A valve amplifier at a Brno trade fair.

Canor makes valve amplifiers in Prešov, in eastern Slovakia, and dates itself to 1995. Its German distributor, IDC Klaassen, says the first product, the TP101 integrated valve amplifier, was shown as a prototype at the trade fair in Brno, in the Czech Republic, in April 1995; the company’s own timeline calls it a “wooden-stainless steel” design. The founder named in every account is Zdeněk Březovják, the son of a musician, who learned the violin and tenor saxophone before turning to the technical side of sound, studied electrical engineering with a specialism in radio electronics and, the distributor says, worked at a maker of professional PA amplifiers before going into business with friends in the early 1990s. He remains the company’s chief developer and a co-owner.

The name came later. The Slovak business register records the company as EDGAR, spol. s r.o., set up by a partnership agreement in February 2000 and entered in the register on 11 April 2000, and renamed CANOR, spol. s r.o. on 15 November 2007. The company says it rebranded Edgar as Canor in 2007; the German magazine Fidelity says the new name is Latin for “sound.”

Sources differ on the founding date. The company uses 1995, the year of the first amplifier, while the German site LowBeats, in an April 2024 factory report, gave 2000 and said the Canor name dated from 2008. The register explains the first difference — 1995 is the product, 2000 the company — and gives 2007 for the second.

Ownership has stayed with the founders. The register lists three partners and managing directors since 2000 — Březovják, Ján Koščo and Jozef Čurlík — holding roughly equal shares, and LowBeats named Koščo as chairman. We found no corporate parent.

A factory behind other names.

Canor is better known inside the industry as a contract manufacturer. Fidelity’s Carsten Barnbeck wrote that because one niche integrated amplifier could not support the business, the partners set up contract manufacturing for other brands alongside the Edgar range, helped by Slovakia’s lower production costs in the late 1990s and 2000s; the magazine said the clients were confidential. LowBeats editor Holger Biermann, visiting in April 2024, was more specific. He reported that all of Pro-Ject’s electronic components are made in Prešov, along with products for IsoTek and Musical Fidelity — the latter, he noted, now part of Pro-Ject owner Heinz Lichtenegger’s group — and that IsoTek occupied about half of the production space. Canor, he wrote, “lives mainly from the OEM business.” Fidelity added that its own amplifiers became properly available in Germany only in 2020, when IDC Klaassen took over distribution there.

The company describes a vertically integrated factory. Its timeline lists a new 1,300-square-metre office and production building in 2011 — the register shows the move to Družstevná street that November — a system for measuring and matching valves in 2012, an 8,000-square-metre manufacturing facility in 2015 and more than 80 employees by 2020. LowBeats counted 87 employees, a production building of more than 3,000 square metres with further space sublet, and a separate development building with a line for surface-mount circuit boards. It described in-house metal milling, anodising and laser engraving of front panels, and quoted a marketing manager who put output at “several tens of thousands” of units a year. The register has listed metal electroplating among the company’s activities since 2007, and Fidelity says a system called Aladdin automatically tests every incoming valve.

Design and documentation.

Central Europe’s audio industry has a long state-era record. In Poland, Unitra, the association of consumer-electronics makers, was set up in 1961 and kept its original structure until 1989, English Wikipedia says; the Tonsil loudspeaker works in Września, founded in 1945, ran as a state enterprise until 1990, according to Polish Wikipedia. In Czechoslovakia, Tesla was the state conglomerate that monopolised electronic appliances and components from 1946 until its privatisation in 1991.

The region has since become a workshop for Western brands as well as its own. Pro-Ject, founded in 1991 in Mistelbach, Austria, designs at home and makes its products in Germany, the Czech Republic and Slovakia, English Wikipedia says; the German magazine lowbeats reported after a factory visit that Canor’s plant in Prešov makes all of Pro-Ject’s electronic components, and those of IsoTek and Musical Fidelity.

The trade meets in Warsaw, where the Audio Video Show holds its 28th edition in October 2026; its organisers call it the world’s second-largest audio show.

The seven makers in this guide are spread across the region, according to their websites and business listings: Pylon Audio in Jarocin and Fezz Audio near Białystok, in Poland; Ancient Audio in Kraków; Mytek, founded in New York in 1992, with a European branch in Warsaw; Xavian at Hostivice, outside Prague; Canor in Prešov, in eastern Slovakia; and Ayon at Gratkorn, near Graz, in Austria.

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.

Valves under its own name.

Under its own name Canor makes valve and hybrid electronics. The early range ran from the TP101 to the TP105 of 2005, which the company calls Edgar’s first model with enclosed valves, and later integrateds such as the TP106 and TP134; then came the AI 1.10 and AI 2.10 amplifiers, the PH 1.10 and PH 2.10 phono stages and CD players. The reference line pairs the Hyperion P1 valve preamplifier with the Virtus M1 monoblocks. More recently the British engineer John Westlake, known for his work on Audiolab, Leak and Quad electronics, joined the company, and LowBeats reported that the Virtus A3 integrated amplifier was largely his concept, at a probable price of €5,900, with power-amplifier circuitry that, the site said, takes a modernised form of the old Quad 405. Canor’s own awards page lists a 2023 Analog Grand Prix Gold award for the PH 1.10, a 2023 Stereo Sound Grand Prix for the Virtus M1 and Diapason d’Or awards, among others.

The company says development, production and testing are kept “under one roof” in Prešov. We found no official account of its logo, typeface or colours.

For a design guide, Canor shows a brand that sits on top of a factory: a small range under its own name, while much of its output carries other makers’ names. Compare Pro-Ject, whose electronics LowBeats reported are built in Prešov, and Xavian, a Czech loudspeaker maker. For this guide we use graphite, aluminium grey and a valve amber with a sans, an unofficial interpretation; no product or logo is reproduced.
