Kenwood KA-9300 (1979)

The KA-9300 is 430 mm wide and clad in silver. It was Kenwood's top-tier integrated amplifier when it launched.

Overview

The Kenwood KA-9300 came out in 1979 as a flagship stereo integrated amplifier. It was sold under both the Kenwood and Trio names, and shows up in listings as "Trio/Kenwood KA-9300" or even "Supreme 600". It is a solid-state design that delivers 120 watts per channel into 8 ohms. Some sources list a continuous output of 2x 130W RMS under test conditions. The front panel is typical of late-1970s high-end gear, with clearly laid out inputs and controls. The silver finish and heavy chassis mark it as a premium unit.

The KA-9300 is called a "top model amplifier," but detailed technical documentation on its internal architecture is scarce. The connections are better documented. It has line and DIN inputs with sensitivities of 150mV/80kΩ and 80mV/150kΩ respectively. It also has speaker outputs labeled Direct, A, and B. It was made in Japan. At 430 x 149 x 376 mm, it is slightly more compact than many of its contemporaries, though still substantial on a rack.

Collectibility & Value

The KA-9300 is still sought after by collectors of vintage Japanese audio, though verified market data is limited. A used unit was listed for C$955.02 on Reverb, and another appeared for sale. An upgrade kit exists to replace the original speaker terminals, which were designed for older connector types, with modern binding posts. No widespread reports of inherent failures or maintenance issues have been documented. Detailed service records and common fault patterns are also missing, so buyers should inspect units carefully.
