An excellent sounding receiver with a fat juicy tube like sound,
probably due to the .5 thd, I use it as a regular 2 channel stereo, not using the other 2 channels means more punch available from the power supply! (30,000uf) I love it ..also have a 1979 60w /ch Pioneer with a cleaner sound, both are great but I like the fatness of the Kenwood, the bass (and treble) is so analog and full, and warm....more than enough power to make you go deaf
with big speakers, too...

One of the monster Kenwood receivers of the quadraphonic era. These things weigh a ton, and are built like tanks. Unlike the smaller amps, switching to 2CH does not internally bridge the front and rear amplifiers like the 5340, 6340 and 7340 do. But with 50W RMS per channel into 8 ohms you can get some serious tinnitus with decently efficient speakers.
The two phono inputs have 100K impedance, which is to help the cartridge output the ultrasonic carrier signal into the internal KCD-2 CD-4 demodulator. If you have the opportunity to get ahold of a decent example of a KR-9940, you won't be disappointed. The MSRP was ~$950 back in 1975, and it still is worth every penny. Not as flashy as a Marantz 4100, but with the extra money you save buy a Tektronix scope and hook it to one of the recording outputs for the light show.

I meant a Marantz 4400. It doesn't look like I can update my review.
