The Sansui AU-777 is an incredible vintage amplifier that would be a feather in the cap of any audiophile's setup. Sansui is known for their quality vintage equipment, and the AU-777 is known for its insane audio quality. It features SEPP ITL circuitry, which overcomes the problem of the solid-state amplifier where the distortion tends to be somewhat higher at low power levels. It also has the widest possible power bandwidth, double protective devices for power transistors, and not one but two phono inputs for your turntables. It's a compact amplifier, but it's enough to drool over!
Unfortunately, this particular system currently works but hums, so for the right person who wants to give this amazing system the service and care it needs, it can become the perfect vintage amp!
