Marantz PM8006 Integrated Amplifier with Phono-EQ

Description

With a fully
discrete current feedback design, the PM8006 integrated amplifier is perfect
for audiophiles who require both excellent music quality and flexible
operation. The PM8006 offers a powerful 2x 70W into 8 ohm build, while the
symmetrical circuits provide optimal imaging. To ensure the most immersive
musical experience, the amplifier uses new Marantz-designed electric volume
control and Marantz Musical Phono EQ preamp stage, created to obtain the purest
signal from beloved vinyl by minimizing noise levels. To further remove
interference, new isolating feet are used to support the amplifier, combining
high density and a damping fiber.

The PM8006 also includes preamp outputs along with a power
amp direct input, allowing you to use the unit as a standalone power amplifier
for integration into a multi-channel home theater system. For precise sound
tailoring, our triple tone control system provides separate controls for the
bass, midrange and treble. The elegant remote control features an ergonomic
layout for easy operation, and can control accompanying source players.

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 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. 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.
