About the Marantz HD-DAC1

Easy to listen to, tough to describe

When we first saw the drop-dead gorgeous Marantz HD-DAC1, we weren't sure exactly what to call it. A reference-quality headphone amp? A versatile digital-to-analog converter? A capable stereo preamp? Turns out it simply crushes all three categories.

Easy to listen to, tough to describe

When we first saw the drop-dead gorgeous Marantz HD-DAC1, we weren't sure exactly what to call it. A reference-quality headphone amp? A versatile digital-to-analog converter? A capable stereo preamp? Turns out it simply crushes all three categories.

As a high-end DAC, this Marantz converts your digital music into warm, detailed analog sound. As a high-performance headphone amplifier it combines power and finesse to help any headphone sound its best. Finally, as a stereo preamp with volume control and a wireless remote, the HD-DAC1 can bring your music sources and your favorite power amp or active speakers together to create a killer sound system. In the end, we're going to leave it up to you to decide what to call this impressive, all-around performer. 

High-res audio

A bona fide high-res all-star...

If you're into downloading high-resolution audio from websites like HDtracks, 2L, or Blue Coast Records, you'll love the HD-DAC1. Not only can it make your MP3 and CD-quality music sound fantastic, it also decodes high-res audio files up to 24-bit/192kHz resolution, so you can enjoy better-than-CD audio quality (free USB driver download required for Windows® PC playback). And this DAC supports both 2.8MHz and 5.6MHz DSD digital audio signals for bit-transparent playback of those high-res digital music files.

...that can make your headphones sing

The HD-DAC1's ultra-high quality dedicated headphone amplifier borrows powerful current feedback amplification technologies from Marantz's high-end Reference Series components for stunning headphone sound. And thanks to a selectable three-level gain control, it can drive virtually any headphones with ease — even high-impedance audiophile models up to 600 ohms.

Marantz HD-DAC1

Versatile connections

The HD-DAC1 provides the connections you need to make it the heart of your high-end music system. First, you get two USB ports: an asynchronous USB connection in back for plugging in your PC, plus a front-panel port for your iPod®/iPhone® or a USB thumb drive. Three digital audio inputs (1 coax, 2 optical) let you add a CD/DVD player, game console, or other devices with digital audio outputs. There's a minijack analog audio input for a smartphone or portable music player with analog output. You also get fixed RCA audio outputs for connecting to a receiver, integrated amp, or powered speakers, plus variable RCA outs when going straight into a power amp.

Customer Q&A

Can I connect my Samsung smart tv with hd-dac with optical cable so can I listen tv audio by headphones? If so, can I forward audio from tv to rca output to feed my amplifier?
[ Krzysztof  Dec 01, 2018 ]
1 answer
Yes. The HD-DAC1 does not support multi-channel soundtracks though so, you will need to set the audio output on your TV to 2 channel PCM (stereo). You can also connect the HD-DAC1's stereo RCA pre-amp outputs to your external amplifier.

Will this unit stay powered on continuously when not in use?
[ Bruce  Oct 21, 2018 ]
5 answers
When not in use you should turn off the power with the power on/off button on the lower far left front side of the amplifier. You will continue to get great sound as long as you leave it plugged into your computer.
[ WILLIAM J  Oct 21, 2018 ]
No. I am looking at mine now and power is off. I hope this helps.
[ John  Oct 21, 2018 ]
I guess. Ive had it on for over 4 hours and it didn't turn off. The top panel gets warm when continuously on. Checking the top heat can give indication. There is a standby mode and indicator on the front panel.
[ jacoub s.  Oct 21, 2018 ]
Yes, if you leave it turned on. Mine is on 24/7 attached to my music server.
[ Jerome  Oct 21, 2018 ]
Yes! It will remain powered on as long as it has power. If the power is switched it will turn on in its last state. Good luck!
[ Preston  Oct 21, 2018 ]
If I use this on my desk and connect my computer speakers to the fixed RCA output, can I switch between headphones and RCA at will, or will audio always come from both?
[ Kyle  Nov 15, 2017 ]
2 answers
You can select the output you want. It only sends a signal one direction at a time...
[ Tom  Nov 16, 2017 ]
The HD-DAC 1 is a Pre-amp, headphone amplifier component with no amplification capability for speakers - even small computer speakers. Marantz makes the HD-AMP 1 that does and it has both speaker and headphone outputs. It's traditional that when a headphone is plugged into the amp, the speakers are silenced. Both will not operate at the same time for obvious reasons. I own the HD-DAC 1 and use it with my AUDEZE LCD 3's. A great Combination for the money. Unfortunately, to realize the full potential of the LCD-3's, I will have to spend another $ 3,500.00. Hey, with some people it's golf clubs!
[ Steve  Nov 15, 2017 ]
Can this be used with a separate av controller such as the Marantz AV7703 ?
[ Joe  Sep 07, 2017 ]
1 answer
Yes, you could potentially use the HD-DAC1 with a separate AV7703 preamp/processor. To discuss in more detail please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. Thanks!
[ Larry  Sep 11, 2017 ]  Staff
Can you plug a USB Bluetooth receiver in to the front USB port to receive Bluetooth from a smartphone?
[ Patrick  Dec 21, 2016 ]
1 answer
The USB port is where i plug the phone in. I am not sure about using Bluetooth to make the connection, yet that does sound reasonable.
[ Deena  Dec 21, 2016 ]
Is the HD-DAC1 basically the same as the SA8005 with the "disk player" replaced by the headphone option?
[ Harry  Dec 25, 2015 ]
3 answers
Pretty much so yes, although to be sure the SA8005 certainly does have headphone output capability. Does look like the DAC itself is the same
[ mark  Dec 27, 2015 ]
Harry J. as I understand it. the basic difference is that the sa 8005 plays sacd discs, which as you know is another hi rez option. The sa 8005 has its own headphone option.
[ RICHARD T  Dec 26, 2015 ]
It appears they do play most of the same formats, I use my exclusively to play back high-res files from my Mac. So it does appear that they share many similarities.
[ JON  Dec 26, 2015 ]
Is the white one available? It looks better imo.
[ Wolfy  Apr 24, 2015 ]
1 answer
We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question.
[ Krissy  Apr 29, 2015 ]  Staff
Is Mac support better via USB or optical? I'm purchasing tracks from HDTracks.Com and would like to ensure all formats will work without fuss. I'm considering connection via optical only so drivers won't interfere. But I don't want to loose quality or ability to playback any format. I'm also worried about driver support 5 or 6 years down the road.
[ Fred  Mar 12, 2015 ]
2 answers
I don't have a Mac - just a PC I built. I am using the USB 2.0 driver (easy to download and setup), running USB from PC to Dac1 then to receiver. Sound is fantastic and headphone amp is also great. I have many 96 and 192 Khz files from HDTracks and other sources and they play great without a hiccup. With the option for DSD, it should be good for many years to come. If course, if you are an audiophile, something better will come along anyway.
[ John R.  Mar 13, 2015 ]
Both work well, I have an iMac and have used both. No drivers are required for USB as long as you are running a reasonably current version of OS X.
[ Peter  Mar 13, 2015 ]
