About the Marantz HD-AMP1

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.

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 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. 

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.

Customer Q&A

Crutchfield asked: Why did you buy this?
for my new marantz cd player [ Benediktas  Dec 24, 2018 ]
I choose the Marantz HD AMP1 because it had the exact set of features I was looking for and because of Marantz's reputation. I was looking for a small amp that I could use primarily as a headphone amp but could also power a pair of bookshelf speakers. It was a bit more than I wanted to spend, but there's a limited selection of amps with a good headphone amp that can also power speakers. I considered the Pro-ject MaiA and the McIntosh MHA150 as well. [ JON  Aug 07, 2018 ]
It is underrated and nice to look at, can not wait to see how it sounds. [ Davian  Apr 20, 2018 ]
Marantz reputation and product offering was most attractive to fit our need. [ GREAR  Oct 22, 2017 ]
This Pre-Amp is a bit expensive but the sound is really good, also able to play lostless music directly from an USB stick is a-plus. [ Ernest  Aug 10, 2017 ]
I chose this amp because I already bought the DefTech Studio Monitor 65 speakers from you and I will use this Marantz HD-AMP1 coupled to my pc for all my entertainment. I did a lot of research and these 2 items appear to be the best I can get in a small size with a big pure sound. [ Marc  Aug 03, 2017 ]
Very positive experiences with Marantz in the past. Chose this based on its reviews and its technical specs. [ ROGER  Jun 09, 2017 ]
Looks Classy. Good reviews. Compact size. Supports decoding of HQ audio file formats. Good experience with owning Marantz products. [ Krishnan  May 04, 2017 ]
Wanted it from Crutchfield because of your warranty and return policy. Buddy did a great job with me and, since you did not have brand new stock, showed me this one that should be just like new! Buddy did a great job. [ Clark  Jan 22, 2017 ]
Marantz for that modern era, what more could you ask for? [ Kevin  Aug 31, 2016 ]
It is the right size for the space I have and fit the specs also. It too had a good mention in Sound & Vision May issue. [ jeffrey  Jun 11, 2016 ]

7 questions already asked

How well would this amp pair with B&W 707 S2 bookshelf speakers? Is 35 watts per channel sufficient to drive these speakers to good effect? Setup would be in a relatively small room.
[ Mike  Feb 07, 2019 ]
6 answers
35 watts isn't even close to enough to get the best out of those 707S2 speakers..Yea, you will get sound, but you won't be close to reaching their potential. I would be pumping 100 watts of stereo power- not integrated into the speakers- the 700 series deserve that respect.
[ JAMES  Jun 13, 2019 ]
You should be happy with this amplifier. In my 15'x17' room, KEF 300 speakers powered by this amp are super loud.
[ Waterobert  Feb 12, 2019 ]
This is all speculation but it would probably pair pretty nicely. If you do a bit of digging, when the unit was first being paraded at shows, Marantz paired the unit with B&W CM1 v2's and also even larger floorstanding models.
[ Paul  Feb 08, 2019 ]
Hi Mike, I am also driving bookshelf speakers off the Marantz HD-Amp1. The sound is crystal clear and no need to crank up the volume. In my opinion, 35 watts per channel is more than enough. I love this amp and it is built like a rock. Marantz does a great job with the on-board DAC and with your speakers you will be fine. Just keep in mind that you have two channels so if you want to upgrade you might be better with another one. Hope this helps. All the best, Chris
[ Christopher  Feb 08, 2019 ]
The Marantz HD-AMP will sound great with your B&W 707 S2 in a small room. The amp is crystal clear when connected with an optical cable with wifi. The design and craftsmanship of the amp is beautiful. Since your speakers have a sensitivity of 84 db with extended highs they would not be good in a very large room with loud music. Your speakers will sound better with a small subwoofer in a small room with this amp since there are no bass & treble controls with this amp. The amp sounds great with a "you are there" sound in a large room with horn speakers like Klipsch.
[ JAMES  Feb 08, 2019 ]
Those speakers are low sensitivity. Using the rule of thumb that you get 3 dB every time you double power, your speakers would make roughly 100 dB. That is like the following: a Jet take-off (at 305 meters), use of outboard motor, power lawn mower, motorcycle, farm tractor, jackhammer, garbage truck. Boeing 707 or DC-8 aircraft at one nautical mile (6080 ft) before landing (106 dB); jet flyover at 1000 feet (103 dB); Bell J-2A helicopter at 100 ft (100 dB).
[ Ashton  Feb 08, 2019 ]
I'm a little wary about only 35 watts, how does it drive speakers? Do you have to crank it past half way? I currently own a Yamaha 100 wpc stereo receiver and worry ill lose volume.
[ ALAN R  Oct 27, 2017 ]
2 answers
honestly. unless you are using this in a very small room, i wouldn't mess with any amp that is less than 75 watts. it's not worth it. But also depends on your speakers as well.
[ JAMES  Jun 13, 2019 ]
Depends upon the efficiency of the speakers. This amp powers the KEF 300's I have very well since they are very efficient.
[ Woodsman  Oct 30, 2017 ]
as a class D amp, how will it handle low impedance loads like 4-ohm mini-magnepans?
[ John  Sep 06, 2017 ]

I have the Marantz hd-1 amp hooked up to a pair of Elac uni-fi b5 speakers(4 ohms). The amp has plenty of power and it sounds great. I listen at about 1/3 volume and it is loud.
[ James  Jul 10, 2018 ]
I own a pair of Sonus Faber Chameleon B bookshelf speakers, 4 ohm, 87 db and the Marantz HD Amp 1 drives them perfectly. This amp puts out 70 watts into 4 ohms.
[ Jeffrey  Mar 01, 2018 ]
This amp/dac is just amazing hooked up to my pc. My speakers are 8 ohms. It plays them with plenty of power. You will have twice the wattage going to 4 ohm speakers. I am sure you will love it. The dac is what makes it great sounding in my opinion. I play nothing but flac music recordings and there is no hiss or noise. Hi def movies sound great too.
[ Marc  Oct 24, 2017 ]
Mini Maggies!!! Those rock! I had some big Maggies and loved the sound! Of course I had a big a--- amp to drive them. For the mini mags, the 7050 will do an awesome job. The 50 watt rating seems conservative, and the THD is so low as to be undetectable. I say GO FOR IT!!!
[ THOMAS E  Sep 08, 2017 ]
When you enable "source direct" mode does it disable the subwoofer output?
[ Sealy  Jul 20, 2017 ]
1 answer
No, the Source Direct feature simply bypasses the amp's tonal control for more "pure" sound quality; but the subwoofer output remains active when Source Direct is used. For more details or to discuss further, please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. I hope that helps!

Can this unit be used as a multimedia device? PC Gaming, movies, music etc.
[ Brian  Feb 18, 2017 ]
2 answers
Hello Brian, I have my samsung smart tv hooked up to it via an optical input for better sound. i also use usb thumb drives to play wav files. the sound is terrific with my revel concerta2 speakers for both music and movies. However, I have not used it to play games or other devices. I would think that as long as your devices have an optical or coaxial output you should be able to get good sound from them providing you have decent speakers hooked up. The amp seems to have plenty of power and detailed, dynamic sound.
[ EILEEN D.  Feb 19, 2017 ]
No. This unit is designed for fine music reproduction only. It can accommodate both digital and analog sources.
[ Woodsman  Feb 19, 2017 ]
Does the AMP1 come with the same or better headphone amp as thr DAC1? Hard to find any information on this.
[ Ryan  Mar 17, 2016 ]
1 answer
I see that both the Marantz HD-AMP1 and HD-DAC1 employ Marantz's exclusive HDAM-SA2 technology and both have three gain settings available in order to provide optimum matching with the widest range of headphone impedances. So both headphone amps should perform very similarly, but there's no information to confirm that they are the exact same in each. I hope that helps. My Bio:
