A preamplifier built to answer a listening question.

Conrad-Johnson — the company writes its name in lower case, conrad-johnson — was started in 1977 by Dr. William “Bill” Conrad and Dr. Lewis “Lew” Johnson. Both held doctorates in economics, Conrad from MIT and Johnson from the University of Washington, and they met as research economists at the Federal Reserve Board in Washington, D.C., according to Positive Feedback and The Absolute Sound. The company says the two friends were dissatisfied with the equipment they could buy and puzzled by the audible differences between the two classic tube systems they owned. “Could the virtues of each be somehow combined?” its history asks. Johnson told Positive Feedback in 2017 that they studied older circuits, naming the Marantz 7 as the greatest influence, alongside Dynaco designs, and spent about 18 months turning their preamplifier into a product.

That product, sold first simply as the conrad-johnson Preamplifier and later named the PV1, had two phono inputs and a regulated high-voltage power supply, and its literature stressed “metal film resistors and polyester and silvered mica capacitors,” the company says. It was reviewed in The Absolute Sound in 1978, where Harry Pearson gave it a Class I recommendation, at a price of $585. The founders kept their day jobs at first — a safety net Johnson said they were glad of in the 1981 recession — and tried selling direct for only nine months before turning to dealers.

The company is now based in Fairfax, Virginia, in the Washington suburbs; we did not find an independent record of where the first preamplifiers were assembled. Note too that the Johnson in conrad-johnson is not William Z. Johnson, who founded Audio Research in Minnesota in 1970 — two unrelated Johnsons behind two of the American tube makers of the 1970s.

From the MV75 to the ART.

Products followed steadily. According to the company’s own timeline, reproduced by its Japanese importer, the MV75 of 1978 was its first power amplifier and the Premier One of 1979 a 200-watt-per-channel tube amplifier, at a time when tubes were associated with low power; Johnson told Positive Feedback that “it drove speakers that wouldn’t normally run with tube amplifiers.” The Premier Three preamplifier and the PV5 followed in 1983, the Premier Seven in 1988 and the 275-watt Premier Eight mono amplifier in 1992. The company also worked beyond tubes: a solid-state MC7 under a sister brand, motif, in 1985; a low-priced Sonographe SD1 CD player in 1986; and, Positive Feedback notes, Synthesis loudspeakers and McCormack Audio — an American venture not to be confused with the Italian Synthesis.

For its 20th anniversary in 1997 it introduced the ART, short for Anniversary Reference Triode, a dual-mono line-stage preamplifier; Johnson said he was proudest of it, “in part for its industrial design.” The later GAT preamplifier was named after Carnell Gatling, a longtime employee who packed the products and acted as the final quality check, Johnson said. By Myles B. Astor’s count in Positive Feedback in 2017, the company had made 94 earlier products, alongside nine current ones. Johnson added that it preferred long model runs, of two to seven years or more, gathering changes into significant updates rather than yearly revisions.

The founders did not sell to an outside group. The Audio Beat reported in August 2017 that Conrad and Johnson had sold the company to Jeff Fischel, its longtime senior technician and general manager, who had joined in the late 1980s; there was no press release, Copper noted. Johnson said they wanted to give Fischel a “fresh start” with new products, including the KT150-based ART300 monoblocks for the 40th anniversary, with a new industrial design by Johnson, and the company’s first headphone amplifier. In December 2020 The Absolute Sound inducted the two founders into its High-End Audio Hall of Fame, wishing them “a happy and peaceful retirement.”

American hi-fi and its records.

American high-end audio grew into a movement in the 1960s and 1970s, with its own press: Stereophile, founded in 1962 by J. Gordon Holt, and The Absolute Sound, founded in 1973 by Harry Pearson, according to English Wikipedia.

The makers grew up far apart. In Minnesota, William Z. Johnson founded Audio Research in Minneapolis in 1970, and Jim Winey’s Magnepan loudspeaker dates from 1969. In Connecticut, Mark Levinson started his company in 1972, and Dan and Rondi D’Agostino founded Krell in 1980. In Kentucky, Thiel began in Lexington in 1976; and in California, Richard Vandersteen took his Model 2 to the 1977 Consumer Electronics Show.

Several later changed hands. The Mark Levinson name passed to Madrigal Audio Laboratories at a bankruptcy auction in 1985, and Harman acquired Madrigal in 1995, Harman says; Samsung bought Harman in 2017. Audio Research was bought in 2008 by the Italian investor Quadrivio, whose Fine Sounds group was later renamed McIntosh Group, and was sold on in 2020 and 2023. Thiel was sold to a Nashville investor in 2012 and stopped operating in 2018. Krell closed after Rondi D’Agostino’s death in 2024; its repair service restarted in 2025, trade reports say.

Today Audio Research is in Maple Grove and Magnepan in White Bear Lake, Minnesota; Mark Levinson is part of Harman, based in Stamford, Connecticut; Krell remains in Connecticut; conrad-johnson builds by hand in Virginia; and Vandersteen is in Hanford, California, according to their websites and English Wikipedia.

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.

Champagne casework and a lower-case name.

The look was set early. Reporting the 2017 sale, Copper, the magazine published by PS Audio, said the first preamplifier’s “champagne casework and lower case conrad-johnson logo brought to mind early Marantz.” The company still writes its name in lower case on its website, and its slogan, repeated in its design statement, is “It just sounds right.” No official colour values or typeface for the logo are published.

Today conrad-johnson design, inc. gives its address as 2800K Dorr Avenue, Fairfax, Virginia. It says its products use proprietary CJD film capacitors and transformers and in-house-designed circuit boards, chassis and metalwork, “all sourced from North American vendors,” and that “all c-j components are designed and built by hand in the USA”; we give those as company claims. Its current range, listed with prices on its website, includes the ART 88 preamplifier, the ART27A, ART108A, ART150 and ART300 amplifiers, the Classic 62 and Classic 120 amplifiers, the CAV-60 control amplifier, ART and Classic phono stages and the HVA-1 headphone amplifier. We found no report of a change of ownership since the 2017 sale, and no published figures for revenue or staff.

For a design guide, conrad-johnson shows how a small company can keep a recognisable face for nearly five decades. Compare Audio Research, the Minnesota tube maker, and Pass Labs. For this guide we use champagne, brass and a deep brown-black with a sans, an unofficial interpretation; no product or logo is reproduced.
