Fighting for attention and street cred among hi-fi connoisseurs, Sansui introduced the 9090DB in 1976, hailing it as "one of the most technologically advanced amps on the market" in its sales brochure. A bold statement indeed, but this amplifier must have been special, because it could compete with models such as Pioneer's top-of-the-line SX-1250.
