Peter is it not possible to improve the sound stage using shuffling or othe=
r mid/side techniques? See http://www.urlme.net/blog/?p=3D1744

The SASS boundary would scale but as the size is reduced so is the boundary=
 effect and you move its effect upwards towards the high frequency region.

A tiny barrier between four coincident omni's with post processing may be t=
he way to go if your after a smaller rig, or a dipole setup - in the field =
it sounds mono so perhaps not that useful.

The audio at 02:29 =96 03:28 is a Dipole Microphone in the example on my bl=
og:-

http://www.urlme.net/blog/?p=3D1297

The omni's are EM172's and 2 per channel - they fit inside the original Edi=
rol/Roland CS15 microphone.

Circa 2010 vintage.
