High Fidelity at the Crossroads
101 years ago, the tinfoil cylinder started it all. Within 22 years, its heyday was done, and public support swung to favor the then-new wax-mastered disc. 1948 saw the switch to a slower speed and a finer groove, but the flat disc, traced by a stylus, has held sway for almost 80 years now. Even today, people with multi-speed turntables and a couple of arms (or plug-in cartridges) can reproduce from a single phono unit the earliest or the latest discs merely by the flip of two switches (for speed change and cartridge change). All that is about to come to an end.
