Greg,

I will test the SASS with mic capsules at both locations. I don't
have any birdsong though, only atmosphere. I doubt that it will make
a difference. Can you send me a simple drawing? (max 200k)

The website is not public and was never meant to be.

Comparing / evaluating: If I need to describe the SSM by saying that
"it is less forward looking than the SASS and less side reaching out,
but .... e.t.c."
Then I also need to know by own experiments that it is correct.
If I need only need selling arguments for the SSM, weight and size is
unbeatable.

Can you describe "glitches"?

Klas
