AKG SE300 mods?

[Icantthinkofaname]

Any mods for the AKG SE300/Blueline microphone (and maybe the CK93 capsule)? Maybe something to lower the self noise? Or would that be from the capsule since it's an electret? Interested in them because they're really cheap used.

Bumping, I've been considering picking up a couple of these mics since they're pretty cheap used. Same question, is there something that could be done to lower the self noise (besides a high cut cause I think they're supposed to be quite flat). Or could sensitivity be increased by polarizing the capsule?
