With a fully discrete current feedback design, the PM8006 integrated amplifier is perfect for audiophiles wanting both excellent music quality and flexible
operation. It offers a powerful 2x 70W into 8 ohm, while the symmetrical circuits ensure optimal imaging. To ensure the most involving musical experience,
the amplifier uses a new Marantz-designed electric volume control for high linearity and best-in-class channel separation and to make the most of vinyl replay
there’s the brand-new Marantz Musical Phono EQ phono preamp stage, designed to get the purest signal from beloved vinyls by minimized noise levels.
Current Feedback amplification is a well-known, Marantz-original circuit technology, suiting perfectly with the requirements of Super Audio hi-res music for wide-bandwidth, high-speed reproduction. The impedance at the Current Feedback point is limited resulting in a very low phase shift, meaning Marantz Current Feedback amplifiers reduce the need for phase compensation via Negative FeedBack (NFB) to a minimum. This simplified the signal path, resulting in 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 own 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, resulting in a 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, but now the company takes its commitment to vinyl to new levels with the Marantz Musical Phono EQ stage, launched in the PM8006 amplifier. This unique technology, simplifying the signal path in the phono stage for optimal sound quality, underlines the company’s commitment to the very best playback of all music sources, be they digital or analogue. Marantz Musical Phono EQ uses two-stage amplification, allowing less gain per stage, for lower distortion. Of course, being a Marantz design it uses the company’s HDAMs, but here they’re combined with JFETs (junction gate field-effect transistors) in the input stage, giving a high input impedance. This allows the deletion of the AC coupling capacitors previously used providing a simpler signal path for the tiny output from a phono cartridge, improving signal purity.
Marantz has also rethought the re-equalization process within the phono stage, a fundamental part of vinyl replay required to compensate for the limitations of the format. In the Marantz Musical Phono EQ stage this re-equalization is split into passive and active sections, for more accurate equalisation: the RIAA correction is carried out within an HDAM, while amplification is in the hands of a high-quality op-amp, running in Class A mode for minimal distortion, and delivering a clean and open sound. With Marantz Musical Phono EQ there’s no need to consider upgrading the PM8006 with offboard phono stage: as part of Marantz’s commitment to optimising playback of all format, be they digital or analog, the amplifier already has premium-class phono capability built-in.
A Toroidal transformer has several advantages over a normal EI core transformer. It is very efficient and therefore delivers more power compared to the same size of an EI core transformer. In addition, due to its shape, the electromagnetic radiation and the mechanical vibration are extremely low all ending in a better sound quality.
Often under-estimated: a high-quality volume control
A newly developed electric volume control using the latest volume control IC realizes better channel separation, dynamic range and distortion-reduction, while retaining the operational feel of an analogue volume control device. To ensure the most involving musical experience, the amplifier uses a 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 for the best possible contact with the speaker cables, and the main speaker terminals are mounted lower, and thus closer to the main circuit board, to reduce the signal path. That’s in keeping with the entire design of the amplifier, which uses the shortest possible signal paths and High Instantaneous Current topology for better speed and dynamics.
