Compact the HD-CD1 may be, but at its heart is all the technology that’s made Marantz a leader in top-quality CD playback. And central to that is the use of the Marantz-designed HDAM Hyper-Dynamic Amplifier Modules: in place of the all-in-one ‘chip amplifiers’ used elsewhere, these miniature amplifiers are built from separate, optimised components for the very best sound quality, and are found in Marantz products all the way up to the Reference series players and amplifiers. In the HD-CD1 the latest-generation HDAM-SA2 version of this technology is used, to provide a wide dynamic range and wide frequency response with lowest distortion – in other words, to get you closer to the music. HDAM technology is also used in the headphone section, which has its own dedicated amplification.Reference-quality digital-to-analogue conversion
Central to the sound quality of the HD-CD1 is a high-quality CD transport mechanism, designed for ultra-accurate disc-reading, and this sends data to the player’s high-resolution digital-to-analogue converter, which is the same Cirrus Logic CS4398 device found in top-flight digital hardware. This is used together with a crystal oscillator master clock designed for ultra-low phase noise, and a low impedance capacitor, also designed for low noise, ensuring digital data is converted into an analogue sound with lifelike dynamics and timbre, breathtaking presence and sheer musicality.Dedicated headphone amplifier with volume control and adjustable gain
Whether you want to use the HD-CD1 on your desk for full-time headphone listening, or just occasionally want to connect a pair of ‘phones for a private music session, the dedicated headphone section in the player will delight. To make the most of personal listening, it has its own volume control and a dedicated HDAM-SA2 amplifier, complete with adjustable gain setting – low, medium and high – to enable it to drive even highly-demanding audiophile headphones.Analogue and digital outputs
As well as its own high-quality analogue outputs, enabling it to be used with any amplifier including the matching HD-AMP1, the HD-CD1 has both optical and coaxial digital outputs, meaning it can be used as a CD transport straight into the digital input on the HD-AMP1 and allowing it to be used with the superb ESS Sabre DAC built into the amplifier. Like the analogue outputs, the coaxial digital connection uses a high-quality gold-plated RCA socket, and a digital cable is supplied with the player.High-current power supply and vibration-suppressing chassis
Noise is the enemy of great sound, and the HD-CD1 has extensive measures to suppress both electrical and mechanical interference. A high-current power supply with high-capacity storage capacitors is used to ensure the player is able to deliver the dynamics of music, along with high-speed Schottky Barrier Diodes. The player also has auto-standby and very low power consumption when in standby mode. The HD-CD1 is built on a double layer base-plate for rigidity and vibration suppression, aided by the use of compliant feet, a solid aluminium fascia and a rigid top-plate, and is finished with retro-style side-cheeks for that ‘classic Marantz’ look, whether in Silver Gold or Black.System remote control
The remote control handset supplied with the HD-CD1 controls all the functions of player, and can also ‘drive’ the matching HD-AMP1, for simple system integration and convenience.
