Well, I'm of two opinions on that.

While I think it's great we have a complete mono mix to work with at all, and that it sounds as good as it does, I think its audio quality really pales compared to our Laserdisc-sourced tracks. I find it a little jarring to watch some of our preservations with stunning video and mediocre audio, so I don't give the mono mix as much love as it deserves.

That said, the first time I heard the mono mix "theatrically", it was via a tiny plastic speaker hanging on the window of my parents' car. So to be honest, we'd really have to make it sound a whole lot worse to get "theatrical quality" ;)
