Thank you for posting the nice sample, John.
After some serious comparison studies with my AT3032s and AT4022s
earlier this summer, I'm beginning to strongly prefer the trusty old
WL-183s almost anywhere that doesn't require ultimate low noise specs,
which I'm also beginning to realize is almost everywhere if you're
careful.
Question for you, Mike: You mentioned somewhere a while back that the
Primo 172 capsules showed an increase in sensitivity with higher PIP
voltages (like from a 9v battery box vs the 3v PIP from the Sony D50.
I don't know how to make those measurements, but my experience seemed
to bear that out; they seemed much more stable. So my question is...
do you know if this is also true with the 183/391s? Anything to be
gained by running these Shure capsules off a 9v battery box?
Thanks in advance,
Curt
