Are not there limitations in a academy monaural track even if it is capped at the highest possible resolution and bitrate for sound.

Does not optical in general have limitations because the audio is on the print itself?

Nowadays if they wanted to they could reproduce the sound as exactly as heard in the recording studio off the first gen master.

Though Lucas has not done that.

The blu ray is a poor imitation of the original 77 mix in any of its forms.

Then again out of the few films from the 70's i want to own on blu ray like Superman, Star Wars, or star trek none of them have the original 6 track 70mm mix.
