A mechanical engineer in Yugoslav Slovenia.

Kuzma is a family firm in Kranj, Slovenia, that makes turntables, tonearms and, more recently, cartridges. The company says it was founded by Franc Kuzma and first started production in 1982, when Slovenia was still part of Yugoslavia, and describes his background as a mechanical engineer with experience of working on acoustic transducers. Its own pages give other dates too — its products have been “praised worldwide by the audio community since 1983,” and it has been “studying the theory and practise of analogue playback since 1975” — so we treat 1982 as the start of production, on the company’s word.

The first turntable was called the Stabi, for stability. The company says the original Stabi, made from 1982 to 1986 in solid oak with a smoked-glass lid, was never exported outside the former Yugoslavia, and that it was replaced in 1985 by the Stabi 2, sold abroad simply as the Stabi. The first tonearm was the Stogi, which the company says is Slovenian shorthand for rigidity. Michael Trei of Stereophile, writing in February 2025, records Franc Kuzma’s explanation that stogi means rigid or stiff, and adds in a footnote that the dictionaries he consulted offered “stacks” or “roof” instead; we give the meaning as the company’s.

The arm’s international break came in Britain. Martin Colloms reviewed the Stogi in the November 1985 issue of Hi-Fi News, Trei writes, and found that it could compete with leading British arms such as the Linn Ittok and the Zeta. Trei bought one in London for £250 — about half the US price of an Ittok — and recalls that Franc Kuzma had managed to obtain Van den Hul wiring and Western ball bearings in what was then a communist country, though the arm came packed in crumbly foam with a single sheet of instructions.

From the Stabi Reference to sapphire.

The range grew steadily, by the company’s account. The Stabi Reference of 1990 used a sandwich of aluminium and acrylic for its base, subchassis and platter, with silicone-damped springs and two motors. The minimalist Stabi S was begun in 1997, with the Stogi S unipivot arm a year later, and the larger Stabi XL was first shown at a London hi-fi show in 1999. In 2004 Kuzma introduced the Air Line, a parallel-tracking arm on an air bearing, and in 2008 the 4Point, a pivoted arm resting on four jewelled bearing points that Trei calls “an instant success”; 9-inch and 14-inch versions followed. Twelve-inch Stogi arms arrived in 2009, the lidded Stabi M in 2012, the XL DC and later the air-bearing XL Air from 2014, and the compact Stabi R, made from a solid block of aluminium, in 2018.

The newest direction is sapphire. The Safir 9 arm, which the company dates to 2022, uses a single tapered tube of lab-grown sapphire. In an interview in hi-fi+ issue 254, Franc Kuzma said tests showed such tubes to be inert up to 5kHz, and that a 12-inch sample tube alone takes six to nine months to produce; the longer Safir 12 followed with its own height-adjustment system. Trei weighed the Safir 9 against its price — $23,140 as tested in the US, against the $340 he once paid for a Stogi — and noted its 60g effective mass, more than double the usual threshold for a heavy arm. A 12-inch Safir prototype was shown at the High End show in Munich in May 2024, he wrote. The company says its 2025 work included a top cartridge with a one-piece diamond cantilever in a sapphire housing; its current list runs from the CAR-20 to the CAR-70.

Some things have not changed. Trei notes that the original Stogi is “still made by Kuzma in a form that’s nearly unchanged,” and the company says it still holds most of the spare parts for the first Stabi.

Design and documentation.

Beyond the best-known turntable brands sits a group of smaller engineering firms that concentrate on record players, tonearms and the parts around them. They are spread across Europe, Japan and the United States, and each gives its own address on its website.

In Europe, Kuzma gives its address as Kranj, in Slovenia. Three of the makers in this guide are German: Transrotor trades as Räke Hifi Vertrieb GmbH in Bergisch Gladbach, near Cologne; Acoustic Signature’s website names AS-Distribution GmbH in Süßen; and Dr. Feickert Analogue lists Dr. Christian Feickert at March-Buchheim, near Freiburg. Origin Live, in Southampton, says its products have been “made in Southampton, England since 1986.”

Outside Europe, TechDAS describes itself as the house brand of Stella Inc., a high-end audio distributor in Tokyo, and says all its products are made in Japan. Basis Audio gives its address as Hollis, New Hampshire, and calls its turntables “Hand-Built in the USA.”

Mass features in some of their own descriptions. TechDAS says its Air Force Zero weighs 330 kg, with a platter up to 40 cm across, yet argues that weight alone is not the measure of a record player; Basis offers a 23 lb hybrid alloy “Super Platter” for its Inspiration, while the platter of its 2200 is machined from acrylic.

Where these products are made is, in most cases, the companies’ own statement rather than a fact documented independently.

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.

A family firm in Kranj.

Kuzma has stayed small and in the family. Slovenia’s business register, as summarised by CompanyWall from AJPES data, lists the present company, Kuzma d.o.o., at Jelenčeva ulica 1 in Kranj, entered in the register in April 2003; its director, its sole owner and its authorised signatories — Franc Kuzma among them — are all members of the Kuzma family. That entry dates the current legal entity, not the brand. The same summary gives revenue of about €1 million and nine employees for 2025, and lists its main activity as the manufacture of consumer electronics. In English the company calls itself Kuzma Ltd.

On where its products are made, the company says production moved in 2011 from Hotemaže, a village near Kranj, to a factory in Kranj covering 2,000 square metres; we give that as its claim. It lists its materials as aluminium, brass, bronze, acrylic, and sapphire and mineral plates, and describes its assemblies as handmade. Stereophile says Kuzma has stuck “doggedly” to turntables, tonearms, cartridges and a few accessories, and that its setup manuals and packaging are now “among the best in the industry.” Its US importer is Elite Audio/Video Distribution in California. One naming trap: Kuzma is also the name of a municipality in Prekmurje, in the far north-east of Slovenia, and of several unrelated Slovenian businesses; the turntable maker is the company in Kranj at kuzma.si.

For a design guide, Kuzma shows how an engineering idea — rigidity, written into the very names Stabi and Stogi — can carry a brand for four decades in its founding family’s hands, as far as the sources we checked show. Compare SME, the British arm maker, and Linn, whose Ittok was the yardstick when the Stogi first reached Britain. For this guide we use machined aluminium, brass and a sapphire blue with a sans, an unofficial interpretation; no product or logo is reproduced.
