Yamaha A670 Stereo Amplfier in Black

Yamaha A670 stereo amplifier has a natural PWM type digital modulation with an extremely simple circuit configuration providing both natural, uncoloured sound quality as well as high efficiency.

Sound Quality

The low-pass filter of the latter part of the power amp greatly influences the sound quality and is a large coil made of low-loss, low-distortion OFC (oxygen-free copper) wire material. The high sound quality parts preserve the purity of the sound while the subwoofer output offers extra bass power. Simple and richly textured in design, the A670 is a amp that effectively performs the essential function of an amp to amplify signals while ensuring refined sound quality.

A digital power amp that creates high power and strong drivability with a strong maximum output of 65 watts/channel, every delicate nuance of music is delivered to an energy-filled dynamism. This simultaneously maintains the freshness of high-resolution sound sources, while enhancing the power of the bass and ensuring warmth in the mid and high frequency sounds—all to deliver the best quality sound reproduction, rich in musicality.

Purity Preserved

To prevent corrosion, all input and output jacks are gold-plated. High sound quality parts have been installed throughout, including the large gold plated terminals compatible with banana plugs for the speaker outputs, in order to preserve the purity of sound. This premain amp also features a special output jack that allows you to directly connect a subwoofer to the amp-providing the extra impact of a powerful bass, and filling your room with even more dynamic sound.

The aluminium front panel features a luxurious hairline finish, as well as an understatedly simple, elegant layout—including originally designed aluminium control knobs that reflect the top-class identity of Yamaha HiFi. This component is truly as delightful in use as it is in listening.
