acceptable differences in mics for stereo

["Paul Jacobson" thebrunswicktwitcher]

Hi All

Just curious what variation in mics is acceptable for stereo
recording, and is it feasible to compensate after the fact?

I ask the question as I have recently bought 2 x AT3032 from diffrent
sources, one of which turns out to be from a old production batch,
while the other purchased from an online source seems to be from a
far more recent run - I'm guessing at 4 years between runs based on
batch codes.

The main issue is with a preamp giving 60dB gain I'm getting a 1.4dB
hotter signal from one mic.

Out of interest what are the batch codes on the "sweet" AT3032's?


cheers
Paul
