Dragon Ball:
As far as I'm concerned, the audio tapes for Dragon Ball are trashed. A friend of mine told me Toei did not get rid of them, just did not release them. I don't believe it, as it's not consistent with the the rest of their actions in the 80's and 90's regarding audio tapes. Stereo Audio for the Japanese version is only available on raw VHS/Betmax/Video8 tapes carried by enthusiasts and fansubs sold between the early 1990's and early 2000's.
Dragon Ball Z:
There is no doubt in anyone's mind that the Stereo Audio for the 291 episode Dragon Ball Z series is gone forever. Again, they can only be heard on raw TV tapes or copied fansubs.


Dragon Ball GT:
The Stereo Audio tapes do in fact exist. Not put on any commercial release, but can be heard when airing on Animax in Japan.

Now here's where I'm confused. The 17 Dragon Ball movies produced between 1986 and 1995. All commercial releases have Mono Audio, but these are movies, and are obviously cared for more than the episodes, like with the better animation and such, and as we've seen in the past, Toei has been pretty lazy with how they handle audio.
My question to all of you is, do any of you know of any medium that could have Stereo Japanese Audio for the films, like bootlegs or any Television networks. Right now, I'm just to collect as much information as I can.
