Product Details

Featuring the best of our analog audio technologies, the PM-14S1 integrated amplifier provides reference class sonic performance along with the ability to handle the widest range of sources. There are multiple analog inputs and outputs, including a high quality phono processor that can accept moving magnet and moving coil signals, analog input signals remain in the analog domain all the way through to the headphone and speaker outputs. The power amplifier section delivers 90 watts per channel into 8 ohms, and 140 watts per channel into 4 ohms, and the power supply features a massive 650 VA toroidal powertransformer with oxygen free copper secondary windings, as well as high speed, high current Schottky Barrier Diodes in the rectifier stage. Our exclusive HDAM (Hyper Dynamic Amplifier Module) technologies are employed throughout, including the phono processor, line stages, power amplifier stages and the headphone output circuit. The elegant remote control can also control the matching SA-14S1 SACD player.

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.

Current Feedback

Current Feedback amplification is a well known, Marantz' original circuit technology. The Current Feedback amplifier technology fits perfectly with the high requirements set for Super Audio software providing wide-bandwidth, high-speed reproduction. The impedance at the Current Feedback point is limited resulting in a very low phase shift. Marantz receivers and amplifiers equipped with Current Feedback can keep the phase compensation via Negative FeedBack (NFB) to a minimum, resulting in high through-rate, excellent transient response and superb sonic transparency for the full bandwidth. Unlike conventional Voltage Feedback amplification, the Current Feedback amplification makes the power amplifier in-sensitive to difficult loudspeaker loads.

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.

New HDAM

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.

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.

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.

Toroidal 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.

WBT

Very high quality speaker terminals made by German speaker terminal specialist WBT who has over 20 years of experience in production of best sounding speaker terminals.
