Pioneer A-777

Brand: Pioneer

The Pioneer A-777 is an integrated amplifier that was introduced by the Pioneer Corporation in 1986. It featured a reproduction of the audio signal through a multi-stage process that aimed to deliver high-fidelity sound. This included the use of MOSFETs for the power stages and high-mu J-FETs for the preamp stages. The A-777 also included a proprietary Digital Pulse Control (DPC) circuit which offered very low distortion and high dynamic range distortion. The amplifier's output was rated at 95 watts per channel into 8 ohms and 180 watts per channel into 4 ohms. The A-777 was praised for its sound quality and efficiency, making it a popular choice among audio enthusiasts in the late '80s and early '90s.
