Vintage Sansui A-80 Integrated Amplifier & Insignia KEF-clone Speakers - $100 (East Montpelier)
QR Code Link to This Post
Description
In the Sansui A-80, DC-Servo means sound that's pure as pure can be these days. All stages inside the power amplifier are direct coupled. All capacitors in the signal path are eliminated. We've added nothing, thus lost nothing.
There are no capacitors used that can add harmful colouration to music. No wonder sound is exceptionally clean in the A-80. The DC-Servo controls ultra-low-frequency signals (all those below 1 Hz) so that they can't reach your speakers. Which means you can, if you have to, play warped records and still hear good sound.
Power output is a comfortable 65 watts per channel both channels driven into 8 ohms, all this from an OCL (Output Capacitor-less) true complementary circuit with a DC-Servo system, built around a dependable op-amp (operational-amp) IC, for good, clean, dependable performance.
