This ultra-high quality dedicated Headphone Amplifier creates simply amazing sound because it uses Current Feedback amplification technologies from Marantz’s high-end Premium 11 Series. Headphones have always added extra intensity to music, now with the Marantz HD-DAC1 that intensity reaches new climactic heights. This completely new product category comes with a new design, but as always with the unmistakable Marantz family resemblance.
The powerful HD-DAC1 can drive audiophile high-impedance headphones up to 600 ohm - with complete MODE ease. All thanks to its three-level gain control, Marantz HDAM-SA2 modules, a high current audiophile DAC (CS4398), and its Premium Quality fixed and variable RCA outputs. It is so powerful it not only drives headphones, you can also directly connect it to your Hi-Fi integrated amplifier or to a pair of active speakers or power amps. It’s also highly connectable.
Optical and coaxial digital inputs as well as a USB-B port enable you to stream music directly from your PC or MAC; iDevices can also be connected via the USB port on the front. For even more connectivity we have also included an analog input. The USB-B works in asynchronous mode to support not only 192 kHz / 24bits high-resolution audio but also the DSD 2.8MHz and 5.6MHz for maximized performance and the most direct way to enjoy excellent quality. To safeguard quality when connected to a computer, we built extended isolation around the USB-B input to eliminate the chance of a high frequency noise being generated by the computer when entering the HD-DAC1. We even included a jitter remover and Dual Clock for extreme accuracy. Info on volume, input, resolution, etc. is shown on the stylish Marantz Porthole Display. The solid aluminum front is supported by a double layer bottom plate and retro-style side panels. Pure craftsmanship.
