Accuphase

When Kenwood's best engineers decided good enough wasn't

History

Accuphase Laboratory, Inc. was founded in Yokohama, Japan in 1972 by a group of engineers led by Jiro Kasuga who had previously worked at Kenwood (then Trio-Kenwood). Dissatisfied with the direction of mass-market audio, these engineers set out to create the ultimate high-fidelity components without compromise.

The company name combines "Accu" (accurate) with "phase" (referring to audio phase integrity)—reflecting their commitment to accurate sound reproduction. From the beginning, Accuphase adopted a distinctive champagne-gold finish and heavy construction that set their products apart visually.

The E-202 (1973), Accuphase's first integrated amplifier, established the template for all future products: massive power supplies, Class A operation, discrete circuitry, and exceptional build quality. The amplifier featured the dual-mono construction and precision attenuator that would become Accuphase trademarks.

Throughout the 1970s and 1980s, Accuphase expanded their lineup to include preamplifiers, power amplifiers, tuners, and ultimately digital sources. The P-300/C-200 pre/power combination and T-100 tuner became reference standards in Japanese high-end audio.

The company maintained its independence and refused to compromise on quality even as the audio industry shifted toward lower-cost manufacturing. Accuphase remains a family-owned business producing exclusively in Japan with a obsessive focus on quality control.

Legendary Products

Accuphase E-202 (1973) The first Accuphase integrated amplifier and the template for everything that followed. The E-202 delivered 50 watts per channel of pure Class A power with dual-mono construction and a precision stepped attenuator. It established the champagne-gold aesthetic.

Accuphase P-300 / C-200 (1970s) Flagship separates that represented the state-of-the-art in solid-state amplification. The P-300 power amplifier delivered 150 watts per channel with massive current capability, while the C-200 preamplifier offered reference-quality phono stages.

Accuphase T-100 / T-101 (1970s) Reference-quality FM tuners with exceptional sensitivity and selectivity. The T-100 featured discrete circuitry throughout and became a benchmark for analog FM reception.

Accuphase E-305 (1980s) A refined integrated amplifier that improved upon the E-202 formula with better power supplies, improved Class A circuitry, and the legendary build quality that defines Accuphase.
