A versatile high-res champ

Just because it's small, don't think the HD-AMP1 is short on features. With its built-in, high-resolution digital-to-analog converter and array of both digital and analog inputs, this amp is ready to play from a wide variety of sources such as network music streamers, disc players, a TV, or a computer. Plus, a convenient front-panel USB port makes it easy to plug in an iPod®, iPhone®, or a thumb drive loaded with music.


Connect your computer via the HD-AMP1's rear-panel USB input and enjoy your entire library of digital tunes through your favorite speakers. If you're into downloading high-resolution audio from websites like HDtracks, 2L, or Blue Coast Records, you'll love this amp. Not only can it make your MP3 and CD-quality music sound fantastic, but it also decodes high-res audio files up to 32-bit/384kHz resolution, so you can enjoy better-than-CD audio quality. (Free USB driver download required for Windows® PC playback.) And this Marantz supports 2.8MHz, 5.6MHz, and 11.2MHz DSD digital audio signals for bit-transparent playback of those high-res digital music files.
