I would like to experiment with binaural recording of acoustic/folk music.
I will be recording in a reasonably quiet room with no PA.

Does anyone have any comments on the noise level, and sound quality/clarity of
various lav mic? I'm looking at (in order of increasing price...):

AT899, Countryman B3, Senn MKE2-GOLD, DPA 4060

I know these are all good for voice, but I'm wondering how they compare for
music recording.

I've got prices (without phantom power adapter) of roughly $100 for the AT899
(supposedly on sale), $200 for the Countryman and Sennheiser, and $350-400 for
the DPA. Should I expect peformance on par with these prices? Some people
told me that the Sennheiser sounds better than the Countryman B3. Is that
true? How much difference do people report between the Sennheiser and the
DPA?

Thanks for any help,
Richard
