C-2450 Stereo 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.

  • AAVA volume control for high performance and outstanding sound
  • Separate power transformers for left and right channels
  • Selectable preamp gain
  • Fully modular construction with individual left/right amplifier units on motherboard
  • Logic-controlled relays for shortest signal paths
  • Independent phase selection for each input position
  • Optional phono equalizer unit enables playback of analog records
  • Elegant side panels with natural wood grain finish
