Marantz PM6007 Integrated Amplifier: HDAM with improved power supply and AK4490 DAC on board
Marantz has revealed information about the PM6007 integrated amplifier, one of two models with the index 6007. The other is the CD6007 CD player. The parameters and similar design indicate that the PM6007 amplifier has come to replace the popular 6006 model.
The amplifier features Marantz’s proprietary HDAM-SA3 (Hyper Dynamic Amplifier Module on discrete elements) circuitry with current feedback, aimed at an extended dynamic range with reduced distortion. The PM6007 will deliver 45 watts of RMS power to 8 ohm speakers, covering the standard audible frequency range.
It has improved heat dissipation to improve efficiency at high volume levels, especially when playing bass. The toroidal transformer is complemented by increased filtering capacitors. The PM6007 has five analog inputs with gold-plated RCA connectors, including an MM phono input. Its initial stages are made on field-effect transistors. Analog capabilities are complemented by digital switching – there is one coaxial input and two optical.
The fully shielded AK4490 DAC, which provides up to 24-bit/192kHz resolution, replaces the 6006’s Cirrus Logic CS4398. The digital part was supplemented with the function of the digital filter mode. In addition to the stereo line-out, the PM6007 has a separate subwoofer output and headphone output. The Marantz PM6007 in black and silver-gold will be available on September 7 for 550 euro.
