> Multi-channel audio has the dialog track separated. So you can increase the volume of the dialog if you want

Are you talking about the center channel on an X.1 setup or something else? My Denon AVR certainly doesn't have a dedicated setting for dialog, but I can turn up the center channel which yields variable results for improved audio clarity. Note that DVDs and Blurays from 10+ years ago are easily intelligible without any of this futzing.
