Accuphase Precision Stereo Preamplifier C-2850

Accuphase C-2850

C-2800 series renewal creates the ultimate preamplifier, the Accuphase C-2850. A new preamp generation defined by the harmony of craftsmanship and technology. The revolutionary AAVA (Accuphase Analog Vari-gain Amplifier) principle which enables optimal volume adjustment has been further refined, for ultra-low noise and utterly quiet operation, combined with perfect operation feel. Experience the ultimate in volume control performance and comfort from a component that is in a class of its own. Sophisticated technology and optimised construction using only carefully selected top-notch parts and materials provide effortless operation stability, with ample performance leeway that is the secret behind ultimate reliability. Each single C-2850 is lovingly built by highly experienced craftspeople skilled in the art. The result is a product destined to transport the listener into the enchanting realm of high-end audio.

Accuphase C-2850

Sound Quality – simply aiming for the best

Full mono construction. The power supply circuitry not only acts as the energy source of an amplifier, it also has a dramatic influence on its sound. The C-2850 features a newly developed type of high-efficiency toroidal transformer in a cast-aluminum case with thermal dissipation fins. Each channel has its own transformer, along with a pair of custom-made electrolytic filtering capacitors rated for high capacity and excellent sonic properties. This arrangement provides ample power reserves for effortless operation.

AAVA circuit is purely analogue. The AAVA circuit converts the input music signal into 16 types of weighted currents. According to the position of the volume control knob, the currents are then combined to determine the volume. The combined signal current forms a variable gain circuit that adjusts the level of the music signal.

Printed circuit boards made from glass fluorocarbon resin with low dielectric constant and low loss, and gold-plated PCB copper foil side.

High-rigidity, high-accuracy volume sensor mechanism with ultra smooth tactile feel. Turning the volume knob on the front panel causes the actual volume level position to be detected. The corresponding combination of weighted amplifiers then in turn adjusts the volume. The volume sensor mechanism is made of a massive aluminum block extruded and finished with utmost precision. The knob provides an exquisite tactile feel when rotated and ensures extremely accurate position detection. The entire mechanism is supported by a floating suspension using insulators, which also allows extremely quiet motor-driven operation when the remote commander is used.

Ideal left/right power supply configuration. Inside the preamplifier, circuits and components are securely mounted to a sturdy 8 mm thick aluminum frame and kept completely separate for the left and right channels. This reliably prevents unwanted mutual interference, resulting in further improved electrical characteristics and perfectly pure sonic performance.
