The modified SASS forms the wide/close end of my mic assortment. If I
want to pick up a wide area and it's right close in front of me, I'll
nearly always start with the SASS/MKH-20.
I view my mic setups as being various coverage of stereo spaces. A lot
like various camera lenses cover different widths of scene. But with
mics it's 2d at least, with depth of scene and closeness of scene
entering in too.

DAT is virtually dead. The mechanisms are not being made anymore, and
they are using up old stock. And there is only one factory still making
tape.

That's the trick, the only real test is to get out there and record.
Everything else is guesses.

Rich Peet is the person to ask about these. The version of a while back
was using Panasonic capsules, so high on self noise for quality
recording. Done with good mics it looks like a interesting design. I'd
love to experiment with making a MKH mic version.
