As Eric says, though, this isn't much different from what
happens with phono cartridge amplifiers. In fact, one _might_ even say
that all that is happening is that the implicit eq in electro-mechanical

domain.
That's correct, but there is a practical difference (pun not intended).
For the EM cartridge, or the ribbon mic, the difference operation is
done in the physical domain and the problem of unmatched gains before
the difference operation does not arise. And that is not just a matter
of calibration but also of stability. If one mic becomes 0.1 dB more
sensitive than the other (because of e.g. a temperature difference),
and you amplify by 40 dB, then the error has the same magnitude as the
wanted signal. Things get much worse again for higher orders.
