When people went to watch SW in 70mm back in 77'----all they had in their homes were crude mono sounding TV's(and stereo gramaphones for their vinyl's) So they were always going to be blown away by a 6 track magnetic audio presentation in a cinema!!
Nonsense. I wouldn't be surprised if the stereos in people's homes sounded better in 1977 - on average - than they do today. Back then people typically listened to music in high fidelity, whereas today people are accustomed to listening to music that has suffered from the "loudness wars", and/or been squashed into mp3 and listened through earbuds. So one could argue that on average a person visiting a theater in the late 70s is more likely to be able to discern a lack of dynamic range than today's average listener.
"Gramaphones"? The Gramophone company went out of business in the 1930s. My memory of the late 1970s was Macintosh, Thorens, Pioneer, M&K, Klipsch, etc. Quadraphonic surround had been around for nearly 10 years.
