DetailsPM-15S2 Limited Edition is the epitome of extreme quality and is, quite simply, a masterpiece. In both performance and appearance, it stands out in the Premium Range, with exclusive silky-black finishing. As you would expect from such a limited edition player, it includes all the exceptional-quality components and subsystems as its thoroughbred stable mate, the PM-152. But in addition, it incorporates improved customized components and the use of a more efficient electrical signal path to elevate sound quality to even more sublime levels. The PM-15S2 Limited Edition represents a true milestone in the history of Marantz. It also represents a rare and precious opportunity to own a genuinely exclusive object of desire.
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.SPECIFICATIONSChannels
