Sorry to muddy the waters on this discussion, but I have just been talking to
the service department at Sennheiser UK. I was very surprised to discover that
the capsule on the MKH-60 is close the tip of the mic, and NOT as I had
previously thought further down the tube. I was so surprised at this that I
pressed the point to be absolutely certain I was understanding him correctly.
This means of course that the picture on the link you give for the 60/30 shows
an incorrect configuration.
