Precision Stereo Control

Accuphase make some of the finest equipment in the world and we can't recommend them highly enough. All of their components will deliver a marked improvement to any system and are a fantastic base to a new build or an unparalleled upgrade to an existing one. Accuphase amplifiers will deliver all the power you need with very low noise levels.

Blending the purely analog AAVA volume control circuit with sophisticated technology inherited from the C-2850 results in superb S/N ratio and a refinement of expression that brings new clarity to the music. The utterly smooth feel of the volume sensor assembly and a top plate made of brushed aluminum with a hairline finish demonstrate a level of dedication and hands-on craftsmanship that pervades every aspect of this preamplifier. Each C-2450 is individually honed to provide nothing short of perfection.
