The ability to fine-tune a vinyl playback system is part of what makes it possible to combine an archaic technology with modern thinking and materials to create musical magic, and take listeners to new heights of ecstatic musical pleasure. It's why so many young people are tuning in to vinyl, and helps explain why just today, as I write this, it was announced in the UK that, for the first time, revenues from sales of vinyl exceeded those from downloads.

As Vilray Bolles marched down Manhattan's Second Avenue on a rainy afternoon late in 2014, participating in a demonstration against police brutality, he slipped on the wet pavement, fell hard on his right hand, and broke his pinky. For a guitarist, a broken finger can be a major, if not catastrophic, setback. But the gods were smiling on Bolles. He was, in fact, a lapsed guitarist, having all but abandoned hopes of a musical career, and the universe was giving him a nudge, not just back into music but into a collaboration with Rachael Price, one of contemporary pop's great vocalists, who, when she isn't singing cabaret jazz with Bolles, fronts the headlining rock band Lake Street Dive.

You won't see many Apple products in these pages, and for good reason. As Stereophile Editor Jim Austin wrote to me recently in an email, "Apple may have the best acoustic-design facilities in the world, but its products are designed by engineers who don't seem to respect perfectionist sound—which is appropriate for a company that aims for the vast middle of the bell curve." Has that changed?

Like many other industries, audio has its power couples: behind-the-scenes movers-and-shakers who shape the trajectory of the industry and who also happen to be, well, together. Angela Cardas and Josh Meredith of Cardas Audio come to mind, as do Dave and Carol Clark of Positive Feedback, Eli and Ofra Gershman of Gershman Acoustics, Luke Manley and Bea Lam of VTL, Carl and Marilyn Marchisotto of Nola Speakers, Edwin and Gabi van der Kley-Rynveld of Siltech and Crystal Cable. George and Carolyn Counnas of Zesto Audio are a hi-fi power couple I'm especially fond of; I'm always happy to see them at shows, catch up with them on the phone, or exchange emails with them. Their sweet demeanor and good vibrations always lift my spirits.

George designs Zesto's preamplifiers, power amplifiers, phono stages, and step-up transformers, while Carolyn, a talented fine-art painter, gives Zesto's products their unique organic curves...

The Amtrak Empire service snakes north along the Hudson River before reaching Albany, where it pitches sharply to the west, eventually winding up in Niagara Falls. In November I rode it—the Amtrak Empire service, not Niagara Falls—from New York City to the town of Hudson, New York. On my left, the sun beat down on the river's expanse while an occasional sailboat flashed by. Above the water, the undulating domes of the Catskills, with their fading yellow and red streaks, looked like the work of an unsuccessful colorist at a busy hair salon.

I was traveling upstate to visit Rob Kalin, a founder and former CEO of the online craft marketplace Etsy and proprietor of a newish speaker company called A for Ara.
