Hi-fi manufacturer Marantz has experimented with home media streaming for several years, but until now it has been mostly proprietary. The NA7004 Network Audio Player is perhaps the company's first attempt at creating an open digital entertainment hub, which not only incorporates DLNA and AirPlay media streaming but DAB+ radio and a DAC.


The NA7004 maintains the look Marantz debuted in 2009 with its '003 range of components. The rounded edges feature a resin construction, while the front of the unit is brushed aluminium. The unit features a blue, three-line OLED display that is visible from across a room, which is handy because the unit doesn't feature any sort of on-screen display (OSD) for your television.

The display is surrounded by a smattering of handy controls including Play/Pause and so on, as well as a Menu and direction pad. At the bottom of the unit you also get a headphone output and corresponding volume control.

The remote control is well laid out and features direct selection of all inputs. If you have a Marantz receiver it will also provide limited control of that too.


If you're looking for a music player that will spin anything short of a physical disc, then the NA7004 is essentially a one-stop shop. It offers internet radio with thousands of stations at your fingertips, digital radio in the form of DAB+ (for the city slickers), in addition to AM/FM, a high-quality DAC with USB, direct iPod/MP3 player connection, DLNA media streaming from computers and compatible devices, and Apple's AirPlay standard. Just be aware that registering for AirPlay costs an additional US$50.

The Marantz features support for a number of different audio formats including MP3, WMA, AAC and FLAC up to 24-bit/96MHz. While the player will relay the sound of video content via AirPlay, the player doesn't support picture or video files.

Marantz offers its M-DAX system on the NA7004, which is designed to "put back what compression takes out", but most people will find this needless. The switch simply adds extra treble to the mix and given the likely quality of the target market's audio files it's redundant.

As the unit can be used as a stand-alone DAC, you'd expect it to feature some cutting-edge digital processing, and, according to Marantz, it does. The player uses the Cirrus CS4398 chipset, which may not be the household names that the Burr-Browns and the Wolfsons are in the audiophile community, but Marantz also uses the DAC in its AU$2500 flagship CD player.

The system offers a number of inputs and outputs befitting a high-end digital player. For inputs you get USB, digital coaxial and optical, antenna and, of course, Ethernet. On the output side, the Marantz features both optical and coaxial (just in case, say, you own an even higher quality DAC) and stereo outputs. The only thing we miss is the lack of any video output and feel this limits a user's ability to navigate through long lists of content.

While the system also supports Last.FM and Napster, unfortunately these won't (currently) work in Australia.


In the bad old days of networked music players, getting them to work was always a little bit science, a little bit voodoo. But Marantz's latest player was quite easy to set up — simply hook in an Ethernet (no wireless, unfortunately) and the network set-up wizard does the rest.

The NA7004 found the content our DLNA-compliant NAS served up without a problem and we were able to play our music with the benefit of the Marantz's high-quality DAC. As we mentioned, the NA7004 has no OSD and the only issue we had at this early stage was that navigating through long lists was quite slow despite a small amount of acceleration. The ability to choose the first letter of the artist or song would help greatly here.

Instead, we found it much easier to use our iPhone via AirPlay or DLNA-compatible Windows PC to choose from our collection and serve it straight to the player. But no matter which way the digital music went into the sausage machine, the resulting meat parcels were certainly delicious. Even with low-quality files the player was able to dig up plenty of detail and bass weight, and was indeed the equal of the wireless Arcam rDAC we were using as a comparison. In addition, we found little difference between listening to a file through AirPlay and one delivered from the network server through the on-board media browser. Unlike a system based on Bluetooth, such as the aptX system used on the Creative D200, the file is seemingly delivered without being compressed. Having used AirPlay on several playback devices, we can now say that this is one of the best ways to deliver wireless music from your Apple device. While Marantz still offers the AU$499 IS301 wireless iPod dock, the addition of AirPlay to its devices supersedes it. No longer do you need a fussy iPod adapter, which can get lost behind the couch, as it's just a wireless network.

One interesting caveat is while the Media Player supports most file types it won't serve up Apple Lossless files, but of course you can still play them through the AirPlay service.

Comparisons between the on-board DAC and a dedicated sound card, such as the Creative X-Fi Titanium HD, were also positive. If you don't feel confident rooting around in the innards of your desktop computer this is an even better way to deliver high-quality audio from your PC.

Next we connected an Oppo BDP-83 to the NA7004 in order to decode a copy of Nick Cave's "Red Right Hand". The Marantz was able to capture the track's intimate, yet malevolent atmosphere and didn't let the bass become woolly and out of hand. When compared to the Arcam rDAC and the Cambridge Audio DacMagic, we were impressed by how well the Marantz performed against the two highly regarded DACs. If you have an old CD player with a digital out, the NA7004 could become the new centrepiece of your system.

While digital radio has been with us around 18 months, there are still very few "hi-fi" components available that receive it. We were quite taken by the optional UP-DT1 DAB+ tuner (AU$399) for Onkyo receivers and believe it's the best-sounding unit we've heard. So if you were to add a high-quality DAC to this, does it mean the Marantz is a sure-fire winner? Unfortunately, no. Like the Cambridge Audio Azur 650T DAB+ the Marantz digs up a little too much of the digital hash on low bitrate broadcasts. Yet, it's still listenable, and the unit's bright OLED screen and general usability makes the experience enjoyable.


Devices such as the NA7004 are designed to appeal to the "digiphile" who wants to do away with flimsy, expensive physical media and explore the wealth of content at their fingertips. While you can hook this unit up to a home theatre system, it would probably be better suited to a stereo set-up where the lack of an OSD isn't an issue.

While AU$1500 may seem like a lot, if you tally up all the cost of a separate DAC, DAB+ tuner and media streamer the Marantz NA7004 begins to make more sense. Great sound, the convenience of a single box, plus the addition of AirPlay makes this one of the best stereo components we've come across in a while. If you've resisted laying Ethernet cable around your house this is one of the best reasons to reconsider.

"Lot of Hype, Bitter Disappointment"

The Good:Fabulous Sound

The Bad:User interface, connectivity, iphone app, service support

I regularly read reviews of electronics products, from as many sources as posisble, and sometimes rely on them to guide my purchases. But it never ceases to amaze me how effusive and complimentary most reviews are about big name brand products. So is the case with Marantz NA7004. I read the reviews for this player before buying it. I would have bought it anyway, even if reviewers had given it 3 stars. I am a long standing Marantz user, and it was logical for me to buy the network player _ chosing it over Sonos _ when the time came for moving my CDs to digital medium.

But I wish the reviewers, including ZDNET, CNet,Hometheaterreview, hifireview and others, had been more honest and incisive instead of regurgitating what appears to be company handouts. I don't need the review to tell me about the fabulous specifications -- they are all available in the online manual. What I didn't know I found out after purchasing it, and I was sorely disappointed. But most of my disappointment must be directed at Marantz for shortchanging its loyal customers and fans. I still think they are the best sound engineers in that price range. But when it comes to networking and UI, it's another story. So here are some serious issues I have with the NA7004:

1. The ipod remote control app Wizz is one of the worst apps ever made. It is shamefully inadequate, slow to operate, unreliable and exasperatingly difficult to manage. It does not control volume, does not allow the creation of a playlist as you go while listening to music (which Sonos does), provides very little information on the screen, does not allow to jump between music servers without going postal, and is generally a wretched piece of software ever written.

2. I use the NA7004 as a DAC as well, connecting my old Marantz CD player to it. The point is to enjoy the NA7004's superior DAC while playing CDs. So far so good. But try playing MP3 CDs. Doesn't work. The NA7004 doesn't recognize MP3 digital signals! How weird is that? It can play MP3 from a USB thumb drive but not from a CD?

3. The front USB port cannot handle a big sized external hard disk. I tried connecting my western digital 3TB HDD but to no avail. The NA7004 shows "Loading files" on its screen for ages without actually completing the process. I tried a 500 GB hard drive. Again no result. In fact hooking up hard drives to the player freezes all other functions. Even the Music Server and Internet Radio refused to work while the hard drive was plugged in.

4. The rear USB port is only meant to connect laptop computers. It doesn't take external hard drive. How silly is that? Who would want to sit down a laptop on a music rack!

5. So I call Marantz service support in the U.S. The technician who answers the phone has no answers to my problem. He says he will "escalate" the matter and let his superiors know. When I mention the iphone app, he treats me like I am an idiot. His words: "We NEVER had any complaint from our customers about the app. In fact they LOVE it." Yeah right!

Other than that, it is a great system. Only, it's US$450 more expensive than a Sonos, which does all these things and more. I borrowed a friend's Sonos and heard it over several days. Its DAC is darn good. The sound staging is superb and so is the bass. And its iphone app? It's to die for! An absolute joy to operate. Easy, intuitive and everything you can ask for. If you are not an ardent, fanatic audiophile you won't notice the difference in the sound between a Sonos and Marantz. If you are not a Marantz loyalist like me you should save that $450 and buy a Sonos. I would be willing to overlook all these shortcomings if at least its iphone app was presentable. To me, the Wizz is a total deal breaker. Come on Marantz! Get it right. Develop a better app. We are even willing to pay to buy it!!!

How's that for a honest review without going ga-ga as most "professional" reviewers tend to? One wonders what is in it for them?

for $1499 buy a sonos bundle for 2 rooms. Even better 3 logitech squeeze box's i don't see the point. once again Australia ripped off when it comes to tech

This article list the Australian Price as $1499 but the Marantz USA site lists this product at $799. Why such a big difference?

Regarding the device not having wi-fi I suspect this is a good thing. Wi-fi standards evolve all the time whereas the DAC and DAB+ in this device should last you a long time. Simply buy an Apple Airport Express and connect a usb, optical or ethernet cable from it to the Marantz. Presto, the whole thing is wireless and you can buy a new Airport Express when whatever new standard (i.e. above the N-standard) comes out.
