Marantz – PM8006 Integrated Amplifier

Made in Marantz’s Reference Factory, Built for Exceptional Playback and Power: High-Value PM8006 Integrated Amplifier Boasts HDAM Circuitry, MM Phono Preamplifier with Musical Phono EQ

Touting expert engineering and exceptional sonics, the Marantz PM8006 means you don’t have to compromise to get what you deserve in a modestly priced high-end integrated amplifier. Built in Marantz’s Reference Japanese factory, this 27-pound instrument actually sounds twice as powerful as its 70Wpc into eight ohms (100Wpc into four ohms) rating due to the high-current capabilities of its all-discrete amplification technology. Proprietary HDAM circuits contributes to detailed playback, a new two-stage MM phono preamplifier with Marantz Musical Phono EQ helps revive the life of older LPs, and an electric volume control yields enhanced channel separation. You’ll find few, if any, better values than what this unit offers for the money in terms of blacker backgrounds, expansive dynamics, transient response, natural tones, textural reproduction, and high-power drive.

PM8006 also arrives prepared to play your high-resolution music with the emotionally engaging fidelity you demand. Marantz’s onboard current-feedback amplification circuitry simplifies the signal path and translates into wide-bandwidth, high-speed reproduction as well as stellar transparency. Not to be overlooked, a double-shielded toroidal transformer lends to quiet operation and the kind of power handling you find in larger, costlier amplifiers. Audiophile-grade SPKT-1+ speaker terminals, a triple-layer bottom plate to drastically reduce vibration and ensure stability, an aluminum extrusion heat sink, and a Tri-Tone control system that lets you fine-tune PM8006 to your heart’s content also come standard and add to the extraordinary prowess of this instrument. Marantz’s three-year parts-and-labor warranty and Music Direct’s 100% Satisfaction Guarantee put it over the top.

“Offering great performance at the price, ND8006/PM8006 streamer/integrated amplifier combination plays pretty much any music format from any source.”

A Superior Phono Preamplifier: Marantz Musical Phono EQ
Marantz Musical Phono EQ uses two-stage amplification, allowing less gain per stage for lower distortion. 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. Marantz also rethought the re-equalization process within the phonostage, 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.

Stellar Channel Separation Via the High-Grade Volume Control and Toroidal Transformer
PM8006’s newly developed electric volume control uses the latest volume control IC to realize better channel separation, dynamic range, and distortion reduction all the while retaining the operational feel of an analog volume control device. It achieves also high linearity. In addition, the toroidal transformer offers several advantages that derive from its efficiency and power capability. Its shape lends to low levels of electromagnetic radiation and mechanical vibration, producing improved sound quality over what you might experience with dated transformer models.

Ready for High-Resolution Music: Current Feedback Amplification
Current-feedback amplification is a Marantz-original circuit technology, thoughtfully designed to match the requirements of high-resolution music for wide-bandwidth, high-speed reproduction. 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 makes the power amplifier insensitive to difficult loudspeaker loads.

Proprietary HDAM Technology for Dynamic, Detailed Sound
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 in slew rate and noise level. You’ll experience much more dynamic, accurate, and detailed sound. Marantz has developed different HDAMs to fit the particular requirements of players and amplifiers. PM8006 uses the high-grade SA3 version.

High-Quality Marantz SPKT-1+ Speaker Terminals
PM8006’s terminals are made of massive brass with a thick silver plating, providing the best possible contact with speaker cables. The main speaker terminals are mounted low, reducing the signal path and generating better speed and dynamics via high instantaneous current topology.
