Accuphase C-3900
At the very pinnacle of the Accuphase range is the C-3900 preamplifier.
This is a terrific preamp and, despite us intending to buy ‘just’ the c-2900 to supplement the C-2150 for demonstration, we found it impossible to ignore.
Along with C-2150 & C-2900, we have the C-3900 on permanent demonstration.
To celebrate the 50th anniversary of Accuphase’s founding, the development of a new flagship model to incorporate the entire wealth of the company’s experience was begun. Now, after five years, the work is complete. The C-3900 represents an uncompromising harmony of technology and sensibility, boasting ultimate performance and sound quality that ushers in a new era of the preamplifier. The Dual Balanced AAVA design with two balanced AAVA circuits delivers sonic excellence that is transparence itself. Volume adjustment is realized while retaining all the vibrant energy and richness of detail that is the life breath of an artistic performance. The supple elegance of music as reproduced by the top-of-the-line C-3900 is a moving experience that reflects the impressive depth of Accuphase know-how.

High-accuracy, high-rigidity volume sensor construction
The volume sensor mechanism performs the task of detecting the angular position of the volume knob. Accuphase has developed the volume sensor in-house, using a massive aluminum block extruded and finished with utmost precision. The knob provides an utterly solid and smooth operation feel and achieves extremely accurate position detection. When using the Remote Commander, a motor drives the volume knob via a set of gears. Generally, gears produce a meshing sound when rotating, but this position sensor is designed so that the gears mesh with each other while always maintaining a constant pressure, which enables super quiet and comfortable volume adjustment.
