Accuphase C-200 (preamplifier) and P-300 (power amplifier), 1973, iconic for their sound quality and impeccable build. Vintage, collector’s items. Includes user manuals and a copy of the English-language brochure, to enhance the historical documentation of the units.
The Accuphase C-200 (preamplifier) and P-300 (power amplifier) represented one of the most iconic and highly regarded combinations in the history of hi-fi. Introduced by Accuphase, then known as Kensonic Laboratory, in 1973, they embodied the pinnacle of audio technology of that era, combining aesthetic elegance, precision engineering and a sound quality that set new standards in the hi-fi sector.
The C-200 was a reference preamplifier designed to offer particularly accurate audio signal handling, with a design focused on reducing distortion and background noise. In terms of construction, it featured a robust metal cabinet, finished with a brushed aluminium front panel. The ergonomic controls included selectors for multiple sources, tone controls, low-pass and high-pass filters, and a precision equalisation system. The internal design was conceived as a modular structure, with separate circuitry designed to reduce interference and preserve signal integrity.
From a technical perspective, the C-200 stood out for its phono stage, designed to ensure particularly accurate vinyl reproduction. The dynamic range was extremely wide and the frequency response extended from 10 Hz up to 100 kHz with an extremely linear curve. The signal-to-noise ratio was very high thanks to an advanced low-noise design, whilst the tone controls were engineered to allow for subtle and precise adjustments without compromising the fidelity of the original signal.
The P-300, on the other hand, was a solid-state power amplifier designed to deliver high power output and remarkable stability even under demanding operating conditions. Aesthetically, it shared the same elegance as the C-200, with a matching front panel and large illuminated VU meters that characterised the design of the early Accuphase models. The construction made extensive use of high-quality materials and featured oversized transformers and high-performance capacitors, elements that helped ensure a substantial power reserve.
The technical specifications highlighted an output power of 150 watts per channel into 8 ohms and 200 watts into 4 ohms, with remarkable stability even under complex loads. Total harmonic distortion remained below 0.1%, thanks to the use of fully symmetrical push-pull circuits, whilst the damping factor was high, allowing for particularly rigorous control of the speakers, especially the woofers.
The C-200 and P-300 combination offered musical reproduction characterised by transparency, detail and naturalness. The bass was powerful and well-defined, with a driving capability that ensured particularly precise control of the speakers. The midrange was rich and detailed, a quality that favoured a convincing rendering of vocals and acoustic instruments. The high frequencies stood out for their crystal-clear, smooth reproduction, with a linear response that avoided artificial colouration.
As Accuphase’s first product series, the C-200 and P-300 set the benchmark for vintage hi-fi enthusiasts and collectors. Their build quality, the longevity of their components and their sound performance still make them objects of great historical interest in the world of high fidelity. Their rarity, combined with the reputation of the Accuphase brand, contributed to making them particularly sought-after in the context of audio collecting.
The Accuphase C-200 and P-300 pairing thus stood as a significant testament to the technical excellence achieved by hi-fi in the 1970s. Their refined sound, meticulous construction and elegant design made them a symbol of the most advanced era of Japanese audio engineering.
The units had been refurbished and were in excellent cosmetic condition.
