Gramophone Dreams #103: Ortofon MC X40 phono cartridge, Robyatt & Lundahl step-up transformers

My mother Lily Mae was a Lutheran from Norway. She sent me to Jerusalem Evangelical Lutheran School so that I'd become a well-mannered, tea-with-her-friends choirboy, with starched white shirts and a secret penchant for wildness that was nurtured by those free-thinking Catholic girls at the elementary school next to ours. I always think of Mom when I install an Ortofon cartridge because their sound character strikes me as so Scandinavian—like my mother: smart, tall, well-tailored, well-mannered, neat, understated.

Everyone knows I think audio components tend to sound like how they look,…

Re-Tales #60: Matt Alterman's Crescendo Audio Returns to Boulder

Stereophile December 2025, Vol.58 No.12 Re-Tales #60: Matt Alterman's Crescendo Audio Returns to Boulder Julie Mullins A hi-fi dealer's son, Matt Alterman has been in or near the business almost all his life. His dealership, Crescendo Audio, is coming full circle as he opens a new location in Boulder, Colorado, the town where he launched his first store 13 years ago.

Matt's father, Henry Alterman, was the proprietor of Alterman Audio in their hometown of New Orleans. Henry got his start selling gear from his dorm room at Tulane University in the mid-1970s (footnote 1), before "going…

DeVore Fidelity Gibbon Super Nine loudspeaker

I've watched the DeVore Fidelity factory develop from its humble start as an early tenant in the Brooklyn Navy Yard—once a sprawl of crumbling ruins, now a sleek high-tech hub—into a thoroughly professional facility housing a cabinet shop, assembly, and R&D. It is also the legendary Monkeyhaus, where late-night listening sessions and pizza feasts are a tradition.

I've owned several DeVore Fidelity speakers, from the original Gibbon 8 and Super 8 to the Gibbon Nine and the O/93. I currently own the O/96. What unites DeVore speakers—the singular quality that has earned them a devoted…

The Robyatt Audio SUTs
I have known Robin Wyatt since forever. As anyone will tell you, he's always low key, shy, and retiring. Soft spoken. He blends in with the crowd—except for his brightly patterned "yank" shirts by American tailor Robert Graham (footnote 2). Robin is tall, and I am short, so when we meet, I invariably find myself staring at a chest adorned with silks of many colors.

The chief reason I like Robin is that I admire his taste—in shirts, cologne, dogs, and polo ponies, but most especially in audio. In any ABX tournament, I would bet half my bicycles on his…

Blink High End & Matterhorn Audio Group bring Børresen, Thuono, FinkTeam, Linn, HiDiamond, and Audience

The three heavy hitters noted above brought Italian heavy hitter Thuono to Capital Audiofest (CAF), showing the Thuono TH400 turntable ($59,500) for the first time in the US. I've noted these handsome machines at High End Munich; it's great to finally see the brand stateside.

The TH400 includes a 400mm (15.75")-diameter platter supported by "a proportionally designed rotation system," the press release noted. "Both elements of the chassis are composed of a thick layer of aluminum and Nero Marquinia marble and supported by high precision magnetic suspensions. The unusual dimensions of the…
