lambda Signature need new mineral wool as they have had the dampening removed (eBay reaming). They do not sound very good that way to me (worse then the Lambda Pro). The foam behind the pads is half disintegrated also, so I'll also have to replace the pads with a pair from audiocubes II. I don't think they have the brown pads like these though, bummer.
Any leads on finding these materials?
