Living Sounds Audio Discovery Warp 1 - POWER AMPLIFIER
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.

Miyajima Laboratory Wo-1 - PREAMPLIFIER
A phenomenon formerly unique to Japan, which in recent years has been emulated in cities around the world, is the jazz café (known as jazz kissa in Japan), where salarymen can find respite from their hectic lives, loosen their ties, and enjoy hi-fi jazz over coffee or a drink.'

Antipodes Oladra - SERVER/STREAMER/RECLOCKER
Servers, servers, servers. How we who embrace digital hi-fi love them for their potential to make files and streams sound better (more alive, vital, musical, moving, transparent) than music served from a computer.

HiFi Rose RS520 - STREAMING INTEGRATED AMPLIFIER
My first car was a decrepit, mustard-yellow Peugeot 304 with a navy hood. The blue hue wasn't a fashion statement; after an accident, the previous owner had gone to a salvage yard where only a blue replacement could be procured.

SPIN DOCTOR - Swiss precision
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.

BRILLIANT CORNERS - Come Hell or High Water
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.

GRAMOPHONE DREAMS - An affordable purist amplifier with punch
It was a cold March-in-Brooklyn morning. Clouds had been shedding wintery mix since daybreak. By 9am, birds were flash-mobbing my window, demanding suet. But I was frozen-unable to pull my mind loose from the grave flowings of American composer Ned Rorem's Book of Hours, as performed by Les Connivences Sonores on the album Musikalische Perlen (24/48 FLAC, Ars Produktion/Qobuz). The sounds in my room were sensuous and mesmerizing, and I needed to float in their mysterious energy as long as I could.

TAD CE1TX - LOUDSPEAKER
The most money I've ever spent on a pair of loudspeakers was back in the early 1990s, when I bought a pair of used TAD TH-4001 wooden horns and their associated TD-4001 compression drivers.

GRAMOPHONE DREAMS - Stick vs automatic
I wish that all who love LP playback as much as I do could hear a Thorens TD 124 or Garrard 301 or EMT 930 in their systems, but those products are subject to the vagaries of supply and demand: They are rare and pricey.—ART DUDLEY

Nessie Vinylcleaner ProPlus+, RECORD CLEANING MACHINE
I ’m a music lover first, not the most Type A of audiophiles. Sure, I clean my records, but I’m not obsessive about keeping them immaculate like my audiophile father is;1 he cleans each record ultrasonically before it lands on his turntable platter, writing the date of each record’s last bath and which cleaning machine he used on the outside of a fresh plastic inner sleeve before sliding the LP back inside.
