current feedback
Current Feedback amplification is a famous Marantz original circuit technology, perfectly suited to the requirements of high-resolution Super Audio music for wide-bandwidth and high-speed reproduction. The impedance at the current feedback point is limited, with a very low phase shift, which means that Marantz Current Feedback amplifiers minimize the need for compensation. fase via negative feedback (NFB). This simplified the signal path, resulting in high transmission speed.missionand, excellent transient response and superb sonic transparency across the entire bandwidth. Unlike conventional voltage feedback circuit topology, Current Feedback also allows the power amplifier to withstand the demanding loads of some loudspeakers.

Marantz HDAM topology
Marantz developed its own discrete circuit boards, called Hyper Dynamic Amplifier Modules, or HDAMs, to replace the chip-based amplifiers used elsewhere. Using discrete surface-mount components with short, mirror-image left and right signal paths, HDAMs significantly outperform conventional amplifiers. operaIntegrated circuit design improves slew rate and noise levels, resulting in much more dynamic, accurate, and detailed sound. Over the years, Marantz has developed several HDAM circuits to meet the specific needs of players and amplifiers: the PM8006 uses the premium version called SA3.

Marantz Musical Phono EQ
For a long time, Marantz integrated amplifiers have featured high-quality phono stages, but now the company is committed to reaching new heights with the Marantz Musical Phono EQ stage, launched in the PM8006 amplifier. This exclusive technology, which simplifies the signal path in the phono stage for optimal audio quality, underlines the company's commitment to reproducing all musical sources at their best, whether digital or analogue. Marantz Musical Phono EQ uses two-stage amplification, allowing lower gain for each stage, resulting in less distortion. Of course, being a Marantz design it uses our HDAM modules, in this case combined in the input stage with JFETs (junction gated field effect transistors), to have a high input impedance. This allows the previously used AC coupling capacitors to be dispensed with, to achieve a simpler signal path for the weak output level from a phono cartridge, improving signal purity.
Marantz has also revised the re-equalization process within the phono stage, a key part of vinyl record playback required to compensate for the format's limitations. In the Marantz Musical Phono EQ stage, this re-equalization is divided into passive and active sections for more accurate equalization: RIAA correction is performed within an HDAM module, while amplification is handled by a DAC. operahigh quality tional configured in modaliClass A for minimal distortion and a clean, open sound. With Marantz Musical Phono EQ, there’s no need to consider upgrading the PM8006 with an external phono stage: as part of Marantz’s commitment to optimizing playback of all formats, both digital and analog, the amplifier already has premium-class phono capabilities.

Toroidal transformer
A toroidal transformer has several advantages over a normal lamination core transformer. It is very efficient and therefore offers more power than the same size of a lamination core transformer. Furthermore, thanks to its shape, the electrromagnetic and mechanical vibration are
extremely low, allowing better sound quality.

An often overlooked aspect: high-quality volume control
A newly developed electric volume control using a next-generation integrated circuit for volume control, allows for improved channel separation, dynamic range and distortion reduction, while maintaining the feel operaThe amplifier uses a new Marantz-designed electric volume control for high linearity and improved channel separation, ensuring the most immersive music experience.

High quality Marantz SPKT-1+ speaker terminals
The speaker terminals are made of solid brass with a thick silver plating to achieve the best possible contact with the speaker wires. Additionally, the main speaker terminals are mounted lower, and therefore closer to the main circuitry, to reduce the signal path. This is in line with the entire amplifier design, which uses the shortest possible signal path and High Instantaneous Current topology for improved speed and dynamics.
