ABOUT THIS ITEM

The Sansui AU-9500 is a flagship integrated amplifier made in Japan by Sansui, one of the most respected names in vintage audio, produced from 1971 to 1975 and widely regarded as one of the greatest vintage integrated amplifiers of the 1970s — the finest and most advanced of the entire AU series. It delivers 75 watts per channel into 8 ohms (115 watts into 4 ohms) with very low total harmonic distortion of just 0.1%. The power amplifier uses an all-stage, direct-coupled OCL, pure-complementary parallel push-pull circuit with eight power transistors for powerful, clean, and natural sound. A standout feature is Sansui's Triple Tone Control (T.T.C.): unlike ordinary amplifiers with fixed tone circuits, it provides independent Bass, Midrange, and Treble controls, each with three selectable turnover frequencies, for precise tailoring of tonal balance without sacrificing musicality. It offers two phono inputs, a microphone input, high and low filters, a loudness control, tape-to-tape dubbing, and connections for a quadraphonic decoder and a Dolby unit. Built like a tank at 23.3 kg with classic Sansui styling, the AU-9500 remains a legendary and highly sought-after vintage integrated amplifier.

・Power Supply Voltage: AC 100V, 50/60 Hz (Japanese domestic model). Please use a suitable step-down transformer in 110–240V regions.
