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 Marantz Musical Digital Filtering

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. To round up, 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.

Modern connectivity

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.

Elegant look

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.

The Marantz HD-AMP1 offers a powerful yet sophisticated sound from modern and legacy sources in a beautiful small-format appeal. Accompanying the HD-DAC1 Headphone Amplifier with USB-DAC in the reborn Marantz MusicLink Series, it will be available in black and silvergold from January onwards.
