Marantz has a consistent concept for its CD players: to reproduce music beautifully as music and to satisfy the hearts and minds of people who value music. The Marantz CD-95 is the culmination of the technology and know-how of CD developers and has achieved a high level of perfection as a music reproduction device.
The Marantz CD-95 is based on a combination of the latest "A version" S-1 type TDA1541 D/A converter and the Philips CDM-1 drive mechanism. The Marantz CD-95 is the latest product from the Philips Marantz Group, the developers of the CD, and the experts in the essence of the CD, whose sound policy is consistently focused on reproducing musicality.
The Definitive D/A Converter A version S-1 TDA1541
The D/A conversion circuit, the brain of the CD player, consists of the original LSI Philips TDA1541A S-1, which has been independently developed and improved by the Philips Marantz Group. The Philips TDA1541A S-1 is the latest Philips A version" of Philips' latest devise, the Philips TDA1541A S-1. The accuracy of a D/A converter depends on the linearity of the micro-signal and its conversion capability. Over the entire temperature range, 0.5 LSB at micro signals and 1 LSB at normal levels are guaranteed. The result is the natural beauty of musical resonance.

Groundbreaking Push-Pull D/A conversion method
The Marantz CD-95 is equipped with two D/A converters per channel. The two converters are combined in a forward and reverse phase, and the waveforms are synthesized through these converters. At the same time, in-phase components are cancelled, and even-order low distortion, including hum and ultra-low-frequency noise, is canceled and greatly reduced. The push-pull D/A conversion method has been refined over many years.
The push-pull D/A conversion method is the latest technology that Marantz's audio sense, refined over many years, has arrived at, and has succeeded in eliminating harmful components that cause sound quality degradation.
Moreover, all LSIs are "A version" S-1 type. The synergistic effect of the device and technology has dramatically improved the sound quality of CDs.
Ideal CD drive Automatic Servo Switching
CD singles are long awaited by music fans and CD collectors alike, and the Marantz CD-95 has taken new measures to maximize the potential of CD singles. The Marantz CD-95 uses a sensor to detect the disc, then switches the servo operation range according to the circuit constants, and sets the operation point to the midpoint.
The Marantz CD-95 first detects the disc using a sensor, then switches the range of servo operation according to the circuit constants, and sets the operating point to the midpoint. Of course, all switching is automatic, so the mechanism always provides the best operating conditions for both CDs and CD singles.
The Ultimate CD Drive Mechanism Philips CDM-1
The CD drive mechanism is the Philips CDM-1 type developed by the Philips Marantz Group. The basic structure was completed in 1983, and has been the foundation of representative products from the Philips LHH2000, the highest peak of professional machines, to the Philips LHH1000, the latest model. The swing-arm pickup with 1-beam system was born from a completely different idea from the usual linear tracking system. The lens is made of Rodenstock glass, which has low aberration and excellent temperature characteristics.
The pickup has excellent temperature characteristics, and its ability to pick up information is extraordinary. The linear motor that powers the pickup is a samarium-cobalt magnet with the strongest magnetic force. A powerful servo system controls the swing arm for smooth and reliable pit tracing. In addition, the swing arm itself has improved rigidity, and the die-cast base makes it virtually unaffected by external vibrations, disc scratches, and dirt.
Power supply as powerful as a high output power amplifier
The power supply circuit is the heart that gives energy to the reproduced sound. A large power transformer comparable to that of a high-output power amplifier and high-capacity (68,000/Fx2), high-quality custom electrolytic capacitors are used. The electrolytic capacitors, in particular, are carefully selected for their high sound quality using new materials. The power of the low-frequency range, such as the bass drum The results are evident in the sense of power in the low frequency range, for example, in the textured resonance of the bass drums. In the power transformer, the secondary winding is divided into separate windings for digital, audio, and display circuits to ensure independence. The regulator circuits are also discrete, eliminating noise associated with the power supply to the utmost limit.
Highly integrated anti-vibration measures, Die-cast chassis
Where there is vibration, there is noise. The Marantz CD-95's mechanism itself is vibration-resistant, and the base that supports it also features perfect anti-vibration measures. The construction is a solid sandwich structure consisting of a die-cast shirge, die-cast side panels, and a 3mm-thick bottom plate, achieving perfect vibration-free and resonance-free operation.
The top cover uses Marantz's original ARC (Aluminum Raft Ceiling) construction. The three-piece raft-cut structure increases strength and diffuses vibration modes. In addition, the preamplifier for the laser signal, which is normally mounted inside the mechanism, is isolated from the rotating system, free from the effects of vibration. In addition to vibration isolation, the circuit layout is designed to prevent interference, which can be detrimental to sound quality. Digital circuits, audio circuits, and servo circuits are isolated from the rotating system.
The digital, audio, servo, microcontroller, and display circuits are each configured as independent circuit boards to shut out noise.
