Since the 1980s, I've been asking every speaker designer I meet, "What amplifier do you recommend using with your speakers?" Annoyingly, they always say, "My speakers are easy to drive. Any amp will do." Whereupon I'd whine, "Aww, come on man, don't feed me that. What amp did you use when you were designing the speaker?" The closest any manufacturer came to providing a real answer was Wendell Diller of Magnepan, who, when I reviewed his .7 quasi-ribbon speaker, said, "We used an amp of our own design. It's not for sale. But any amp that doubles its power into 4 ohms will be fine." Wendell's answer helped me choose effective amplification and feel more confident about my conclusions.

Unlike loudspeaker manufacturers, headphone manufacturers know that which amp a reviewer uses could make or break a review of their product. So, wisely, they seem grateful when I ask for guidance.

It turns out that PVC, or polyvinyl chloride—the stuff used to make Starbucks gift cards, imitation leather wallets, inflatable pool unicorns, the pipes under your sink, and Billy Idol's pants—is also the main ingredient in phonograph records. And today we're living in the silver age of PVC. Not the golden age, since records are no longer the dominant medium for recorded music, but these days we're lucky to again have access to a remarkable amount of music stamped on top-quality hot plastic.

Better still, as listeners have become more knowledgeable and demanding, vinyl releases have become more scrupulously sourced, pressed, annotated, and packaged. Many of today's records show an unprecedented level of care and transparency about their production—and sound terrific to boot.

Several traditional hi-fi dealerships have shuttered in recent years: NYC's Lyric Hi-Fi and Chicago's Audio Consultants are prominent examples. A few new brick-and-mortar shops have opened, but it's rare to see a next-generation owner breathe new life into a long-established dealership. Christopher Brewer (above) is doing exactly that with New England Hi-Fi.

We started issuing recordings on the Stereophile label at the end of the 1980s, both to make available some of test tracks that we were using in our reviews and to enable readers to have access to recordings where the provenance was fully documented. That way the "Circle of Confusion" that Bob Katz discussed on the Stereophile website in 2017, where the sound quality of an audio component couldn't be judged using a recording with unknown sound quality potential, could be avoided. As Bob wrote, "How can any reviewer make a judgment about a transducer without knowing what a recording is supposed to sound like?"
