Actually, Bell Labs was located in Murray Hill, NJ. I used to go to their sound proof room when I was a kid. A million dollars does not buy you great sound. Have you been to a reviewers system lately? LOL
The trick, pioneered in the early 1930s by engineers working at Bell Labs in New York and Abbey Road Studios in London, was in the two channels of sound. Recorded from separate microphones and played back through separate speakers, they could simulate the swirling warmth and depth of life.
