Serviced 1977 SANSUI AU-517 dual Mono Amplifier 36lbs In superb condition , clean inside and out True Dual Monoblock Direct Coupled Amplifier Design
This great looking amplifier represented my introduction to the amazing Sansui stereo components of the late 70’s. Many people consider Sansui’s equipment of this period among the best stereo equipment ever made by anyone!
Conservatively rated at 65WPC, the AU-517 was second from the “top-of-the-line” AU-717 when Sansui launched it’s now legendary X17 line of 6 integrated amplifiers in 1978.
The 1978 65WPC drove my biggest speakers at serious listening levels with the volume control at only –28dB !
While the 517 has slightly less power than the 717 the important specs tell the story:
THD is identical at 0.025%.
Intermodulation Distortion is 0.01%.
Rise time is 1.4µSec
and Slew Rate is 50V/µSec.
These are serious audiophile number and they help make this amp one of the quietest and sweetest sounding components I’ve ever heard.
Like it’s bigger brother, the 517 has two totally isolated power supplies (see pictures) driving the left and right channels. This dramatically reduces crosstalk and other forms of distortion while increasing channel separation and producing a wonderfully rich and transparent sound stage.
It would be impossible to find a new integrated amplifier to match these specs and build-quality for less than $2K today and it is unlikely you’ll find a cleaner example of this wonderful amplifier anywhere.
