About the AU517
The Sansui AU-517 integrated amplifier features a DC power amplifier design that delivers highly accurate reproduction of all signals with exceptional circuit stability. It includes a dual-FET differential power amp input to improve slew rate and reduce transient intermodulation distortion (TIM), extending frequency response. The amplifier has two independent power supplies to reduce crosstalk and distortion, providing a clear and well-defined sound stage. It offers full monitoring, recording, and dubbing facilities for two stereo tape decks, with practical play/copy operations controlled by switches and a rotary knob. The phono equalizer is designed for minimal distortion and high overload capacity, accommodating high cartridge outputs for wide dynamic range. Tone controls provide ±10 dB adjustment for bass and treble, and a subsonic filter attenuates frequencies below 16 Hz to preserve musical content. The AU-517 is praised for its smooth, clear, and detailed sound, robust power output, and longevity, making it a serious performer among vintage amplifiers.
