The new Marantz HD-AMP1 is a high class amplifier compact in size, which has a classic and elegant look. But do not let this draws you in deception, its advanced switching amplification technologies can have a remarkable power of 70W into 4 Ohms, while its clock with dual oscillator and the discrete DAC with filter modules Marantz HDAM-SA2 allow the standard sound may be heard in an incredible way as if it were high-resolution audio. This new amplifier is also equipped with Marantz Musical Digital Filtering (Digital Filter Marantz) Musical with two filter characteristics can be selected to suit different tastes and types of music. Each of them also runs the minimum digital audio details with great care. Since the new media of today are available not only in the resolution 44.1 kHz / 16 bits, similar to the CD format, Marantz developed the digital section to handle the signals at resolutions up to 384kHz / 32bit and DSD 2.8MHz / 5.6MHz / 11.2MHz. Optical and coaxial digital inputs are ready to be connected to a TV or set top box and there is a USB-B port to stream music directly from your PC or MAC. IDevices can be connected via the USB port on the front panel. To safeguard the sound quality when connected to a computer, we have built an extensive isolation circuit around the USB-B input to eliminate the possibility of high-frequency noise generated by the computer connected to the HD-AMP1. The information concerning the input volume, resolution, and other parameters are displayed on elegant display Marantz porthole. Furthermore, the solid aluminum front panel is supported by a bottom plate in the double layer and by the side panels in retro style.
Marantz MusicLink series
Marantz still increases its dedication to musical performance with the rebirth of MusicLink, a series of products launched in 1990 were dedicated to the reproduction of the essential elements of music with small products and original design. The goal is simple: give the listener all the excitement and detail of the original music recording studio, combined with an elegant look and a feeling of prestige. It is no coincidence that the creator of this delicious new MusicLink series is once again Ken Ishiwata.
Marantz unique audio performance D / A converter audiophile
Do not be fooled by its compact size. HD-AMP1 offers a powerful 2x 70W into 4 ohms which is fully able to handle even the most demanding musical parts thanks to an ultra-stable power supply and the current feedback technology Marantz proprietary. The double oscillator clock and a discrete DAC followed by a filter made with preamp Marantz HDAM-SA2 modules allow the standard sound may be heard in an incredible way as if it were high-resolution audio.
A D / A converter SABRE high current and audiophile-quality, with processing at 384 kHz / 32-bit, is able to very easily reproduce even the smallest details.
Marantz Musical Digital Filtering
HD-AMP1 has the unique filtering technology Marantz Musical Digital Filtering (MMDF), inspired by the class reference technology for audiophiles. Marantz using standard digital filtering solutions is not an option, since this filtering is essential for the reproduction of the sound of the digital input signals. As a result, the company has invested heavily to acquire specific knowledge, which led to the development of the renowned Marantz Music Mastering technology, which is used in the award-winning range of premium products in the Series 11. Adapted for the hardware configuration of HD-AMP1, the new solution is called Digital Filtering Marantz Musical. Two digital filters with selectable characteristics suited to meet different tastes. Both also run fine detail with loving care for the digital audio signal, transforming the new media in the best high-resolution playback.
Switching amplifier particular type
HD-AMP1 is the first Hi-Fi Marantz never realized that integrated a switching amplifier. Until now, the switching amplifiers (Class D) showed some limitations that did not allow them to be accepted by the most demanding engineers of the Marantz sound, to be used in a high-level Hi-Fi product. Now, HD-AMP1 combines the unique technologies Marantz HDAM, a switching amplifier and a general feedback circuit to ensure consistent performance with a wide range of speaker models. Compared to ordinary switching amplifier concepts, HD-AMP1 does not take the feedback signal at the output of amplifier module, but immediately after the LC filter stage. If the feedback is taken before the LC filter, the speaker connected is not taken into account in the process of amplification, so the amp reacts very critically depending on the connected diffuser and performance may vary. With a carefully designed switching amplifier and the feedback taken after the LC filter, the impact of the speaker connected to the performance becomes very low. Furthermore, the damping factor defined by the impedance of the amplifier and the impedance of the connected loudspeaker is also less sensitive to frequency. The high speed of response of the amplifier concept and the high quality LC filter ensure a wide bandwidth and a linear frequency response. All this is to have an extraordinary Hi-Fi audio performance in a small size of the product.
HD-AMP1 not only has the famous Marantz quality of sound, but also of a great connectivity. The coaxial and optical digital inputs and a USB-B port provides 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 panel. For enhanced connectivity, Marantz has included also two analog inputs. The USB-B port is operating in asynchronous mode to support the high-resolution signals 384kHz / 32bit and even DSD formats to 2.8MHz, 5.6MHz and 11.2MHz to maximize performance and to enjoy great sound quality. To safeguard the quality of sound when connected to a computer, Marantz has built an extensive isolation circuit around to the USB-B to eliminate the possibility of high-frequency noise generated by the computer connected to the HD-AMP1.
High-quality headphone output
For music lovers who want to listen to their favorite recordings through headphones, HD-AMP1 has a stage for high-quality headset with a dedicated amplifier module HDAM-SA2. To be able to work with a wider variety of headphones the gain level can be changed to low, medium and high. In this way it is possible to drive without any problem headphones at low and high impedance.
No HD-AMP1 doubt is a joy to the ears. But it is also good to see. The solid aluminum front panel is supported by a double-layer bottom plate and side panels wooden type, in retro style. The information concerning the input volume, resolution, and other parameters are displayed on elegant display Marantz porthole, which clearly recalls the renowned design company.
Frame double layer chassis with aluminum die-cast insulators
HD-AMP1 is housed in a double-layer chassis with the addition of a bottom plate to the main frame that eliminates the potential negative effects of external vibrations on the sound quality. The aluminum feet of the frame employing cast insulators to further absorb the external vibration.
Marantz HD-AMP1 offers a powerful and sophisticated sound to the modern and traditional sources in a beautiful object of small size. He joins amplifier for HD-DAC1 USB headset with DAC in the renewed Marantz MusicLink Series.
