It appears that we can't put much faith in the numbers provided by the
equipment manufacturers (surprise, surprise!). If I had the recorder
in front of me, what should I do to measure EIN?  Or the maximum gain
that a recorder's preamp can add to the mic input?  If we could come
up with a test procedure, maybe the members of this group can generate
our own numbers.=20

How did Raimund Specht collect the information about the Marantz
PMD671 on his web page at
http://www.avisoft-saslab.com/tutorial_mic_recorder.htm
I guess I should read the relevant pages at the RANE website, starting
here
http://www.rane.com/note148.html

Sometimes I feel like I'm at a wine tasting when I read reports about
recording gear.  Once we have a way to measure EIN and preamp gain,
how can we measure the "quality" of the preamp output without
resorting to adjectives like "transparent," "airy," "warm," and
"detailed?"=20
