Well you know I just have mention....
You can read about a comparison I did on the Studio Projects C3 vs
the sE Electronics SE2200-A on my web-site if you'd like (Studio Stuff page).
The C3 is the next step up from the C1 and is a 3 pattern large diaphragm mic.
The 2200-A has only a cardioid pattern.
The C3 has a lot of sibilance/hi-end where the 2200-A is a little more flat across the spectrum with a little less bump in the highs but enough to catch a little air as they say.
C3 is $269 street.
2200-A is about $299 street.
2200-A has a much nicer shockmount and has a better overall quality feel in my opinion.
Unfortunately the old model sE Electronics have gained a not so good notoriety due to build problems and reliability issues. In fact, as I have read, they used to be built where Studio Projects, MXL, ADK, and other mics are currently built (OEM?).
sE now has it's own factory and now oversees all phases of their manufacturing processes from start to finish. Yada Yada Yada....
