Your next step into Marantz HiFi Featuring an upgraded, high-quality DAC, digital inputs and a newly revamped built-in phono equalizer, the Marantz PM6007 integrated amplifier features ample connectivity and creates a realistic listening experience for the most musical sound. Current Feedback Amplifier 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 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. Reference Quality D/A Conversion For Digital Input 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. High Current Power Supply 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. Toroidal Transformer 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.
