Marantz PM11s3 Premium Series Integrated Amplifier


Out of stock

This highly admired Premium amplifier is now in its third generation and is quite simply better than ever. That?s because we added new Marantz original high-quality, high-purity copper speaker terminals.
  • 3 Stage Circuit
  • Copper Plated Chassis
  • Linear Volume Control
  • Super Ring Transformer

There?s also a new power amp direct input, and a new?Marantz?Remote App operation (iOS and Android) via the?Marantz?control bus with Network player. These additions, and the many?refinements?we have made, not only improve the audio quality and functionality of what was already a?seriously impressive amp?but also ensure its success will continue for long into the future.

Even before these refinements, the PM-11 was packed with?advanced technologies?to give you the?best in detail, precision, and emotion. The shielded?Toroidal?transformer and?customised?components, ensure?ultrastable?power output at 2x?100W?into 8 ohms or?2x?200W?into 4 ohms.

Absolute signal integrity and very high signal-to-noise ratio is guaranteed via the?3-stage construction which includes a pre-amplifier and a dual-stage main-amplifier, as well an extra pre-amplifier for?Phono?MM/MC. Key technologies include the latest?Marantz?Current Feedback HDAM?SA3, as well as symmetrical circuitry with the shortest signal paths to deliver?dynamic sound and perfect stereo imaging. The result is an unbelievably wide sound stage, but with extremely precise positioning of instruments and vocals. In addition, the chassis and rear panel are copper-plated to guarantee low impedance ground potential at any point for best possible signal integrity. All of which means that the?PM-11S3?is a?reflection of superiority.

3 Stage Circuit

The 2-stage amplification concept for main amplifiers or the 3-stage one for integrated amplifiers offers an extremely wide frequency range needed for the high resolution formats like SA-CD and DVD-A. In addition it influences the overall performance in relation to speed and accuracy. The first amplification stage is built into the pre amplifier followed by voltage amplification and the 3rd and final is the power output stage to guarantee high current output driving speakers more vividly and dynamically.

Choke Input

In the power supply section, the choke input topology is adopted to drastically reduce rectifier harmonic noise and to reduce the influence of distortion from the mains power network. This system is especially suitable for a control amplifier in which very small signal amplification occurs.

Copper Plated Chassis

A copper plated chassis provides the best shielding against noise or electromagnetic distortion radiating from other components in the equipment. It prevents this noise from being amplified together with the audio signal. And even more important, it gives equal low impedance ground level to every point of the chassis, keeping the ground potential as clean as possible.


Marantz developed its own discrete circuit boards to replace standard IC’s. These HDAM’s consists of discrete surface mount components with short mirror image L/R signal paths. Those devices are doing exactly the same thing as the Op-Amps, but outperform the regular IC Op-amps dramatically in terms of the Slew Rate and reduced noise level, resulting in a much more dynamic, accurate and detailed sound. Over the years Marantz developed different types of the HDAM to improve quality and to fit to the special requirements of a product category like CD or amplifier.

Linear Volume Control

Linear volume control offers minimal cross talk with a very precise volume adjustment over a range from 0dB to 100dB with a gang error less than +/- 0.5dB.

Shottky Diodes

A Shottky diode is a special type of diode with a very low forward-voltage drop compared to normal diodes. This lower voltage drop translates into higher system efficiency. Shottky diodes have very fast signal handling, can easily stay higher temperatures and are sensitive very low voltages.

Super Ring Transformer

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. At a Super Ring transformer the

Symmetrical Circuit Layout

To achieve the best possible sonic performance, signal paths need to be short, direct and mirror imaged. The construction of our circuitry provides improved stereo imaging by ensuring close to perfect symmetry between right and left channel layout.
