CDA-44040
At US$899, this is well above the typical used range for a QR-4500, which usually lands around US$100–US$150 for an average sale and about US$399.95 for a serviced, well-documented example. That makes the ask ambitious unless this unit has exceptional provenance, a recent full rebuild, or unusually complete accessories.
The upside is real: the QR-4500 is an uncommon early Sansui quad receiver, rated at 27 watts x 4 and prized for its classic matrix-quad sound and period-correct build quality. If it’s clean, fully functional, and comes with manuals or original paperwork, it’s a strong collector piece—but at this price I’d want proof of service, fresh photos of the outputs and controls, and confirmation that all four channels are healthy before committing.
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.
