Marco and Steven-
Interesting. I have a hunch that a lot of the difference we're
hearing is that the D50 has much more low-end response. The
self-noise and/or frequency response of the mics is so different that
there's no good way to match the volume for comparison without some
embedded sounds for reference. I made an RMS "match" and put them
into a movie with the D50 sample first:

Marco, if you could, take the recorders outside and record some
ambience when you get a chance. The gain can be set to get -12 to -20
peaks or in that range. Again, make sure all filters are off. I'm a
little concerned by what could be lack of bass in the M10, but
another test will tell us more. Thanks! Rob D.
