Both mics are likely to have similar noise performance with 19->22
dB(A) self noise and good output (sensitivity). If you are
interested in DIY, lower noise, omni mics (which many nature
recordists are!), the tip that Klas dropped about the tweaking the
EM-23 with the amp he suggests might be "must look into stuff."
13dB(A) self noise is a considerable drop in noise compared to
22dB(A). I think the EM-23 with that amp is ~10mV/Pa sensitivity.
