Remarks

  • Sansui mid-range model of the early 1980s (1981-84). Provides two times 50 watts of output power into 8 ohms. Few distortions thanks to Sansui's Super Feedforward system. Input source selectable by push-switch, LEDs indicate active input source. In the UK often sold as a set with KEF Coda III speakers.

AU-D33 was one of the best amplifiers from Sansui and from the market in that period.
