Did you check out the dynamic Marantz HD-AMP1 Integrated Amplifier with USB-DAC on Ooberpad? This innovative, cutting-edge Marantz HD-AMP1 is a High-Class compact amplifier, with timeless, classic aesthetics. But don’t get swayed by its design, its breakthrough switching amplifier technology blasts out an earth-shattering 70W at 4ohms, while its dual crystal clock and discrete DAC post filter with Marantz. HDAM-SA2 modules make the standard counted sound feel as incredible as high-resolution audio. This new amp is also feature-packed with the unique Marantz Musical Digital Filtering (MMDF), with two selectable filter characteristics to meet demands for different tastes and music. Each handles even the finest nuance with extreme 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 maintain strict adherence to quality when connected to a computer, an extended isolationis built 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 elegant and appealing Marantz Porthole Display. While the solid aluminium front is supported by a double layer bottom plate and retro-style side panels. So are you excited to experience the compact ecstasy?

    Benefits of Marantz HD-AMP1 Integrated Amplifier with USB-DAC:

    Marantz MusicLink Series
    Marantz MusicLink Series

    Marantz again amplifies its dedication to an exemplary musical performance with the rebirth of MusicLink, a product series launched in 1990 with the emphasis on reproducing the music essentials from small-size, rarely-seen design components. The aim is clear: to bring the listener all the emotion and musical detail of the original sound studio, synergized with an appealing appearance and lush feel. It is not a coincidence that the creator of the delightful new MusicLink Series is once again Ken Ishiwata.

    A Combination of Stellar Marantz Audio Performance with Audiophile D/A Converter
    Unique Marantz Audio Performance with Audiophile D/A Converter

    Don’t underestimate the power of this little dynamo because of 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 enthralling 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 finest nuance with effortlessness.

    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 to globally-renowned 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 finest of detail with extreme 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 implemented the concept of a switching amplifier. Previously, switching (Class-D) amplifiers displayed 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 synergizes the amazing Marantz HDAM technologies, the switching amplifier concept and an overall feedback loop, to guarantee a consistent performance with a wide range of loudspeaker types. When drawn comparison 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 sensitively 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 class-leading LC Filter itself ensure a wide bandwidth and flat frequency response. All adds up to extraordinary Hi-Fi performance in a compact form factor.

    A Contemporary Level of Connectivity

    The HD-AMP1 not only builds on the highly-acclaimed Marantz sound, but 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.

    World Class Headphone Output

    For music lovers enjoying their favourite recording via headphone, the HD-AMP1 features a high-quality headphone stage with a 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, while eliminating the regular challenges.

    Elegant Timeless Look

    Without a 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 a retro-style wooden look. Information on volume, input, resolution, and more is shown on the stylish Marantz Porthole Display, sharing a strong resemblance with the company’s popular design. This is a representation of excellent 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 employs aluminum die-cast insulators to further absorb external vibration. The Marantz HD-AMP1 packs a punch with a functionally sophisticated sound from contemporary and legacy sources in an aesthetically appealing small-format appeal. It comes along with the HD-DAC1 Headphone Amplifier with USB-DAC in the reborn Marantz MusicLink Series
