Heh, It's probably my bad Karma, Max.
I did notice the 25 DB?, so I haven't been in a hurry ;)
When I bought the Sony mic it was a few years before I became at all
serious about recording. It was an improvement over something even cheaper.
I was making casual recordings of gigs I played, so much of the self-noise
would have been masked by cymbals and the background noise of the crowd.
As I think back, I have to admit I'm a wimp. Although my first recordings
go back to a Webcor wire recorder, it wasn't until half decent audio
interfaces for computers became affordable that I could get results that I
could stand, and thereafter develop more than a cursory interest in
recording.
Some of the most useful material I've seen on comparing mic specs came on
links I found in this group. It was a great help to get a feel for how the
relationship between sensitivity and self-noise affect noise performance of
a mic/pre combination.

I also find this site very useful:

You need to set up an account (free), but I haven't received any new, or
more spam than usual after signing up.
Take a look at the sensitivity vs self-noise of some of the >$2K
Sennheiser's that get mentioned on this list. Then take a Valium & lay down
for a while.
A little OT:
One source of inexpensive and quiet mics that seldom gets mentioned here is
CAD. I have 3 M-179's and a Pair of e300=B2's. One caveat with these is tha=
t
they're pretty greedy on phantom power, drawing around 8ma/ea, which will
probably exceed what your portable recorder will supply. They are
multi-pattern though (179's are inf variable), and great for MS recording.
I got some decent MS stuff with a pair of 179's on my Tascam HDP2, before I
realized I might be toasting the phantom supply. Now I'm a bit timid about
trying it again.
Rode is in the same league for noise, and probably less greedy but on some
models they seem a little queasy about actually stating current draw (just
listing as P48).
I think my next move is to get some Primo EM172's (lots of stuff here on
these) and warm up the soldering iron.
Cheers,
Keith
