The Model 50 is an integrated amplifier from Marantz, built around the brand's Custom HDAM circuit topology. The Model 50 revives a model number from the company's history.
Position in line
Within Marantz's integrated amplifier range, its proprietary HDAM circuitry is used in place of off-the-shelf operational amplifiers.
Key specs that matter
Rated output is 70 W into 8 ohms, rising to 100 W into 4 ohms. Rated bandwidth is 5 Hz to 100 kHz. Signal-to-noise is 116 dB with distortion at 0.02%. Damping factor is 100. The chassis measures 442 x 431 x 130 mm and weighs 14.2 kg.
Pairing
Six single-ended inputs cover a substantial source lineup without needing external switching.
Alternatives
The Model 40n sits nearby in Marantz's range with added streaming, while the PM6007 sits below this model at a more accessible tier.
