Andre Marc has posted a review of the Marantz HD-AMP1 integrated amplifier and DSD DAC ($1099) at Audio Video Revolution. His conclusions:
“The Marantz HD-AMP1 is a great addition to the Marantz line. The sonics were absolutely beyond reproach at this price point (and well beyond). The feature set is remarkable, and the built quality is exceptional…The Marantz HD-AMP1, at $1099, is going to be my go to recommendation for folks looking for an audiophile grade amplifier, DAC, and file player. I can think of no other product that currently competes with it directly. The HD-AMP1 is a no risk purchase in my book.”
