Kenwood KA-2000


The KA-2000 all transistor stereo amplifier is from Kenwood/Trio's new collection of precision-engineered units with space age solid state circuitry.

It's superior performance is the result of our engineer's many years of devoted research in the transistorized field. The KA-2000 is transformer-less from input to output terminals thus achieving playback perfection.

One of the most exciting and rewarding features is an all-new and exclusive safety circuit (US Patent) which provides complete protection for power transistors preventing damage which might otherwise result from an excessive input signal or an output terminal short.

The KA-2000 expects rugged use. It was designed and engineered to take it.


Power output: 13 watts per channel into 8Ω (stereo)

Frequency response: 20Hz to 50kHz

Total harmonic distortion: 0.5%

Damping factor: 20

Input sensitivity: 2.1mV (MM), 130mV (line)

Signal to noise ratio: 65dB (MM), 75dB (line)

Speaker load impedance: 4Ω to 16Ω

Dimensions: 260 x 105 x 237mm

Weight: 10lbs

I have been through many components over the years both in my listening room and on my repair bench. For some reason I keep coming back to the low power integrated amps both transistor and solid state.
The KA-2000 is one of my favourites from the early 70s becuase it sounds like more and is free of extra controls and technology. Warm sounding and punchy. I just finished completely recapping one and it really shines with a pair of PSB monitors. No disappointments from this vintage piece.
