Sansui D-11 / AU-D11 (circa 1982–1983)
Little is documented about the Sansui "D-11", and even the exact model name is a matter of record rather than certainty. What survives in period magazines identifies it as the AU-D11, an integrated amplifier in Sansui's early-1980s line. Sansui's own advertising grouped the AU-D11 with the AU-D9 as the company's Super Feedforward models. The ads claimed the circuit eliminated the last vestiges of high-level, high-frequency distortion in the output stage and put the two amplifiers in a class by themselves (HiFI-Stereo, June 1982, p.41; the same campaign ran into 1983).
The one substantial review impression that survives is unreservedly positive. Audio (February 1982, p.47) said the reviewer could imagine no improvement to the AU-D11's sound. That is about as strong an endorsement as a review can give. The same issue carried measurement data plotted with both channels driven into 8-ohm loads at 1 kHz (Audio, February 1982, p.45). It also noted a moving-coil phono input with 0.5 mV sensitivity, a moving-magnet input, and 0.5 V sensitivity for high-level inputs.
Beyond those fragments, the paper trail goes quiet. Production years, original price, and full specifications have not been confirmed in the Archive's research. The AU-D11's pairing with the AU-D9 suggests it was a serious, high-end integrated amplifier in Sansui's range, but its own power rating is not preserved in the sources available.
- Type: integrated amplifier (as identified in period press)
- Circuitry: Sansui Super Feedforward (shared with the AU-D9)
- Phono inputs: moving-magnet and moving-coil (MC sensitivity 0.5 mV)
- High-level input sensitivity: 0.5 V
