Larry, here are the pros and cons of
the Beta 87a compared to a good
large diaphram condenser like the Studio Projects C1.
Pro-
1) Very tight cardiod pattern and low sensitivity make it useful for close
miking if your room doesn't sound that good to begin with.
2) If your doing a live recording with a band the same applies.
Con-
1) Not as much vocal detail as a good large diaphram condenser.
2) Not as much of a "hot output" as a LD condenser, therefore it
needs higher gain on a mic pre or mixer=more noise.
3) Lower signal to noise ratio than a good LD condenser=more noise.
4) High end can sound harsh on some singers, the 87a sounds better
when run through a decent tube mic pre and/or photo-optical
compressor like a Joe Meek IMHO.

P.S. I think the 87a sounds "good" it's just that typically a LD condenser
will sound better for most singers.
