Thanks for taking time to make a sample recording for us, Raimund. I
have some initial observations about the M10's built-in mics.
I was able to lessen the over-stated center of the stereo field by
stacking/adjusting two M-S plugs and then, with EQ inserted between
the M-S plugs, attenuate some lower-mid of the center and reduce some
of the high frequency emphasis and graininess on the sides. Here's a
before-and-after QuickTime movie for the curious:

The M10's built-in mics definitely have more promise and application
than the built-in mics in the Zoom H2 for distant subjects. I did
encounter some of the bumps and peaks in frequency response that
Sony's plot suggests, but the overall tonal balance can become pretty
pleasant after some EQ.
Sony's self-noise rating of 17dB(A) seems about right. I would
characterize the noise as fairly sharp with quite a few narrow peaks
between 4KHz and 7KHz. I found this part of the spectrum too
aggressive to leave as-is. There's some emphasized presence in the
upper mid-range which enhances the spatiality a bit. I didn't detect
a significant amount of noise at the lower end of the spectrum as we
encountered with the LS-10.
The movie only shows the first of the two M-S plugs used. The 2nd M-S
plug is set for M-S to L-R and both of the slider settings are at
unity, 0dB. Rob D.
