Current Feedback

Current Feedback amplification is a well-known, Marantz-original circuit technology, thoughtfully designed to match the requirements of Super Audio hi-res music for wide-bandwidth, high-speed reproduction. The impedance at the Current Feedback point is limited, generating a very low phase shift. Marantz Current Feedback amplifiers reduce the need for phase compensation by minimizing Negative Feedback (NFB). This simplifies the signal path and results in a high through-rate, excellent transient response and superb sonic transparency across the full bandwidth. Unlike conventional Voltage Feedback topology, Current Feedback also makes the power amplifier insensitive to difficult loudspeaker loads.

Marantz HDAM Technology

Marantz developed its discrete circuit boards called Hyper-Dynamic Amplifier Modules, or HDAMs, to replace the chip-based amps used elsewhere. Using discrete surface mount components with short mirror-image left and right signal paths, HDAMs outperform the regular integrated Op-amps dramatically in Slew Rate and noise level. The result is much more dynamic, accurate and detailed sound. Over the years, Marantz has developed different HDAMs to fit the particular requirements of players and amplifiers. The PM8006 uses the high-grade SA3 version.

Marantz Musical Phono EQ

For a long time, Marantz integrated amplifiers have featured high-quality phono stages. We’ve elevated our commitment to vinyl with the Marantz Musical Phono EQ stage, as seen in the PM8006 amplifier. Enjoy the very best playback of all music sources, be they digital or analog. Marantz Musical Phono EQ uses two-stage amplification, allowing less gain per stage for lower distortion. The PM8006 combines Marantz HDAM technology with JFETs (junction gate field-effect transistors) in the input stage, providing high input impedance that eliminates the need for AC coupling capacitors and simplifies the signal path, vastly improving the signal purity overall.

Marantz rethought the re-equalization process within the phono stage, splitting it into passive and active sections for more accurate equalization. The RIAA correction is carried out within an HDAM, while amplification is in the hands of a high-quality op-amp that runs in Class A mode for minimal distortion and clean, open sound. With Marantz Musical Phono EQ there’s no need to consider upgrading the PM8006 with offboard phono stage — the amplifier already includes premium-class phono capability for optimized playback of all formats.

Toroidal Transformer

A Toroidal transformer offers several advantages that derive from its efficiency and power capability. The shape of it lends to low levels of electromagnetic radiation and mechanical vibration, producing improved sound quality over what you might experience with dated transformer models.

Often Under Estimated: High-Quality Volume Control

Newly developed electric volume control uses the latest volume control IC to realize better channel separation and dynamic range and distortion-reduction while retaining the operational feel of an analog volume control device. The amplifier employs new Marantz-designed electric volume control for high linearity and best-in-class channel separation.

High Quality, Original Marantz SPKT-1+ Speaker Terminals
The terminals are made of massive brass with a thick silver plating, providing the best possible contact with speaker cables. We’ve mounted the main speaker terminals lower, reducing the signal path and generating better speed and dynamics via High Instantaneous Current topology
