Integrated DC Stereo Amplifier (1978)
The AU-517 with it's DC power amp boats highly accurate reproduction of all signals (including any kind of musical signal), and it achieves exceptionally high circuit stability. The pre-driver circuitry is so effective in assuring stable performance in the face of temperature and voltage changes that Sansui has registered it with major patent offices around the world.
The subsonic filter attenuates harmful frequencies from 16Hz and below on a 6dB / octave slope, yet keeps musical content intact.
The potentiometer for master volume control is a precision attenuator type with 32 accurately calibrated steps marked in decibels (dB). By a simple calculation you know how much average power you are feeding your speakers.
The AU-517 has full monitoring/recording/dubbing facilities for two stereo tape decks. All play/copy operations can be handled by a trio of switches and a rotary knob, permitting a number of practical uses.

Excellent amplifier. Very similar to the popular AU-717 (similar faceplates, true dual mono design, etc) but with 20 watts less per channel and simpler tone controls. Superb phono stage; no noise or hum even with the volume very high. Overall character: smooth yet detailed with well-defined bass. Highly recommended. - 10/10 by GoldSoundz
