C-3900 Pre-Amplifier

Description

C-3900

The C-3900 is Accuphase's new flagship preamplifier developed to celebrate the 50th anniversary of the company's founding. Conventional preamplifiers attenuate the input signal by means of resistors and then amplify the result, which leads to an increase in noise. By contrast, AAVA performs direct volume adjustment through a combination of V-I (voltage-current) conversion circuits of different gain. Consequently, there are no changes in impedance or frequency response and sound quality remains impeccable. Any changes in noise level depending on the selected volume position are kept to an absolute minimum, thereby realizing outstanding S/N ratio also at commonly used listening levels. In the C-3900, the Balanced AAVA principle using two balanced AAVA circuits is further elevated by driving two such units in parallel, resulting in Dual Balanced AAVA which reduces the noise level by a further 30 percent compared to previous models. The volume sensor mechanism ensures utterly smooth operation with a solid feel and highly accurate volume knob position detection. The C-3900 is a top-of-the-line preamplifier that brings music to life with an emotional appeal such as never known before. Connecting the Stereo Phono Amplifier C-47 enables high-quality reproduction of analog records as well.
