I use the Telinga Pro V with the stereo mic element they design for it.
I also have the mono dual science element, which I rarely use. Between
those two I find little difference in sensitivity. This may be due to
the stereo mic setup being a boundary mic design. In any case I've seen
no reason to loose stereo to gain sensitivity. Faint sounds is where
stereo really helps.
Note that the Telinga's stereo is a mix of local and far field. I kind
of view it's field as being pear shaped, with the stem being the far
reach in center.
There was considerable stir in the group a little while back on stereo
parabolics. My feeling is that optimizing a stereo pickup in a parabolic
is a little more challenge than optimizing two mics without a reflector.
But it's well worth it.
I've got a few ideas to try when I get some time. Requires some
machining to do.
