It takes a while for audio-related technologies to mature. Tubed amplifiers were invented by Lee de Forest in the nineteen-teens, but while there are still some adherents of early high-distortion triode designs, the age of mainstream high-fidelity amplification dawned with higher-power/lower-distortion amplifiers developed by Williamson and McIntosh followed by the Ultralinear take on the Williamson concept. That was 30+ years down the technology-evolution timeline after de Forest.

And when it comes to solid state amplifiers—the usual kind—does anyone prefer the state of the (germanium) art circa early 1960s to modern silicon class-AB designs? I doubt it.

Now, decades into its own development, class-D amplification seems to have sea legs, even in the audiophile world.

"New York is an ugly city, a dirty city," John Steinbeck wrote in 1953. "But there is one thing about it—once you have lived in New York and it has become your home, no place else is good enough." Decades later, the novelist's insight about this appalling, incomparable city still feels true. New Yorkers love to complain about the summers, with their wafting miasma of hot garbage and urine; about the superannuated subway system, which only sometimes resembles a psilocybin trip gone really wrong; about the purgatorial agony of finding an apartment; about the affronts of existing shoulder-to-shoulder with the stupendously rich. . .

What I'm getting around to saying is that easily the best part of living here is the people. One of them is Jeffrey Catalano, who has been a drummer, painter, DJ, and construction worker and today runs a hi-fi business, High Water Sound, from a loft in a former sail-making factory on Water Street in Manhattan's financial district.

In 1928, Swiss engineer and inventor Jean-Léon Reutter created a clock that could run for years without human interaction or any type of external power source. The Atmos Clock required no AC power, batteries, solar panels, or hand-winding. It was able to wind itself by leveraging subtle changes in atmospheric pressure and temperature.

The design was so energy efficient that a single degree of temperature change provided enough power for two days of operation; it would take an incredible 60 million Atmos clocks to equal the power demands of a single 15W light bulb. 95 years later, the Atmos Clock is still being manufactured in Switzerland by Jaeger-LeCoultre, but like most high-precision, Swiss-made instruments, it isn't cheap. Prices start around $7500.

At least I didn't get arrested is a helluva way to begin a story, but then I never expected the FBI to question me about my online record shopping, viewing it as cover for potentially "Conspiring to Provide Material Support" to an international terrorist organization. "We need some information from you," the email said. "We've also temporarily limited certain features in your PayPal account."
