 of my recorders is an Olympus LS-11, which I primarily use with a PBBA bas=
ed on EM172 microphone capsules. The LS-11 PIP input is not ideal for the E=
M172 due to average input impedance (2K Ohms), but it does pretty well. The=
 Sony PCM-M10 (and the much more
 expensive PCM-D100) work very well, due to a combination of low EIN and hi=
gh input impedance (22K Ohms). I don't own either Sony but have tested and =
verified this on the PCM-M10.</span>

I am concerned that my LS-11 is getting old and will not last forever, and =
I have no backup other than a Sony MZRH1 Minidisc recorder, which has an ex=

Among current-production handheld recorders, which has the best PIP input, =
both in terms of preamp noise and impedance to work well with EM172 capsule=
s (which have an impedance of 2.4K Ohms)? PIP input specs are not often pub=
lished by the manufacturers, so
 this information is hard to find. Raimund's information on<span class=3D"A=
pple-converted-space">&nbsp;</span><a href=3D"http://www.avisoft.com/record=
er-tests" class=3D"">http://www.avisoft.com/recorder-tests</a><span class=
=3D"Apple-converted-space">&nbsp;</span>appears to be
 up to date, and is very helpful, but does not always clarify (as in the ca=
se of the Tascam DR-100 mk3) whether the measurements are for the XLR input=
, the PIP input, or both. The reference manual for the DR-100 mk3 specifies=
 50K Ohms for the input impedance.
 If Raimund's EIN of -126 dBu applies to the PIP input, then the DR-100 MK3=
 looks to be the best of the bunch, equal to the PCM-D100 at less than half=
 the cost.</div>

So, which current-production, mid-priced, handheld recorders have good PIP =
