ABOUT

The Sansui QRX-9001 is the ultimate expression of Sansui’s 1970s innovation — a true quadraphonic powerhouse built for serious audiophiles.

With its bold brushed-aluminum face, dual power meters, and rich amber lighting, the QRX-9001 defines the art of analog engineering.

Fully serviced, recapped, and matrix section aligned, this unit performs flawlessly — deep, dynamic, and authentically vintage.
