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.

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.
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 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.
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.
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.
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.
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.

Buying a Marantz Factory Refurbished product is a great way to get "as-new" products at a considerable savings. Every product has been thoroughly tested, repaired (if necessary), cleaned and otherwise renewed to original condition. Next it's repackaged with original accessories included. When you consider that a factory-renewed Marantz product undergoes such close scrutiny for defects and workmanship, you might actually be buying something that is in many ways better than new. And for your piece of mind and protection, your purchase is covered by a full 1 year parts and labor warranty valid at any authorized Marantz repair center (you can look-up locations online here or call 800-654-6633)
Marantz, like all electronics manufactures, receives products returned for various reasons. In 2023 consumers returned 23 billion dollars in electronics globally, of which less than 5% were found to be defective! Once a product has been opened, it must be resold as refurbished or open box and cannot be resold as new again. The history and reason why a product was returned is not provided to us, thus we cannot provide any additional details regarding its past. All products are processed by Marantz certified technicians, where they are fully tested, repaired (only if necessary), and retested again to ensure the highest quality control. Each unit must pass a complete battery of test before it can be titled a "Marantz Factory Refurbished" product.
Most (not all) units are cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10). Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked displays, broken knobs, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we cannot provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.
