LOL! It's always the other guys fault. Mechanics blame the Engineers, and vice versa. Thanks for the comic relief pancakes.
Then what do you think it is? Do you think it was because they used more audiophile-grade equipment in the '50s? Silvered wires, cables on stilts, dampening stones, and things like that?
Or do you think it's because you had in those early jazz recordings an unparalleled level of talent sharing the room?
I'd like to hear your rebuttal instead of an ad hominem.
