The Sansui G-5700 is one of those ‘in-between’ receivers that was made during the transition from analog to digital readouts. It has both a traditional analog dial as well as a digital tuner display. Built from 1979 until 1980 it produces 75 watts per channel into 8 ohms and total harmonic distortion of 0.03%.

The G-5700 has the characteristic Sansui large Volume and Tuning knobs set symmetrically in the center of the face plate. It also utilizes the square buttons used on earlier Sansui models. The dual analog/digital displays make it a little strange looking, but the backlit logo and model number at the left of the receiver is a nice touch.

The G-5700 has plenty of power for most speakers and a great tuner section as well. Overall, the sound from Sansui’s Pure Power DC stereos is very good. The volume control is aggressive. Just a minor turn of the knob and the volume will increase dramatically. I’ve found this to be an issue with other Sansui models as well.
