Found at a Wolverhampton hi-fi show in 1984.

Croft Acoustics began in the West Midlands in the early 1980s. The earliest independent account we found is by Paul Boak in Hi-Fi Answers in June 1984, which Croft later reprinted on its website. Boak had “stumbled upon” a demonstration at the Wolverhampton hi-fi show and described the company as “a small — OK, tiny — outfit that consists of two music lovers, Glenn Croft and Peter Bruty,” then in Wolverhampton but probably about to move to larger premises in north Birmingham. Croft is usually remembered as a one-man company, so the second name matters: in December 1984 Boak wrote again of the two partners at work “in their first year.” We found no later account of Bruty’s role.

The date of the start is approximate. Croft’s own website said in 2008 that Glenn Croft had been hand-making amplifiers “for almost 25 years,” and in 2009 “for 25 years”; Stereophile wrote in 2013 that the company had been “in business just 30 years.” Together these point to about 1983–84. Later writers placed the company in Birmingham — “our off kilter friends from Brum,” in one Hi-Fi News review — or in the Black Country.

A fuller origin story was told by Amar Biswas of Eminent Audio, Croft’s later marketing partner, and retold by the online magazine 6moons in 2006, which noted that it was “open to debate” whether Biswas was recounting history or creating a myth. In his version, Glenn Croft joined a group of Wolverhampton hi-fi enthusiasts in the late 1970s as their repairer of valve equipment and was asked to improve on a German copy of the American Futterman transformerless amplifier; the result became the Croft Series II, which made its debut at a hi-fi show at Himley Hall. We give it as their account.

No circuit boards, no output transformers, no brochures.

The first products were ambitious. Boak found that “every component is either hardwired or tag board mounted,” with no printed circuit boards at all. The range ran from a £380 preamplifier to a dual-mono preamplifier whose “Mega” power supply used four transformers and 30 valves, and to 110-watt output-transformerless monoblocks, using ten GE 6080 double triodes, at £2,500 a pair; he compared them with the American Futterman design. By December 1984 the partners had a prototype of a cheaper transformer-coupled power amplifier, “very loosely based on an old Leak circuit,” to sell for about £600.

The product that made Croft’s name was much cheaper still. In November 1985 Ken Kessler reported in Hi-Fi News that a £125 Croft valve preamplifier — the Micro — had cut the entry price for a valve preamp by half or more. The Series Four power amplifier of 1986, Martin Colloms wrote, came in “Croft’s ‘traditional’ chocolate colored enamel with gold lettering.” By 1991 Hi-Fi News was saying that Glenn Croft had spent a decade “giving more for the money than any other maker I can name,” partly by putting three preamplifiers in one shared chassis, told apart only by the size of their knobs.

He was famously uncommercial. Keith Howard, interviewing him for a profile also reprinted on Croft’s site, called him “the recluse of British valve amplifier manufacturers,” a man who insisted on written questions and whom dealers, until Eminent Audio took over distribution, had to contact by post. In 2004 Haden Boardman wrote in Hi-Fi World: “Never ask for sales brochures — they do not exist!” Kessler also reported that Croft had stopped using the term “OTL” after another company claimed it, and coined “CTC,” for Croft Transformerless Circuitry.

Valves and the British amplifier.

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.

Chocolate enamel, gold lettering, then plain black.

In 2002 Croft joined forces with Eminent Audio. Companies House records Eminent Audio Limited as incorporated in March 2002, with Glenn Croft and Amar Biswas as directors; Croft resigned in April 2007, and the company was dissolved in 2013. Hi-Fi+ said in 2002 that the partnership had added “that missing marketing dimension,” along with thick alloy fascias and illuminated badges in place of the earlier wooden fascias and brass trim. Croft’s website said in 2008 that he had “had to stop manufacture” in June 2007, and in 2009 announced a relaunch: the Micro 25 and Micro 25R preamplifiers at £700 and £1,400, the hybrid Series 7 power amplifiers, with a valve input and MOSFET output, and a phono stage released in May 2009 — all in the same plain case, “not spending any more than necessary on case work.”

That approach reached the United States. Stereophile’s Art Dudley reviewed the Croft Phono Integrated, effectively a Micro 25 and Series 7 in one box, in 2013 and found it “plain but cheaply elegant,” though John Atkinson’s measurements were sharply critical; in 2014 Sam Tellig added that “Croft is still made in the UK” and came in “any color you want, as long as it’s black.” Reviewers had long noticed the looks: a Hi-Fi Choice review from 2001, reprinted on Croft’s site, said Croft’s “brown and gold hues” recalled old Leak and Rogers amplifiers.

Croft’s status today rests on weaker evidence. We found no trade-press report on the business after Stereophile’s 2013–14 coverage; a 2025 StereoNET forum post said the amplifiers are no longer made, which we could not confirm. By December 2023 the croftacoustics.co.uk domain had been parked, and it no longer works as an official site.

For a design guide, Croft shows how a brand can be built almost entirely on what is inside the box. Compare Leak, whose valve amplifiers Croft’s were often compared with, and Icon Audio, another British valve maker. For this guide we use chocolate brown, gold and black with a serif, an unofficial interpretation; no product or logo is reproduced.
