Well, for example, load a mono file in Logic and copy it to a second track.
Invert the polarity of the second track, add a compressor to it and use
extreme threshold and attack settings. Enable auto gain. The tracks
won't null and it's not related to latency. Not really an issue
when you using an analog console and outboard gear. That's all I'm saying.

Of course they won't null, they are different tracks. The end result is
the difference between a compressed track and an uncompressed track. If
it nulled out, what would be the point of using compression in the first
place?

What you should get is a track with exaggerated dynamics... that is on
the quiet passages you will have removed more of the original signal
than you will have on the softer passages. What you have done has been
to build an expander.
