Nice working integrated amp from 1975 Sansui AU-9900 nice condition 1 owner bought in military.. Spent few days with it powers up 2 sets of JBL'S nicely. UPS Double box shipping Delivery to MN IA IL IN MI WI OH
Compared with the obvious alternative at this price point—a more common mid-tier vintage integrated—the asking price is fair. At US$1,195, it lands exactly on the median of recent comparable USD listings, with the market sitting between US$1,169 and US$1,223, so this is neither a bargain nor a stretch.
What makes it worth a look is the AU-9900’s reputation as a serious late-’70s Sansui integrated: 80 watts per channel, a hefty build, and the kind of smooth, authoritative presentation that keeps these pieces in demand. If the unit is clean, unmolested, and properly serviced, this is the sort of vintage amp that rewards long-term ownership; just want confirmation that it powers up quietly, all controls behave, and no restoration shortcuts were taken.

Sansui, a pioneering Japanese audio brand, traces its origins to 1947 when it was founded in Tokyo by brothers Sakurai and Shunichi Yamamoto. Emerging from post-war Japan, the company quickly established itself as an innovator in consumer electronics, leveraging precision engineering to craft components that rivaled Western counterparts. Its heritage is rooted in the golden era of hi-fi, where Sansui's commitment to sonic purity helped define Japan's rise as a global audio powerhouse.
The brand excelled in a broad spectrum of hi-fi categories, with particular renown for its integrated amplifiers, receivers, and tuners that delivered warm, dynamic sound. Sansui also produced acclaimed speakers, turntables, cassette decks, and later digital converters, emphasizing robust build quality and innovative features like direct-coupled circuitry for low distortion. These products catered to audiophiles seeking balanced performance across analog and early digital domains.
Today, Sansui holds a cherished position in the vintage collector market, revered for its mid-to-high-end gear from the 1970s and 1980s—icons like the AU-series amps remain sought after for their musicality and reliability. While no longer a frontline manufacturer, its legacy endures among discerning buyers restoring classics or hunting timeless performers, blending nostalgia with enduring value.
