The Sansui AU-7900 was the next model down from the AU-9900 and AU11000 high end integrated amps in Sansui's AU range of the mid-1970's. It was replaced in 1977 by the very popular (especially in the USA) AU-717. The standard of finish is superior to it's successor with all the front panel switches made of metal and the volume control, tone controls and input selector, etc. machined from aluminium. It also has a more comprehensive set of facilities than the 717 some of which are very useful (e.g. built-in MC head amp and mono switch) while others are pointless (e.g. loudness switch, midrange tone control, high filter). It also differs from the AU-717 in that the finish of the front panel is black anodised rather than matt black paint. It also lacks the 717's optional rack mount handles.

The AU-7900, like some other Sansui amplifiers of the 1970's is a very good choice for the vinyl enthusiast, as not only does it have a good quality built-in moving coil head amp, but it also allows the pickup load impedance to be selected from a choice of 30, 50 or 100KOhms via a three-way switch on the rear panel. Also, two turntable inputs are provided.
