Sansui 9090DB Dolby Stereo Receiver – 125 Watts Per Channel – Legendary Vintage Hi-Fi Powerhouse

THE LEGENDARY SANSUI 9090DB – POWER, PERFORMANCE & DOLBY TECHNOLOGY

The Sansui 9090DB is one of the most desirable receivers from the golden age of Japanese hi-fi. Introduced in the mid-1970s, this flagship-level receiver combines serious amplifier power, an exceptional AM/FM tuner, and built-in Dolby noise-reduction technology.

Delivering an impressive 125 watts per channel RMS into 8 ohms, with both channels driven from 20Hz to 20kHz, the 9090DB has the power and control to drive demanding speakers while delivering the rich, detailed sound vintage Sansui equipment is famous for.

What makes the 9090DB especially desirable is its built-in Dolby noise-reduction circuitry. Unlike the standard Sansui 9090, the 9090DB can decode compatible Dolby FM broadcasts and encode and decode compatible tape recordings, helping reduce unwanted background noise and hiss.

The front panel is unmistakably Sansui: illuminated analog tuning display, large dual power meters that also serve as Dolby calibration meters, separate tuning and signal-strength meters, and an extensive array of audio controls.

This is a receiver built for serious collectors and music lovers who appreciate the engineering, craftsmanship, and unmistakable character of vintage Sansui.
