Throughout the HD-AMP1, there are three circuit blocks that feature Marantz's exclusive HDAM-SA2 technologies—including the analog front end and D/A converter I/V block, as well as the dedicated headphone amplifier block, which has its own volume control and features three selectable gain levels to handle the widest range of headphone impedances. In addition to the digital inputs, there are two analog inputs and a subwoofer output.
