![[Product Image]](images/AU9500_00107.jpg)
The top model of the AU-9500 Series that established the Sansui's reputation as one of the best audiophile manufacturers in the world. This series included AU-3500, AU-6500, AU-7500, and AU-8500.
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 Sansuis 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.
