Luxman R-1120 (1978–1979)
At 17 kg, it lands on the rack like a declaration — this is not a receiver built to cut corners, but one engineered to dominate the late-’70s high-fidelity arms race.
Overview
The Luxman R-1120 is a solid-state AM/FM stereo receiver introduced in 1978 as the “long awaited advent of super powered ‘tuner-amplifier’ from Luxman,” according to classicreceivers.com. Manufactured in Japan, it was positioned squarely in the upper echelon of the receiver wars, where power ratings and build quality were the primary battlegrounds. Priced at approximately $995 USD (or 2,300 DM in Europe) at launch, it targeted serious audiophiles who demanded more than just wattage — they wanted refinement, protection circuitry, and a tuner section that could hold its own against separates. At 120 watts per channel into 8 ohms (20–20,000 Hz, both channels driven, THD no more than 0.03%), the R-1120 wasn’t just powerful for its time — it was conservatively rated, suggesting headroom that many competitors lacked. Its 88 dB signal-to-noise ratio on line inputs and 72 dB on MM phono reflects a design that prioritized quiet backgrounds, crucial for extracting detail from vinyl. The chassis, measuring 490 x 180 x 415 mm (W×H×D) and weighing 17 kg (38 lbs), is substantial without being excessive, and the wood cabinet with vinyl woodgrain covering gives it the period-correct aesthetic — though owners report the vinyl covering is prone to shrinking over time, a common flaw with finishes of that era.
120-Watt Solid-State Power Amplifier with Low Distortion
Delivering 120 watts per channel into 8 ohms across the full 20–20,000 Hz bandwidth with no more than 0.03% total harmonic distortion, the R-1120’s amplifier section was engineered for both authority and accuracy. This wasn’t the kind of receiver that inflated its specs with short-term power bursts or narrow bandwidth claims — the rating was full-range, continuous, and both channels driven, a testament to Luxman’s conservative engineering philosophy. The high damping factor implied by its robust power supply and output stage allows it to control difficult speaker loads with authority, a trait that owners still praise decades later. Audio (March 1979, p.75) noted that Luxman amplifiers “were never intended to compete with typical receivers—those that equate output power with performance,” underscoring that the R-1120’s strength lies not in raw numbers, but in how cleanly and reliably it delivers them. One owner on HiFi Engine went further, calling it “one of the best receivers ever produced,” a sentiment echoed by those who’ve paired it with demanding speakers. However, that power comes with a vulnerability: multiple owners report catastrophic transistor failures, with one noting a complete channel replacement involving output, driver, and pre-driver transistors. Such repairs are feasible but not trivial, and some have opted to upgrade with modern low-noise transistors to improve reliability and performance.
Triple Speaker Outputs with Protection and Muting Circuits
Equipped with three pairs of speaker terminals, the R-1120 allows users to run multiple speaker sets — a practical feature for multi-room setups or A/B comparisons. But Luxman didn’t just add terminals; it backed them with intelligent circuitry. A power limiter circuit actively protects the output transistors from excessive current, a safeguard that likely saved many units from thermal runaway during mismatched loads or prolonged high-volume operation. Complementing this is a time-delay muting circuit that prevents turn-on thumps, preserving both speaker drivers and eardrums. These features weren’t universal in 1978, and their inclusion signals Luxman’s focus on longevity and user experience over cost-cutting. The receiver’s 500 W maximum power consumption reflects the demands of its dual-channel 120 W design, requiring a robust AC line — something potential users should consider when integrating it into modern setups.
FM/AM Tuner with High Sensitivity and Stereo Quietening
The R-1120’s FM tuner section was a standout for its time, offering high sensitivity and strong stereo quieting performance. HiFi-Stereo (June 1978, p.133) reported that stereo quieting reaches 60 dB with only 45.5 dBf of input, promising “enjoyable listening in all but the deepest fringe areas.” This means the tuner can lock onto weak or distant stations with minimal noise, a crucial advantage in pre-satellite, pre-internet audio. The tuning range covers FM and MW (medium wave), with inputs supporting both MM (2.7 mV) and MC (0.18 mV) phono cartridges, each with 47 kOhm impedance. The inclusion of a fully specified MC input — rare in receivers — suggests Luxman expected this unit to be paired with high-end turntables, not just casual record players. The tuner’s performance aligns with Luxman’s reputation for separating itself from mass-market receivers, which often skimped on RF stages to save costs.
Historical Context
The Luxman R-1120 arrived in 1978, at the height of the receiver wars — a period when Japanese manufacturers flooded the market with increasingly powerful, feature-laden stereo receivers. While many brands chased wattage wars with inflated specs, Luxman took a different path, emphasizing measured performance, build quality, and circuit integrity. Marketed as a “super powered tuner-amplifier,” the R-1120 was positioned as a high-end alternative to separates, offering near-preamp levels of refinement in a single chassis. It was not a budget offering; at $995, it competed with mid-tier separates systems. Its design philosophy — low distortion, robust power supply, and protective circuitry — reflected a belief that reliability and sonic accuracy mattered more than marketing numbers. The R-1120 stands apart from its sibling, the R-1120A, which collectors consistently describe as “less sought after,” implying a step down in performance or desirability.
Collectibility & Value
Despite its age, the Luxman R-1120 maintains a loyal following among vintage audio enthusiasts. Units in excellent condition have sold for as much as $1,000, with a 2011 sale of an excellent-condition unit fetching $400 — a figure that now seems low given current demand. A February 2024 Facebook listing offered the receiver with a Dual CS 5000 turntable for $1,400, suggesting strong market interest in matched vintage systems. In Europe, a listing on HifiShark priced one at CZK 29,500 (approximately $1,200 USD), and one owner famously declared, “luxman r1120 owes me £900,” indicating both emotional and financial investment. However, collectibility comes with caveats: the vinyl woodgrain covering is known to shrink and peel, and transistor failures — particularly in the output stage — are a documented issue. Repairs are possible, and some owners have upgraded internal components for improved longevity. Its status as a “super powered” receiver from Luxman’s golden era ensures it remains a sought-after piece for those who value engineering over nostalgia.
