Experience the authority and refinement of true 1970s Hi-Fi engineering with this outstanding Technics SU-9400 integrated amplifier, a powerful and beautifully built centerpiece from the golden era of Japanese audio manufacturing.
Designed and manufactured in Japan circa 1975–1977, the SU-9400 reflects Technics’ commitment to precision circuitry, robust construction, and clean industrial aesthetics that remain timeless today.
Delivering approximately 80 watts per channel into 8 ohms, this amplifier provides confident drive, dynamic headroom, and impressive control across a wide range of loudspeakers.
Its discrete transistor amplifier design ensures stable output performance with low distortion, maintaining clarity even at higher listening levels.
Total harmonic distortion is rated at approximately 0.05%, preserving musical detail and ensuring transparent signal reproduction.
The frequency response extends roughly from 10 Hz to 40 kHz, offering deep bass extension and refined high-frequency resolution beyond the audible range.
Signal-to-noise ratio reaches approximately 90 dB (line input), supporting quiet backgrounds and excellent channel separation.
The phono stage supports MM cartridges, making it an ideal partner for high-quality vintage turntables and analog vinyl systems.
Connectivity includes multiple line inputs, phono input, tape monitor loop, speaker A/B switching, and robust rear-panel terminals for secure connections.
Physical dimensions measure approximately 430 x 149 x 365 mm, providing a commanding full-width Hi-Fi presence in any classic audio rack.
With a substantial weight of approximately 11–12 kg, the heavy transformer and solid chassis construction confirm the serious build quality of mid-1970s Japanese engineering.
