A Buyer’s Guide to conrad-johnson
A chapter of HFR’s Complete Buyer’s Guide to High-End Audio
conrad-johnson is an American maker of vacuum-tube electronics, founded in 1977 in Fairfax, Virginia by two Federal Reserve Board economists — Dr. William Conrad (MIT PhD) and Dr. Lewis Johnson (University of Washington PhD) — who bonded over a shared frustration with contemporary solid-state gear compared to the tube designs of Dynaco, Leak, and Marantz.
Bill and Lew sold the company in 2017 to Jeff Fischel, their longtime Senior Technician and General Manager, and remain actively involved in marketing conrad-johnson today. Both were inducted into The Absolute Sound’s High-End Audio Hall of Fame for their role in the tube renaissance of the 1980s and ’90s.
This guide covers conrad-johnson’s founding story, its design philosophy, the current product line, and what to know before buying used.
conrad-johnson: The Brand
Bill Conrad and Lew Johnson met as research economists at the Federal Reserve Board in Washington, D.C., and discovered a shared passion for audio — and a shared disappointment with the solid-state equipment of the mid-1970s compared to the tube designs of an earlier era. They set out to combine the qualities they liked from classic tube gear while eliminating what they didn’t, at a reasonable price — and kept their Federal Reserve jobs as a financial safety net while they developed their first products.
The PV1 preamplifier, priced at $585, was conrad-johnson’s 1977 debut — a simple circuit with two phono inputs, a cathode-follower linestage output, and a regulated power supply, setting the tone for Bill Conrad’s long-running emphasis on power-supply engineering. It earned a Class I recommendation from High Performance magazine in 1978, the company’s first favorable review.
The MV75 power amplifier followed later in 1978, and its success did as much as the PV1 to establish conrad-johnson as a serious audio company — it went through several running revisions (the MV75A added high-voltage fuses and swapped Mylar capacitors for polypropylene; the MV75A-1 lowered the impedance of the regulated power supplies feeding the voltage-gain and phase-inverter stages). In 1979, the Premier One — a 200-watt-per-channel all-tube amplifier and conrad-johnson’s first “state of the art” product — was named the finest-sounding amplifier of the 1980s by The Absolute Sound’s 10th Anniversary issue.
Ownership transition
Over more than 40 years, conrad-johnson launched close to 100 products. In 2017, Conrad and Johnson sold the company to Jeff Fischel, who had been conrad-johnson’s Senior Technician and General Manager since the late 1980s and now leads product development and engineering. Both founders remain actively involved in marketing conrad-johnson, and both were inducted into The Absolute Sound’s High-End Audio Hall of Fame for their contributions to the tube renaissance.
Design Philosophy
conrad-johnson’s stated approach is simple circuits built from the highest-quality custom components, with every conrad-johnson component designed and hand-built in the USA from North American-sourced parts. Several current preamplifiers — including the PV11 and GAT Series 2 — use no negative feedback in the audio circuit at all, on the position that negative feedback introduces temporal inaccuracies that a zero-feedback design avoids.
The company’s signature part is its own CJD Teflon capacitor: a proprietary DuPont Teflon film made to conrad-johnson’s specification, with a proprietary copper-rich end spray and custom leads and solder, hand-wound by technicians with 20-plus years of experience and inspected at three separate QC stations. The design goal is minimizing Dielectric Absorption (DA) — a capacitor’s “sonic memory” — which conrad-johnson says can run several percent on electrolytic capacitors versus under 1/100th of a percent on a Teflon design.
Iconic Model Families
PV1 — the founding preamplifier (1977)
conrad-johnson’s first product and the origin of the company’s power-supply-first design priority: a simple two-phono-input preamp with a cathode-follower linestage output and a regulated power supply, priced at $585.
MV75 — the amplifier that cemented the brand (1978)
conrad-johnson’s first power amplifier and, alongside the PV1, the product credited with establishing the company’s long-term viability. Refined through the MV75A (high-voltage fuse protection, polypropylene caps in place of Mylar) and MV75A-1 (lower-impedance regulated power supplies) revisions.
Premier One — the first flagship (1979)
A 200-watt-per-channel all-tube power amplifier, conrad-johnson’s first “state of the art” product and, per The Absolute Sound’s 10th Anniversary issue, the finest-sounding amplifier of the 1980s.
ART88 — the current flagship preamplifier
conrad-johnson’s current top preamplifier, priced at $28,000, built around paralleled twin-triode gain and buffer stages using NOS Philips PCC88 tubes. Reviewers describe it as a return to pure valve audio circuits and, per owner reports, the best-sounding conrad-johnson tube preamplifier the company has made.
Current Product Line (2025–2026)
conrad-johnson’s current lineup is organized into three tiers, all designed and hand-built in Fairfax, Virginia.
ART series (flagship)
ART88 preamplifier ($28,000), ART Phono phono preamplifier ($28,000), ART27A power amplifier ($22,000), ART108A monoblock power amplifiers ($52,000/pair), ART300 monoblock power amplifiers ($42,000/pair), ART150 power amplifier ($21,000).
ET series (mid-premium)
ET7-S2 preamplifier ($15,500), ET6 and ET6SE preamplifiers ($6,600–$9,750).
Classic series (mid-range)
Classic 120 power amplifier ($11,000–$13,500), Classic 62 power amplifier ($6,750–$7,750), Classic Phono phono preamplifier ($7,000–$9,000).
Other current products
CAV-60 control amplifier ($6,750), HVA-1 headphone amplifier ($7,500).
Buying Used conrad-johnson
conrad-johnson’s used market is unusual in one important respect: the company services every product it has ever built, and runs formal factory upgrade programs on a long list of legacy models. A used-buying framework:
Ask whether the unit has had a factory capacitor upgrade. conrad-johnson’s Capacitor Upgrade program covers the ART/ART2, ET2/ET3, Evolution series, Classic, and Premier Seven through 17LS preamps; EV1, Premier 15, and TEA2 phono stages; and CAV50, LP-series, MV50–125, and Premier Four through Premier 140 amplifiers, replacing older capacitors with current CJD Teflon parts. A unit that’s had this done is a meaningfully different — and typically more valuable — purchase than an all-original example of the same age.
Ask about tube age and hours
Tube complement and hours in service directly affect near-term cost of ownership on any conrad-johnson tube product. Ask when the tubes were last replaced and whether the seller has spares.
Factory service is a real, usable option
Because conrad-johnson supports its entire back catalog, a pre-purchase service estimate from the factory (703-698-8581 ext. 302) is a realistic step most other vintage-tube brands can’t offer in the same way.
Vintage vs. current-era units
Earlier conrad-johnson gear (Premier and PV series) carries a different, often warmer sonic reputation than the current ART-series designs; decide which era’s sound you actually want before shopping by model name alone.
conrad-johnson on the Used Market
conrad-johnson’s long production history and factory service continuity mean used pricing spans a wide range by era and model. A few real reference points rather than a comprehensive table: a used Premier 140 amplifier (original retail around $7,000) has recently asked between roughly $1,700 and $3,400 in the US secondhand market, with capacitor-upgraded examples commanding more. A used Premier Eleven has asked between roughly $2,550 and $6,237.
As with any tube gear, condition, tube complement, and whether a factory capacitor upgrade has been performed all move the price meaningfully — treat any specific asking price as a starting point for negotiation, not a fixed value.
Frequently Asked Questions
Who founded conrad-johnson?
Dr. William Conrad (a PhD economist from MIT) and Dr. Lewis Johnson (a PhD economist from the University of Washington). The two met working as research economists at the Federal Reserve Board in Washington, D.C., and bonded over a shared frustration with contemporary solid-state gear compared to classic tube designs from brands like Dynaco, Leak, and Marantz. They founded conrad-johnson in 1977 while still keeping their Federal Reserve jobs as a safety net.
Is conrad-johnson still owned by Bill Conrad and Lew Johnson?
No. In 2017, Conrad and Johnson sold the company to Jeff Fischel, their longtime Senior Technician and General Manager who had been with conrad-johnson since the late 1980s. Both founders remain actively involved in marketing, and both were inducted into The Absolute Sound’s High-End Audio Hall of Fame for their contributions to the tube renaissance of the 1980s and ’90s.
What was conrad-johnson’s first product?
The PV1 preamplifier, priced at $585 in 1977. It used a simple circuit with two phono inputs, a cathode-follower linestage output, and a regulated power supply — establishing Bill Conrad’s long-running design priority on power-supply engineering. It received a Class I recommendation from High Performance magazine in 1978, the company’s first favorable review.
What are CJD Teflon capacitors?
conrad-johnson’s proprietary capacitor, built from a DuPont Teflon film made to the company’s own specification, with a proprietary copper-rich end spray and custom leads and solder. Each capacitor is hand-wound by technicians with 20-plus years of experience and passes through three separate QC inspection stations. The design target is minimizing Dielectric Absorption (DA) — a capacitor’s “sonic memory” — which can run several percent on electrolytic capacitors but under 1/100th of a percent on Teflon designs.
What is conrad-johnson’s current product lineup?
Three tiers: ART (flagship — ART88 preamp, ART Phono, ART27A/ART108A/ART300/ART150 power amps), ET (mid-premium — ET7-S2 and ET6/ET6SE preamps), and Classic (mid-range — Classic 120 and Classic 62 amps, Classic Phono). The CAV-60 control amplifier and HVA-1 headphone amplifier sit outside the three-tier structure.
Does conrad-johnson service old products?
Yes — conrad-johnson offers factory upgrade programs covering a long list of legacy products, including the ART/ART2, ET2/ET3, Evolution series, Classic, and Premier Seven through 17LS preamps; EV1, Premier 15, and TEA2 phono stages; and CAV50, LP-series, MV50 through MV125, and Premier Four through Premier 140 power amps. The core offering is a Capacitor Upgrade that replaces older capacitors with current CJD Teflon capacitors, plus a separately named C1 Capacitor Upgrade program. Contact conrad-johnson customer service directly (703-698-8581 ext. 302) for eligibility and current pricing on a specific unit.
What does conrad-johnson’s zero-feedback design mean?
Several conrad-johnson preamplifiers, including the PV11 and GAT Series 2, use no negative feedback in their audio circuit. conrad-johnson’s position is that negative feedback introduces temporal inaccuracies that a zero-feedback circuit avoids, which the company credits for its preamps’ ability to track subtle tempo and dynamic changes.
What was the Premier One?
conrad-johnson’s first “state of the art” product, introduced in 1979: a 200-watt-per-channel all-tube power amplifier. The Absolute Sound’s 10th Anniversary issue named it the finest-sounding amplifier of the 1980s.
Where can I buy conrad-johnson in the United States?
Through conrad-johnson’s authorized dealer network, including The Audio Salon (Los Angeles), Music Lovers Audio (San Francisco and Berkeley), Deja Vu Audio (Vienna, Virginia), and 2020 Evolution (Potomac, Maryland). conrad-johnson also maintains a dealer locator at conradjohnson.com for the full current list.
What should I check before buying a used conrad-johnson tube unit?
Ask when the tubes were last replaced and whether the unit has had any factory capacitor upgrade performed — an upgraded unit with current CJD Teflon capacitors is a meaningfully different (and generally more valuable) purchase than an all-original example from the same era. Because conrad-johnson services everything it has ever built, a factory service estimate before purchase is realistic and worth requesting from the seller or directly from conrad-johnson.
