About This Model

The Marantz PM420 is a stereo integrated amplifier from 1982, delivering 40 watts per channel into 8Ω with a minimum speaker load impedance of 4Ω. It features a built-in MM phono stage alongside line-level inputs, making it a versatile single-box solution for both turntable and source-based systems. Total harmonic distortion is rated at just 0.05%, with a frequency response spanning 10Hz to 30kHz and a signal-to-noise ratio of 90dB on line inputs — figures that reflect Marantz's commitment to clean, accurate amplification in this era. A damping factor of 50 provides solid control over speaker drivers, contributing to the composed, well-defined sound character these late-Marantz Japanese-era integrateds are known for.

A great opportunity to own a Marantz PM420 at this price point.
