Accuphase C-2450 Preamplifier 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 operation 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.
