AU-9500

The top model of the AU-9500 Series that established the Sansui's reputation as one of the best audiophile manufacturers in the world.

The AU-9500 did not have more elaborate circuitries Sansui developed some years later; however, it was well designed and well built. The AU-9500 reproduces traditional tube like sounding image; very powerful especially in the lower frequencies. The AU-9500 was the top of the line model when Sansui's founder and perfectionist, Mr. Kosaku Kikuchi, retired in 1974. His product philosophy was "Let the products speak themselves.", and the AU-9500 was his last jewel that satisfied his highest expectation.

Prodotti top di gamma di un tempo purtroppo andato danno ancora soddisfazioni incredibili ,  anche se in quel periodo si facevano apparecchi molto esuberanti e che estremizzavano gli estremi di frequenza , Sansui con i suoi prodotti di fascia alta  andava leggermente controcorrente e anticipava i tempi, infatti troviamo apparecchi dal suono vellutato e mai affaticante e con una ottima dinamica.
