From Sansui:

Sansui is proud to introduce the new AU-717 DC integrated amplifier and matching TU-717 tuner, designed for your greatest listening pleasure. We are proud of the superlative specifications that our sophisticated research has achieved. The finest available at any price.

The TU-717 is a high technology AM/FM stereo tuner made to match the most sophisticated amplifier.

It features a sensitive front end and a dual bandwidth IF section with selector switch for either lowest distortion or highest selectivity.

The AU-717 amplifier incorporates an advanced design feature which has extremely low inherent transient intermodulation distortion enabling negative feedback (necessary in traditional amplifier design but undesirable) to be reduced to the absolute minimum.

Power amplifier design too, shows a departure from tradition resulting in the elimination of DC drift.

Differential push/pull amplifier stage eliminates open-loop distortion. The driver stage is 3-stage darlington connected.
