Back in the '50s, Cesare Sanavio, then a new electronics graduate with a specialty in output transformers for tube amplifiers, began his career in radio and television, traveling to various locations outside his native Italy to apply his expertise. Eventually he settled in Paraguay and started designing tubed sound systems for public installations, teaching his son Luciano the art. A few years later, Sanavio and his family returned to Italy. There, he worked as a consultant to several hi-fi companies. Finally, in 1994, drawing on decades of accumulated knowledge of tube-amplifier design and manufacturing, and a particular focus on output transformers of the highest quality, Cesare Sanavio and his two sons, Luciano and Lorenzo, formed Mastersound.
When Cesare Sanavio died, Lorenzo and Luciano continued operations. In 2015, the company re-formed, with some new international business connections and a new CEO, Antonio Ferro. The company's new headquarters is in Arcugnano, a small town in the province of Vicenza. It employs six people, four in production and two in the office. Luciano is now the company's lead designer and production manager, a role previously held by Lorenzo, who has retired from such duties but remains a co-owner of the business.
Today, Mastersound's stated goal is to produce tube amplifiers of the highest quality available on the market. To this end, the company hand-builds each amplifier in its own laboratory, "one by one, with extreme care," their "Made in Italy" webpage asserts, "using the best components" and manufacturing techniques. Mastersound output transformers are hand-wound on a mechanical winding machine in a secret, closely guarded process the company claims makes them "unique in the world."

German kitchens, Japanese amps, and Afropop gems
BRILLIANT CORNERS - I have a day job at a museum. One of my favorite things about working there is taking the elevator from my office down to one of the floors open to the public; I walk into the galleries through a discreet panel in the wall. This makes me feel like I'm in one of those horror-movie manors with a tunnel concealed behind a bookshelf. Sometimes I startle people, which I kind of enjoy.
EDITOR'S PICK - RECORDING OF THE MONTH
The record business was awash in money and power. Vinyl LPs were still five bucks, and while the pressings could be suspect, the music-buying public still snapped them up en masse.
The Butthole Surfers wipe out
REVINYLIZATION - Music's lunatic fringe drifts further out every hour. As it should. In this century, with computers playing an ever-larger role, music continues to fragment and become infinitely more varied. This splintering is either the essence of what keeps it relevant as an art form or something profoundly disturbing, to be hated and feared.
You're only lonely
AURAL ROBERT - The least surprising story in music today is the inevitable passing of irreplaceable talent. Tenor saxophonist Benny Golson died at age 95 the day I finished this salute to another fallen star, Southern California singer/songwriter John David \"JD\" Souther.
PS Audio Aspen FR5 - LOUDSPEAKER
I remember the first PS Audio product: a simple phono stage. It was so simple - a passive RIAA eq filter flanked by a pair of primitive op-amps - that when the schematic was made public, I built one myself; I was in the midst of my DIY years. I thought it was, to use a word from that time, nifty.
TEAC UD-701N - STREAMING PREAMP, D/A CONVERTER
In Gramophone Dreams #88, I described the sound of TEAC's VRDS-701T CD transport as \"dense and precise in a way I had never previously heard from digital.\" I went on to explain, \"by dense, I mean there was a tangible corporeality effected by seemingly infinite quantities of small, tightly packed molecules of musical information.\"
Sonus faber Sonetto V G2 - LOUDSPEAKER
Here's a hard truth: A written review of a full-sized speaker any speaker, really-is, at best, semi-useful. We all listen differently, we have different musical tastes, our system electronics are different, and our listening rooms vary a lot. You will gain a general picture of a speaker's capabilities and foibles from John Atkinson's measurements, and I can tell you how the speakers sound to me, in my room. But that's it. You need to hear them for yourself before making a buying decision. The best I can do is tell you how my music brain felt when the speakers were in my house and making music.
STEREOPHILE'S 33RD ANNUAL - PRODUCT OF THE YEAR AWARD 2024
When Stereophile's Product of the Year Awards were first published, in 1992, we decided that unlike some other publications and their awards schemes, we would keep the number of categories to a minimum. That way, we would avoid what the late Art Dudley once described as the \"every child in the class gets a prize\" syndrome.
Moon 861 - POWER AMPLIFIER
It is unusual to begin a review with a detailed discussion of setup. But setup protocol for the Moon 861 power amplifier ($22,000 each), the top-level amplifier in the North Collection from Moon, which I reviewed bridged in mono, proved crucial to its sound.
Mobile Fidelity, PrimaLuna, and First Watt redux
GRAMOPHONE DREAMS - It's important for readers to remember that I've spent my adult life as an artist and mechanic. Making things. Working as a tradesperson during the day then at an easel or workbench at night.
