The very first integrated amplifier
The Accuphase-E650 is a flagship integrated amplifier that represents the pinnacle of the company's audio engineering expertise. It's the first Accuphase integrated amplifier to include the company's AAVA (Accuphase Analog Vari-gain Amplifier) volume control, which provides precise and linear volume adjustment with minimal distortion. Additionally, the AAVA circuitry eliminates the need for traditional volume control components such as resistors, resulting in a cleaner and more transparent signal path. The Accuphase-E 650 redefines integrated amplifier performance and demonstrates the company's dedication to innovation and quality.

Volume control for AAVA
The Accuphase E 650 incorporates the company's AAVA (Accuphase Analog Vari-gain Amplifier) volume control system, which provides precise and linear volume adjustment with minimal distortion. The AAVA circuitry creates a highly accurate volume control by combining an array of FETs and a ladder network, eliminating the need for traditional volume control components such as resistors. As a result, the signal path becomes cleaner and more transparent, allowing the amplifier to faithfully reproduce the subtle nuances and details of the original music. The AAVA volume control is just one of the many unique features that distinguish the Accuphase 650E integrated amplifier.
