HDAM-SA2 modules make standard counted sound feel as incredible as high-resolution audio. This new amp also gives you the unique Marantz Musical Digital Filtering (MMDF), with two selectable filter characteristics to cater for different tastes and music. Each handles even the minutest of detail with loving care within the digital audio signal. As today’s new media not only comes in 44.1kHz/16 bit resolution – similar to the CD format, Marantz developed the digital section to handle signals of up to 384kHz/32bit resolution and DSD 2.8MHz / 5.6MHz / 11.2MHz. Optical and coaxial digital inputs are ready to connect a TV or set-top box, and there is a USB-B port to stream music directly from your PC or MAC. iDevices can also be connected via the USB port on the front. To safeguard quality when connected to a computer, we built extended isolation around the USB-B input to eliminate the chance of high frequency noise generated by the computer entering the HD-AMP1. Information on volume, input, resolution, and more is shown on the stylish Marantz Porthole Display. While the solid aluminum front is supported by a double layer bottom plate and retro-style side panels. Welcome to the world of compact ecstasy.
Marantz MusicLink Series
Marantz again amplifies its dedication to pure musical performance with the rebirth of MusicLink, a product series launched in 1990 with the focus on reproducing the music essentials from small-size, rarely-seen design components. The aim is simple: to bring the listener all the emotion and musical detail of the original sound studio, combined with an elegant appearance and luxuriant feel. It is not a coincidence that the creator of the delightful new MusicLink Series is once again Ken Ishiwata.
Unique Marantz audio performance with audiophile D/A Converter
Don’t get misguided by the compact form factor. The HD-AMP1 delivers 2x 70 W into 4 Ohms, playfully handling even demanding music parts thanks to an ultra-stable power supply and Marantz own Current Feedback technology. The Dual Crystal Clock and a discrete DAC post filter with the company’s highly-acclaimed HDAM pre-amplifier modules make standard counted sound feel as incredible as high-resolution audio. A high-current audiophile SABRE D/A-Converter with no less than 384kHz/32bit processing capability is able to reproduce even the smallest details with ease.
Marantz Musical Digital Filtering
The HD-AMP1 features the unique Marantz Musical Digital Filtering (MMDF), inspired by audiophile reference class technology. For Marantz, using standard digital filter solutions is not an option, as this filtering is crucial to the sound reproduction of digital input signals. As a result, the company invested extensively in gaining expert knowledge, leading into highly-acclaimed Marantz Music Mastering technology used in award-winning Premium Range 11 Series products. Adapted for the HD-AMP1 hardware design, the new solution is called Marantz Musical Digital Filtering. Two selectable, digital filter characteristics cater for different tastes, and each handles even the minutest of detail with loving care in the digital audio signal, transforming new media files into the finest of high-resolution playback.
Special Switching Amplifier Concept
The HD-AMP1 is the first ever Marantz Hi-Fi product that incorporated the concept of a switching amplifier. Up to now, switching (Class-D) amplifiers did show certain limitations which made them not acceptable for demanding Marantz sound engineers to be used in a premium Hi-Fi product. Now, the HD-AMP1 combines the unique Marantz HDAM technologies, the switching amplifier concept and an overall feedback loop, to guarantee a consistent performance with a wide range of loudspeaker types. Compared to regular switching amplifier concepts, the HD-AMP1 does not take the feedback signal at the output of the amplifier module, but right after the LC filter stage. In case the feedback is taken before the LC filter, the connected speaker is not taken into consideration in the amplification process, hence the amplifier reacts very sensitive to the connected speaker, and performance varies. With a carefully designed switching amplifier and the feedback taken after the LC filter the impact of a connected speaker becomes very small. In addition the damping factor defined by the output impedance of the amp and the impedance of the connected speaker is less sensitive to the frequency as well. The high slew rate of the amplifier concept and the high quality LC Filter itself ensure a wide bandwidth and flat frequency response. All adds up to an extraordinary Hi-Fi performance in a compact form factor.
The HD-AMP1 not only builds on the famous Marantz sound, it is also highly connectable. Optical and coaxial digital inputs as well as a USB-B port enable you to stream music directly from a PC or MAC, or connect other digital sources. iDevices can also be connected via the USB port on the front. For even more connectivity, Marantz also included two analogue inputs. The USB-B works in asynchronous mode to support not only 384kHz/32bits high-resolution audio but also the DSD 2.8MHz, 5.6MHz and even 11.2MHz formats for maximized performance and the most direct way to enjoy excellent quality. To safeguard quality when connected to a computer, Marantz built extended isolation around the USB-B input to eliminate the chance of high frequency noise generated by the computer entering the HD-AMP1.
High quality headphone output
For music lovers enjoying their favourite recording via headphone the HD-AMP1 features a high quality headphone stage with dedicated amplifier module HDAM-SA2. To work with a wider variety of headphones the gain factor can be changed from low to mid to high. By this it is possible to drive low to high impedance headphone without any problem.
Without doubt, the HD-AMP1 is a feast for the ears. But it also looks good. The solid aluminum front is supported by a double layer bottom plate and side panels with retro-style wooden look. Information on volume, input, resolution, and more is shown on the stylish Marantz Porthole Display, clearly resembling the company’s renowned design. This is pure craftsmanship.
Dual-layer chassis and aluminum die-cast insulator
The HD-AMP1 is housed in a dual-layer chassis featuring the addition of a bottom plate to the main chassis which suppresses any adverse effects of external vibration on sound quality. The feet of the chassis employ aluminum die-cast insulators to further absorb external vibration.
The Marantz HD-AMP1 offers a powerful yet sophisticated sound from modern and legacy sources in a beautiful small-format appeal. It accompanies the HD-DAC1 Headphone Amplifier with USB-DAC in the reborn Marantz MusicLink Series.
The latest addition to the new Marantz MusicLink series is the HD-CD1, a high-quality CD player in the same compact form as the HD-AMP1 amplifier, for which it is the perfect match. Combining more than 30 years of Marantz expertise in compact disc playback with the latest developments in digital audio technology, it’s ideal for use as a CD transport when used with the HD-AMP1, or as a CD player in any situation where a compact form-factor is required without any compromise on sound quality. Small it may be, but it makes use of state-of-the-art Marantz technology carried over from our Award-winning CD players, including a high-resolution 192kHz/24-bit digital-to-analogue converter from Cirrus Logic, a high-accuracy system clock, and the famous Marantz HDAM-SA2 amplifier modules, as found in our flagship Reference Series CD players and amplifiers. Selected components are also used throughout the audio signal path, for the very best reproduction of your music. A centralised CD mechanism, able to play MP3, WMA and AAC files as well as standard CDs, is also used for ultra-accurate disc-reading and, along with its analogue audio outputs, optical and coaxial digital connections are provided, allowing the HD-CD1 to be connected directly to the HD-AMP1’s ultra-high-quality digital-to-analogue conversion. The HD-CD1 also features the stylish MusicLink design, with a solid aluminium front panel, double-layer chassis for vibration isolation, and retro-style side panels, and also includes a high-quality integral headphone amplifier with adjustable gain to drive high-end headphones for personal listening and comes complete with a remote control for all its functions, also able to ‘drive’ a complete system of HD-CD1 and HD-AMP1. It’s a superb Marantz CD player – in miniature!
Marantz HDAM for superb audio performance
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.
