Accuphase C-2150 Stereo Control Center

Description

Accuphase C-2150 Stereo Control Centre is now available on Tecnifi. The Accuphase C-2150 for the first time amalgamates a new topology called ANCC with the AAVA volume control principle. As an outcome, music reproduction is supple, elegant and full of transparency, with a spatial expression capability that eliminates the presence of any volume control circuit. With a functionality level close to higher-end models and a versatile array of input and output terminals, alongside the choice of adding option boards, the C-2150 renders fully immersive music enjoyment. This breakthrough control centre will effectively cater to the needs of even the most demanding music lover.

AAVA converts the music signal into 16 differently weighted current streams (1 / 2, 1 / 22 , … 1 / 215, 1 / 216) which are combined according to the position of the volume control knob, resulting in exactly the desired listening level.

The C-2150 uses ANCC topology for the I-V converter amplifier, balanced output amplifier, and headphone amplifier. This innovative topology adds a sub-amplifier for effectively canceling noise in the main amplifier circuit. The use of low-noise technology in the sub-amplifier (noise density: 1.5 nV / √Hz) further enhances the benefits of ANCC. By incorporating ANCC in the I-V converter amplifier and the balanced amplifier of the AAVA section, a further drastic reduction in noise is achieved, especially at low to medium volume level positions.

Separate unit amplifiers for left and right
The C-2150 comprises five separate amplifiers: input buffer, V-I converter, I-V converter, output buffer, and headphone. These are configured as five separate circuit boards arranged on a motherboard, providing ample space for components and ensuring outstanding reliability and performance. Left and right channels are kept completely separate to prevent unwanted electrical interaction.
