Most of us are goin through very digital stuff for our recordings 99% probably so this could easily elude us even that much more.
I think this vid does a great job of explaining maybe how "tape saturation" may or could have been used on VH1 enhancing the tone. It seems a pretty fair amount of harmonic magic is acheiveable just in the "goin to tape" process-maybe they really jacked Ed up this way for more fluffiness.
This could explain that bit more gain we perceive maybe?? Just "how much?" is there to the tape sat deal in the final product??
School is on. Take a lookity listen to the "saturation" alone in the very beginning of this-watch the initial vid then there will be a link to another vid of the bald dude explaining each function-that's where the goodies are about the saturation Listen also to the end of the first vid demo recording and you will hear some VH "RECORDING MAGIC" if you have the ears to pick it out and keep in mind Ed's quote how the 2" tape just "whomps"

Also explains how "phase reverse" or "inverting" on the echo happens in nature. Bunch of good stuff here
