Sansui AU-5900 Integrated Amplifier (Solid State) Lovely example a much sort after 70’s amplifier. 45 Watts per channel need step down Japan Condition: Excellent Payment Method: EFT, Cash on Pick up Region/State: (VIC) Victoria/Australia By Vdog 0 Comments AUD $695 Date: May 4, 2025May 4
Is A$695 the sort of money you’d pay for a clean AU-5900? Yes — that’s a fair-to-strong asking price for an excellent-condition example. Typical used AU-5900s usually land around the mid-A$600s to low-A$800s depending on service history and cosmetics, so this sits comfortably in the buy zone rather than feeling stretched.
What makes it worthwhile is the Sansui house sound: 45Wpc, a solid phono stage, and enough grip and sweetness to suit efficient speakers beautifully. The AU-5900 is also one of the more respected mid-line Sansuis from the period, so a tidy original unit has real appeal. At this price, the key upside is condition — if it’s truly clean, quiet, and unmodified, it’s a nice buy.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
