I made adapter cables which reverses the polarity on the analog-in's, so my future recordings will be kosher (though I still can't hear the difference!).
What is the best way to invert the polarity in post?
I'm not sure if a polarity inversion can produce an audible difference (which explains how it went undetected in their production models).
Yes, by all means, spend thousands of dollars, sweat every detail you can control, and then ignore the polarity....
It determines whether the speaker thrusts forward to produce a positive pressure wave, or goes backward. On a symmetric wave, like a sine wave, it probably does not matter. Some sources, horns in particular, tend to produce very asymmetric waves. I don't think those can be reproduced correctly if the polarity is wrong, though I have not done listening tests.
Fortunately it can be easily corrected in post.
