Thanks for the pointers, Uh oh, I think I feel some new desires swelling up=
.

To my listening, the mkh 80/80 M-S recording:
http://loscan.home.mindspring.com/S.MS.MKH80-80.mp3

has a great deal more spatial appeal than that made with the  mkh 30/40:

http://loscan.home.mindspring.com/S.MS.MKH30-40.mp3

The MKH80/80 MS has more tone simplification in the lower mids
(harmonic drones). Even though there seem to be two frogs around
10-11 o'clock in the 80/80 recording and a wide spread pair before
the 30/40, there's much more instantaneous DEPTH throughout the field
with 80/80 recording. The pitches of the chorus frogs seem also less
hammered with the 80/80 too.
  I'm surprised there's that much additional hiss from the mkh 30/40.
Is the noise performance of the 80/80 consistently this much better?

I don't need another test, but if you do make one, I'd enjoy hearing
all of the bottom end. The lowest tones set the table for the upper
harmonics.

The difference/improvements I can hear between these two rigs are exciting!

I can't generalize about what nature recording is for a hypothetical
buyer.  Again, I personally would not buy another mkh 30-40 as long
as there are other, much more affordable options like the NT1A or
Nt1A/2A MS out there. The Rodes are larger, clunky mics and not at
all well suited to some people's styles. I'm even more convinced
after listening to your samples.

I feel the MKH line deserves most the good reputation it enjoys.  We,
as consumers, can also enjoy the new approaches mic makers are coming
up with or be happy with what we've got.  I feel that what I can get
out of a pair of NT1A's can be closer the qualities I like in your
mkh80/80 sample than what I can coax out of my 30/40.  I don't feel
mic manufacturers know the way things sound, and I wish they
expressed more interest in getting people to listen to things
carefully like we try to do. This predicament exists before the
engineers and designers and machinists confront the considerable
challenges involved with their crafts. Microphones, portable phantom
power supplies, speakers, etc, not excepted.  Rob D.
