Re: (tech talk) The most sensitive small mics

Hi Michiel,

I have to stress that I am a technical amateur.
I just found the sound of the GA-M2 to be in some way superior. Maybe
it's the flat response.
The only time I really made a comparison was when I recorded crickets in
the Everglades, where I found the sound of the GA-M2 to be much clearer.
Still 50 bucks might be worth trying.

So let me know how you decided

Volker
