Stereophonic Receiver (1975-76)
The KR-9400 is the most powerful stereo receiver Kenwood has ever built, delivering a minimum of 120 watts of continuous power per channel into 8 ohm speakers, both channels driven, 20 Hz to 20 kHz, with no more than 0.1% total harmonic distortion.
The precision equalizer phono preamplifier section of the KR-9400 uses low-noise metal encapsulated transistors to deliver an exceptionally high signal to noise ratio and assure utmost circuit reliability.
The KR-9400 provides extremely high FM stereo separation throughout the audio spectrum, thanks to a newly developed phase lock loop IC circuit incorporated in the stereo FM decoder section, achieving more than 45dB separation at 1 kHz; better than 35dB at all frequencies from 30Hz to 10kHz.
A cool-running power transformer and massive heat sinks form the heart of a dual positive-negative power supply to the high-output transistor stages. This no-compromise design assures safe, cool operation even under continuous full-power output.

I've had my KR-9400 since 1979, and pretty much use it everyday. I've heard a lot of stereos in my life, but I still think my Kenwood sounds the best. It still can flex my windows at volume 7, and I'm sure I could break them at volume 9 with my pair of Jensen CS 315's.
