An acoustics lab that built itself an amplifier.

FM Acoustics did not set out to make hi-fi. According to the company’s own history, it was founded in May 1973 by Manuel Huber as a small laboratory for research and development, hired by clients for acoustic and vibration analyses. The company says it held a number of patents in those years and lists early loudspeaker work — a non-resonant horn, a forced-air-cooled bass driver and the cooling of voice coils inside the magnet gap — some of which, it says, other manufacturers later copied. We give those as its claims; we could not check the patents one by one.

The amplifier came out of a practical problem. The company says the professional amplifier it used for room analysis kept destroying expensive reference drivers by putting out full DC voltage, so the lab designed a sturdier one, with protection circuits and better cooling, for its own use. Only four were built. One, an FM 800A, was lent to musician friends whose amplifier had failed; they refused to give it back. Ten more were made for other musicians, then requests came from neighbouring countries and from overseas, and when a telex arrived ordering several hundred amplifiers, the company says, it decided to invest in a small manufacturing facility.

The FM 800A, the company says, went into hundreds of concert halls, studios and opera houses. That professional root still shows: FM Acoustics sells a professional line of microphone preamplifiers, crossovers and power amplifiers that it says are always adapted to each client’s specification.

The legal entity today is FM Acoustics Ltd, a Swiss Aktiengesellschaft registered in Egg, in the canton of Zurich, according to the federal company index Zefix. Its registered purpose is the manufacture of and trade in recording-studio equipment, loudspeakers and related products. The company’s website gives the same town, Egg bei Zürich, east of the lake.

From the studio to the listening room.

Home listeners came to FM Acoustics through the studio. The company says musicians and producers began taking FM 600A and FM 800A amplifiers home because they wanted the sound they heard at work, and that its first product designed for domestic use was the FM 212, a preamplifier for moving-coil cartridges. Line stages, preamplifiers and linear-phase electronic crossovers followed.

Its best-known domestic idea is the phono linearizer. The company says it launched the FM 222 Phono Linearizer at the height of the compact disc, when much of the industry had written off the LP. Instead of a single fixed playback curve, the unit offers continuously variable de-emphasis, so that the listener can match the different equalisation curves record companies used when mastering older records. Today’s FM 123 and FM 223 PhonoMaster add circuits to reduce clicks and crackle in real time; the company calls the de-crackle work its longest research project, begun in the early 1980s. It also makes “Harmonic Linearizers,” the FM 133 and FM 233.

At the top of the range is the Resolution Series, whose current flagship amplifier is the FM 1811-MKII. The company describes a dual-chassis design with a hand-assembled 21-kilogram transformer and says the amplifier needs a dedicated mains supply. There is also a loudspeaker system, the Inspiration System, and a dedicated subwoofer, the TS-1, which the company calls the “True Sub.”

Independent coverage of the brand is thin in the sources we could reach, but it confirms the scale of the prices. Reporting from the AXPONA show in Chicago in May 2014, Part-Time Audiophile described FM Acoustics as “uber boutique stuff,” with a Resolution Series 245 preamplifier at about $30,000 and a pair of Resolution Series 115 monoblock amplifiers at $130,000. The company’s website hosts reports from French, Italian, Korean and Chinese-language magazines, which we have not read in full.

The brand still appears at shows. In October 2026 the company said it would exhibit at the Milan hi-fi show at the Quark Hotel, recalling a 1996 event there at which, it says, five classical musicians were recorded live and the recordings replayed through its large Inspiration System.

Design and documentation.

Europe has a layer of very small makers whose products are built in small numbers and sold at very high prices. Five of the seven brands in this round are Swiss; the other two are Greek.

The Swiss five are spread across the country. The Swiss commercial register, Zefix, lists Stenheim Suisse SA with its seat in Vétroz, in the canton of Valais; FM Acoustics Ltd in Egg, near Zurich; and Daniel Hertz SA, the company associated with the audio engineer Mark Levinson, in Milvignes, in the canton of Neuchâtel. Boenicke Audio is registered in Basel as a sole proprietorship, and its website is signed by Sven Boenicke.

Lumen White, a loudspeaker maker that dates its speakers to 1999, now gives a contact address in Lucerne; in 2017 its website named a London address for its group and Lucerne for research and development.

The two Greek makers are both in Attica. Ypsilon Electronics says it was formed in 1995 by two sound engineers and gives an address in Paiania, east of Athens; Ideon Audio, founded in 2016, gives an address in Nea Filadelfia.

What links them is scale and price rather than place. At the top of these ranges prices run high — Part-Time Audiophile listed Ideon’s Absolute ε DAC at $47,000 in 2024 — and some runs are tiny: Ideon says its 2026 Ayazi anniversary edition is limited to 20.

This guide sets out what can be checked about each brand — who founded it, who owns it, and what it says about where its products are made — and marks clearly what rests only on the company’s own word.

Made to order, sold at a net price.

FM Acoustics presents itself as a workshop rather than a factory. All products, it says, are made to order; every component is selected “by hand ear and eye,” every circuit board is hand-soldered, and a line stage can take three to five days of fine-tuning. Its production page walks through transistor and potentiometer selection, hand soldering, calibration, burn-in and vibration testing, and the flagship amplifier’s page says each unit is “crafted by hand to special order at FM ACOUSTICS facilities in Switzerland,” with three engineers testing every one. Those are the company’s claims; we did not visit, and the company says visits and factory tours are not possible.

How it sells is as distinctive as how it builds. FM Acoustics describes itself as a production company that does not demonstrate, advise or sell directly: buyers go through appointed distributors. Under what it calls a net price policy, distributors do not give discounts, and the company quotes prices only in Swiss francs, warning that figures found elsewhere online may be out of date or falsified. Registered owners who scan a QR code on a unit’s hologram sticker get a five-year warranty, the company says.

It is also unusually direct about its online presence. Its website says FM Acoustics keeps no accounts on Facebook, Instagram, LinkedIn, X or similar channels, that any presence there is not from the company, and that information gathered by AI tools should be checked too — a fair warning for anyone researching the brand, this guide included.

The company calls itself independent, self-funded and family-owned. The Swiss commercial register shows a change on its board in 2016, when one board member named Huber left and another joined; we found no outside investors in the sources we checked, but the shareholding itself is not public.

For a design guide, FM Acoustics shows a brand built on refusal: no showroom visits, no discounts, no social media and no restyling for fashion. Compare Nagra, another Swiss maker with roots in professional recording, and CH Precision. For this guide we use black, brushed silver and a muted gold with a sans, an unofficial interpretation; no product or logo is reproduced.
