Brand: Sansui

The Sansui AU-9900 is a high-end audio integrated amplifier that was introduced by the Japanese brand Sansui in the late 1970s. It has a power output of 100 watts per channel (into 8Ω) and features a robust design, with a solid aluminum front panel and chassis. Its amplifier stage is based on the JRC4580 OP-amp, which is regarded as one of the best op-amps of its time. The AU-9900 also includes a phono input stage for connecting a turntable, and it uses high-quality transformers made by Ludorff for both the input and output stages, which contribute to its rich and detailed sound signature. The amplifier's preamp section offers inputs labeled as "CD," "AUX," and "AUX 2," and has a sophisticated tone control network that allows for precise bass, mid, and treble adjustments. The Sansui AU-9900 is considered a classic by many audiophiles and is still highly regarded today for its sound quality and build quality.
