A preamplifier built for one man’s own system.

Musical Fidelity was founded in 1982 by Antony Michaelson, a clarinettist who had studied at music college. Companies House records Musical Fidelity Limited as incorporated on 15 October 1982, and until 2018 its registered office was in Wembley, in north-west London. Before that, Michaelson had been a partner in Michaelson & Austin, which sold valve amplifiers in the late 1970s; in an interview on the company’s website he says simply that “that company went bust.”

His way back into audio, as he tells it, was a preamplifier he designed for his own system because he was tired of the mediocre one he owned. A dealer friend heard it and ordered some; “they all sold over the first weekend,” he says, and “almost by accident” he was back in business. The company’s timeline lists that first product, The Preamp, in 1982, followed by a “shoebox-style” power amplifier called the Dr Thomas. English Wikipedia credits that amplifier to Dr Martin Vaughan Thomas, but its citations for the early years are unreliable, so we give the detail with caution.

Michaelson kept playing. Between 1994 and 2004 he recorded clarinet works by Mozart, Brahms and Weber on a Musical Fidelity record label, English Wikipedia lists, citing Discogs — an unusual sideline for an amplifier company, and a reminder that it was run by a musician rather than an engineer.

The A1, the Nu-Vista and the kilowatt amplifiers.

The product that made the name was the A1 integrated amplifier. Stereophile, reviewing the reissue in September 2024, says the original “first appeared in 1985” and became famous for its hot top plate, which doubled as the heatsink for output transistors biased well into Class A; the company’s product page also says 1985, though its timeline gives 1984. Michaelson credited the circuit to the designer Tim de Paravicini, whom he had known since the Michaelson & Austin days. In a tribute after de Paravicini’s death in 2020 he called the A1 “the bestselling MF product of all time” and admitted that its difficult birth “almost put MF out of business.” Elsewhere he says it created a new class of “budget audiophile” amplifiers.

The range that followed went to extremes in both directions. The company lists the Digilog converter of the late 1980s, which it calls the world’s first high-end DAC — its own pages give both 1987 and 1988; the X series of small cylindrical components, which it dates to 1995 and English Wikipedia to 1997; the Nu-Vista preamplifier of 1997, built around miniature metal-cased nuvistor valves, of which it says all 500 units sold within three months; and the kW amplifiers of 2003 and the Titan of 2009, each rated at one kilowatt per channel.

Michaelson came to believe that appearance mattered as much as circuitry. Looking back on 30 years, he said he would tell his younger self “to lavish as much care on the external design of products as on the electronics,” because however good the circuit, “it has to look the part.” The company lists European Imaging and Sound Association (EISA) awards for the X-150 amplifier in 2004 and the M1 CLiC music player in 2011.

British amplifiers and their owners.

Britain’s second-tier amplifier makers are mostly small and founder-led. Sugden is in Heckmondwike, West Yorkshire; Creek in north London; Icon Audio in Leicester; Leema in Welshpool, mid-Wales; Exposure in Lancing, West Sussex. Musical Fidelity gives its Austrian owner’s Vienna address. Croft, found in Wolverhampton by Hi-Fi Answers in 1984, names no town on its now-lapsed website.

Several have changed hands. Musical Fidelity was sold in May 2018 to the Austrian group Audio Tuning. Creek was sold to Mordaunt-Short in 1988 and bought back in 1993 by Mike Creek and overseas distributors; its website now names Step Deeper Ltd as the brand’s owner. Companies House and Hi-Fi News show Exposure in Malaysian ownership for about two decades.

Sugden says the Miller family has run it since 1981. The original Leema company entered creditors’ voluntary liquidation in 2014; in February 2026 its successor registered a Dutch investment company as holding more than half its shares. Icon Audio says its founder, David Shaw, owns it outright.

Where products are made is mostly self-reported. Sugden says it makes cases and circuit boards in-house; Leema says it designs and manufactures in Wales; Exposure says it manufactures in Britain. Icon Audio says chassis are assembled at its own factory in China and finished in Leicester. Creek said in 2019 that it was moving production away from the Far East, and in 2020 that it had a new partner in Eastern Europe, without naming the country. Stereophile’s 2024 specifications for the reissued Musical Fidelity A1 read “Manufactured in Taiwan.”

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.

From Wembley to Vienna.

Michaelson decided to retire — in 2017, English Wikipedia says. On 8 May 2018, according to the company’s announcement, he sold Musical Fidelity to Audio Tuning Vertriebs GmbH of Austria, which is owned by Heinz Lichtenegger, founder of the turntable maker Pro-Ject; English Wikipedia gives the date as 14 May. Audio Tuning had been the brand’s Austrian distributor for more than 20 years, the announcement said, and Michaelson stayed on “in a design capacity.” The old British company was then wound up: Companies House shows a resolution in September 2018 to wind it up voluntarily, backed by a declaration of solvency, and its dissolution in September 2021.

Today the website describes Musical Fidelity as “a Division of Audio Tuning Vertriebs GmbH,” with an address in Vienna, and says the brand “still retains its proud British heritage.” Where its products are made is less clearly stated. The 2018 notice said “the existing factory will continue to be used” without saying where that factory was; Stereophile’s specifications for the reissued A1 in 2024 read “Manufactured in Taiwan,” and the company describes its LS5/9 loudspeaker as “Made in Europe.” Under the new owner the brand has leaned on its past — the reissued A1, which won an EISA award in 2024, the B1xi of 2025 and a revived X line — and has added BBC-design LS3/5A and LS5/9 loudspeakers alongside the M6xi, which the company says won an EISA award for 2026–2027. Stereophile listed the reissued A1’s finish as black with blue lettering.

For a design guide, Musical Fidelity shows how a founder’s taste — a musician’s ear and a belief that the box must look the part — can outlast the founder’s ownership. Compare Creek, another London amplifier maker founded in 1982, and Audiolab. For this guide we use near-black, brushed steel and a deep blue with a sans, an unofficial interpretation; no product or logo is reproduced.
