The Nakamichi Amplifier 1 is a remarkable integrated amplifier released in the early 1990s by a brand that was, by then, already synonymous with audiophile-level engineering. Known primarily for their world-class cassette decks, Nakamichi poured the same obsessive attention to detail into this solid-state amplifier—and it shows.
Visually imposing with its stealthy, matte-black chassis and minimalist front panel, the Amplifier 1 looks like it belongs in Batman’s cave. But it’s not just about looks: this amplifier is technologically advanced, acoustically refined, and seriously powerful.
At the heart of its design is Harmonic Time Alignment technology—Nakamichi’s proprietary circuit architecture that ensures the timing and phase alignment of both the musical signal and distortion components across the full audio spectrum. This is achieved through a wide-band, low-gain open-loop design that minimizes negative feedback (NFB) while maintaining precision and stability, offering a transparent and natural sound with excellent dynamics.
Key technical features:
Motor-driven master volume for remote-controlled fine adjustments
8 output transistors in a parallel configuration
Peak current delivery of 28 Amps, allowing it to drive complex speaker loads with ease
Multi-regulated power supply, including separate transformer windings for each functional block (preamp, power amp, control), improving isolation and minimizing crosstalk
Isolated grounding scheme to reduce internal noise and hum
Gold-plated connectors, including dedicated CD direct input (bypassing all selector circuitry)
MM/MC phono input with dedicated switch on the back panel
High-gain phono equalizer stage with transistor differential input
Remote control for source selection and motorised volume via a quad-potentiometer
With its clean yet powerful sonic signature, beautifully engineered circuit topology, and robust build (weighing in at over 15kg), the Nakamichi Amplifier 1 remains a hidden gem in the world of vintage high-end audio. Highly collectible, highly listenable, and—simply put—great.
