May have been mentioned up-thread but having dirty diaphragms; dust, schmutz, not-been-serviced in many years, will exacerbate this problem that Philip talks about. Microphones, like other mechanical devices need occasional service. They work really well for lots of years, but they need a trip to their particular mother-ship every so often. I cycle through my mics in a sorta five year program, but admittedly, the ones that stay boxed up the most get less attention. I have heard that off-gassing foam in some cases (ha) adds to the problem but I hope the big-league players have sorted this out years ago. But I have never heard direct word fro Schoeps, Sennheiser, DPA, Neumann, etc that their foam is inert. Hmm.
