I hear the story on microphones for Dolly Parton is that here voice is so  hi 
pitch that she goes in a tries a couple dozen  of the exact same  microphone 
and finds the 1 or 3 that don't resonate with her voice. and she gets  them.  
I  here that finding her a compatible mic is difficult due to  the pitch of 
her voice..
 
Just rumors, but seeing how T.T is on D.P.  parkway.. this is now  relevant  
:)

Right  you are, Bob. The "dirty little secret" in the audio world is that  
transducers, ie, microphones, speakers, and yes, even (I hate to use  
this word now) headphones are highly variable compared to the  
electronics that they connect to. I know recording engineers that will  
go through and test a distributor's entire stock of a particular  
microphone before  selecting the one or two deemed best for a  particular 
recording session. Variations in temperature,  humidity  and barometric 
pressure also affect these devices in various measurable  ways. These 
differences can vary from "barely detectable to a very well  trained 
ear", to "wow, I can't believe that's the same make and model of  
(whatever)". Complicating matters even further, our ears are also  
affected by these environmental variables, as well as having frequency  
response and sensitivity profiles that are as unique to individual  
humans as fingerprints are. That's what makes all of this so much  Fun!

Case and point:  for one of my sound applications I  purchased 5 
professional
mikes of the same brand, same model, from the  same place at the same time.
They are not consecutive serial numbers but  for all practical purposes, the
same.  In a critical listening test  with these 5 mikes they all sound
different.  Oh, not much but to the  trained and critical ear, different.
All of this has to do with the tension  or pressure on the diaphragm during
manufacture of the elements.

So  how does one get a good sounding mike?  Unless one is willing to  
purchase
several and do critical listening tests under controlled  environments it
becomes a chance of the draw situation.  You get a  good one or you get one
that doesn't sound so good.  That then depends  on the listener and their
evaluation of "what sounds  good".
