Hi Walter--

The mkh-20's in SASS! Of course. Easier for stationary field
applications than A/B.  I'll have to track down that link you posted
with how to order just the SASS housing.

Barred Owl: 3 secs in on
B.SASS.MKH20.mp3
left channel.

Thanks a again for your thoroughness, great tests, should be a
permanent page along with links to the rig pictures,. SASS,.. a great
resource all together.

Are you going to pick up a pair of the Rode NT1A's cardioid
condensers with 5dB inherent noise? Not really suited perfectly for
frog ponds but at $200 each,.. possibly a key addition to the low
noise on a budget site?

Best
Rob D.
