Powered by a Toroidal power transformer and customized block capacitors, the PM6007 integrated amplifier delivers 45 watts (8ohm, 20Hz-20kHz) of power-per-channel. You can easily connect both analogue and digital sources or connect your turntable to the built-in phono pre-amplifier. Listen to your favourite Hi-Res audio content through the 192-kHz/24-bit D/A converter and experience enhanced bass with a subwoofer-out option. The PM6007 features a new Hi-Res D/A conversion.

It is equipped with a reference class AK4490 D/A converter, which provides up to 192-kHz/24-bit resolution for optimum fidelity with your Hi-Res audio file types. The power supply supports high current, high speed Shottky Barrier Diodes and high current storage capacitors fed by a Toroidal Transformer that together provide wide dynamic range and low impedance drive capability. A Toroidal Transformer has several advantages over a normal EI core transformer. The highly efficient design delivers more power compared to the same size EI core transformer.

In addition, the shape of the Toroidal Transformer delivers low electromagnetic radiation and mechanical vibration for better sound quality. Marantz has developed our own discrete circuit boards to replace standard IC's. These HDAM's (Hyper Dynamic Amplifier Module) consist of discrete surface mount components with short mirror image L/R signal paths. These devices do exactly the same thing as the Op-amps, but outperform these solutions dramatically in terms of the Slew Rate and reduced noise level, resulting in more dynamic, accurate and detailed sound.

In the PM6007, the HDAM-SA3 circuit improves on its previous module and the idling current stability is less influenced by power transistor temperatures to maintain sound performance even at high level output. The Current Feedback Amplifier technology provides wide-bandwidth and high-speed sound reproduction. In combination with the high current power supply, the PM6007's amplifier section holds a large energy reserve to easily drive even the most demanding speakers. An advanced thermal compensation avoids memory distortion for clean amplification under any circumstances.
