Spent some time with my R183B/CS122's this weekend. So far, I've
found the low end characteristics to be very compatible with natural
settings. The bass is smoothly contoured down to ~40Hz. I would not
favor using mkh-20 in this regard.

This response is extraordinarily common with lavaliere mount mics to
help offset accentuated nasal tones. Most Large condenser omnis
exhibit it too. I prefer it in omnis.
Curiously, the noise of the Plug-In-Power R183B/CS122/ is more
"sennheiser-like" than any other plug in power mic I've used with
~80% of it concentrated above 4K with concentrated bands around 8.3K
just like the MKH-20's, 30s & 40's. The fact that we are even
discussing mics with 22dBA and 10dBA self noise at ther same time is
significant.
When I listen to the comparison of the R183B/CS122's, the NT-4 and
the WM61a's, the later two are in the same realm and the R183B/CS122
produces a huge jump in transparency without significant loss of
tonal response. The costs are $200, $400 and $14 respectively.
I'm sure everyone recalls the many discussions about low
noise=phantom mics=preamps= $$$$. This changes that. For $480
(NH900/R183B) I can have a very nice second 16 bit unit that is very
close in quality to what I got with my MBHO 603/mp2/D7 $3000 kit. Two
weeks ago I was recommending the NT-4 as the best deal for the bucks
for MD use, this changes that.
And they are great for use in a dish too. How about an opposing pair
for a shotgun or little 5.1 arrays? Very flexible mics.
I'm surpised we are committing any time downplaying the importance of
these mics entering our arsenal. Cheers to Dan (and Rudy who was
right in there with the first experiments) !
