New flagship Accuphase C-3900S preamplifier has arrived at MusicWorks and will make its long-awaited debut at the The Bristol HiFi Show later this month.
C-3900S is designed for uncompromising high-end audio, delivering exceptional transparency and refined, detailed sonic performance. It is the new reference, replacing C-3900 and representing the pinnacle of Accuphase preamplifier evolution. C-3900S is easily the best preamplifier this unique Japanese company has produced.

It improves upon its predecessor with enhanced ANCC (Accuphase Noise and Distortion Cancelling Circuit) technology for superior signal purity, fully balanced circuitry, and separated power transformers for each channel.

Key features:
- Improved signal-to-noise ratio through increased number of parallel output amplifiers
- Enhanced Dual Balanced AAVA volume control – better transparency and lower noise floor: a 30% reduction in noise compared to prior balanced AAVA models
- Improved headphone amp – redesigned, with fully discrete circuit and parallel push-pull output stage
- ANCC noise cancelling via secondary internal amplifier, minimising distortion
- Separate toroidal power transformers and independent unit amplifiers for left and right channels to eliminate interference.
- L/R balance adjustment increased to 115 steps from 33
- Increased robustness – refined internal structure and component layout. The chassis is reinforced for extreme rigidity, weighing approximately 25.3 kg
C-3900S is now available for demonstration and will make its UK debut as part of our Accuphase system in the Fyne Audio room at Bristol – Suite 1, ground floor.
