Famous Marantz sound in a space-saving package
Folks around here at Crutchfield really go for the warm, detailed sound of Marantz amps, and so do our customers — just check out all the glowing reviews. But a full-size Marantz amp may not always be right for every room. If your system is going in a bedroom, den, dorm room, or home office something a bit smaller like the Marantz HD-AMP1 could sure come in handy. This compact integrated amp delivers the powerful, dynamic punch that Marantz amps are famous for, but in a more space-saving size.
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 , 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 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.
A Marantz first
Once it sinks its teeth into your music, the HD-AMP1 knows just how to deliver warm, dynamic sound to your speakers. The conservative 35-watt stereo power rating only tells part of this amp's story. Power is generated by a wide-bandwidth, audiophile Class D amplifier — a first-ever for a Marantz component amplifier — and voiced by Ken Ishiwata, Marantz's renowned design guru. This efficient, cool-running design allows the amp to handle the heavy demands of 4-ohm speakers as well as dynamic peaks in music without breaking a sweat. The output stage utilizes current feedback circuitry — first developed by Marantz — to ensure clean playback with minimal distortion while driving both easy and difficult loads. So when that muted trumpet solo is suddenly augmented with the full power of the entire horn section, the HD-AMP1 can handle that sudden jolt of brass cleanly in all its dynamic glory.
