Marantz HD-AMP1 Digital Integrated Amplifier Announced

Marantz HD-AMP1 Integrated Amplifier

Marantz announced the HD-AMP1, an elegant compact digital integrated amplifier with USB-DAC engineered to the highest Marantz purist audiophile standards. Building on the success of last year’s HD-DAC1 Headphone Amplifier, the HD-AMP1 was created to serve at the center of a music system. This ultra-high quality amp delivers 2 x 70W from a special switching amplifier circuit, providing amazing sound from all sources including the highest of high resolution audio files.

Housed in an elegant compact chassis that occupies just over 1 square foot of desktop or shelf space, the HD-AMP1 is equipped with multiple digital inputs, including 2 optical, 1 coaxial along with 2 USB ports. It features the ability to decode the latest generation lossless high-resolution audio file types, including WAV, AIFF, ALAC, FLAC at up to 24-bit/192-kHz resolution, along with the ability to play MP3, WMA and AAC tracks. The rear panel USB-B port features advanced noise isolation so users can connect a PC or Mac and stream even higher resolution files, up to 32-bit/384-kHz. The HD-AMP1 is equipped with the reference grade ESS SABRE DAC and dual master clock crystals for the widest bandwidth, highest dynamic range and lowest distortion, and the HD-AMP1 can also play DSD hi-res audio tracks including 2.6/5.2/11.2-MHz.

The HD-AMP1 delivers 2 x 70 W into 4 Ohms; clearly handling even demanding music parts thanks to an ultra-stable power supply and Marantz exclusive Current Feedback technology. The Dual Crystal Clock and a discrete DAC post filter combined with the company’s highly-acclaimed HDAM pre-amplifier modules make standard counted sound feel like high-resolution audio. A high-current audiophile SABRE D/A-Converter with 384kHz/32bit processing capability is able to reproduce even the smallest details with ease.

The HD-AMP1 is the first ever Marantz Hi-Fi product that incorporated the concept of Class-D amplification. Up to now, switching (Class-D) amplifiers had certain limitations which made them unacceptable for demanding Marantz sound engineers to be used in premium Hi-Fi products. Now, the HD-AMP1 combines the unique Marantz HDAM technologies, the Class-D amplifier concept and an overall feedback loop to guarantee a consistent performance with a wide range of loudspeaker types.

The HD-AMP1 is also highly connectable. Featuring two USB ports, one on the front and one on the back, the HD-AMP1 lets users connect their favorite iDevice or USB drive to the front panel USB port, and a PC or Mac to the rear panel USB-B port to stream high resolution audio tracks. In addition it features advanced noise isolation to guard against digital noise from degrading the high-resolution sound. For even more connectivity, Marantz also included two analog 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.

The compact, elegant chassis features a premium brushed alloy front panel with matching knobs along with our signature Porthole round front panel 2-line OLED display, which features 3 dimming, levels and off. The stylish woodtone side panels add a luxurious touch and the robust chassis features our rugged dual bottom plate construction for maximum rigidity coupled to aluminum alloy chassis feet for maximum vibration resistance.

The Marantz HD-AMP1 Integrated Amplifier with DAC-mode is expected to be available in January 2016 for $1,099.
