Confirmation of Dr. Specht's PCM-M10 noise test results comes in the form o=
f testing by Leonard Lombardo, mic builder and owner of Sonic Studios in Or=
egon USA.
Leonard has tested many small digital recorders for use with his line of mi=
cs and portable amplifiers. Preliminary results for the PCM-M10 were poste=
d recently on the Tapers Section forums, where Leonard posts with the name =
"guysonic."

There are three graphs in this post. The first shows results using the Edi=
rol R-09HR. The second and third are of the PCM-M10 under similar test cir=
cumstances. Eyeballing the graphs, it appears that measurements of the PCM=
-M10's mic input noise stay below -120 dBu as low as 150 Hz. when the Plug-=
In Power is turned off. With PIP turned on, the noise level rises a little=
sooner.
I'll pass on the link to Leonard's discussion of the results when he comple=
tes his write up of the PCM-M10 tests.
