This recording has tremendous physical presence in terms of 
placement, voice and eventfulness. Over monitor speakers too. 
Listened to it many times. How far are the frogs from the mics? They 
seem as close as 4-8', but if they're like Grays, they really put it 
out and could be much further. I've never heard these guys before -- 
fascinating-- the similarities yet pronounced differences with the 

Yes, we could be in for some rethinking about what we hope an 
outboard pre can do regarding noise.  Thanks to Klas' patient 
insistence and Dan's generosity, it seems there are some ways to use 
truly low noise mics with consumer MD/DAT built in mic pres. In the 
testing I've done, the NH900 with the Denecke phantom power supply is 
astonishing clean with NT1-A's (when I can get it working, more 
later).  For those who like low-profile, binaural rigs, we really 
need affordable low noise, high sensitivity omnis (~10 dBA or less 
and >20 mV/Pa!) and they can be phantom powered. Omnis have a number 
of advantages. My paired, "wide" cardioid NT1-A's seem to only cover 
about 120 degrees uniformly. Gianni may look into the multi-pattern, 
Rode NT2000's-- large and about $400 each, but very flexible if they 
perform well in this combination. Only testing will tell.  Anyway, 
its an exciting possibility because many more people could get into 
gear that is well suited for nature/ambient/field recording.

  We can definitely work something out. I'll contact you off list, Aaron. Rob D.
