I know what you mean and I noted this many years ago. That is why I never
want to talk about "input sensitivity" and all this. It doesn't say much.
Perhaps in 30% of all cases, it is the combination that work or does not
work and this is especially true with plug-in-power.
The Electret IC 2sk1227 works very well with all plug-in-power inputs,
except the recent Sharp ones. Last year, Sharp started to use a current
limiter to produce the plug-in-power, and it can't provide enough current
for the IC.
Which means that someone buying a Telinga EM23 to use with his Sharp will
get very disappointed and blame the Telinga...?
It is only us naturesound recordists who deal with this problem seriously.=

The others don't even bother much.
