This review is from: Marantz NA7004 Network Audio Player (Black) (Electronics)

Have had this for 3 days now and am very happy with it. The first thing I did after setting up was to download the firmware update. Sound quality is very good using the optical output - especially if you use lossless material like FLAC. Through the optical output I would say sound coloration character is "neutral". I have read reviews elsewhere that say sound quality was uneven while using the analog outs. My past experience with Marantz leads me to believe that break in of at least a hundred hours is necessary for those type of analog output stages to "flatten up. I tested the unit with 320 AAC files, 24 bit 96 khz FLAC, and WAV files and very good sound was obtained. Internet radio is the best sounding of any unit I have ever used. I am foremost a fan of vinyl but I can truly say this unit makes digital files "listenable". Much better sound then I expected . I hear no evidence of fatique at all.

I went ahead and purchased the 50 buck firmware upgrade to enable airplay functionality with Apple Ipod, Itunes, iPad products and tested it all tonight. Very satisfying. I connected an iPod to the unit and that also worked very well.In conclusion I feel the unit is worth the price and recommend it.

So what are the "cons'? One I can think of is that it is outrageous that Marantz does not provide the Airplay firmware upgrade free of charge to people buying the product today. The other things I dislike is that the unit will not decode 24 bit 192Khz FLAC files or Apple Lossless ones. You are however able to play Apple Lossless files stored in Itunes on your computer or iOS devices via Airplay and sound quality is excellent.

Is this unit for the rabid audiophile with a 100k system? Probably not. It produces great sound for a mid range system though and I feel a large portion of listeners will be very happy with it.

5.0 out of 5 stars Very Pleased - Fantastic Sound, April 15, 2011

I have had my eye on the NA7004 for quite some time. I purchased the NA7004 first and foremost to be used as a DAC (and second as a network audio player), and I am very pleased with it. The sounds is excellent...the DAC circuitry within the machine is from some of Marantz's much more expensive equipment which was limited edition and now sold out (KI Series). As another reviewer mentioned, break-in is important. I let it run with CD's on repeat and and amplifier off for 3 days straight.

I have been using it as an external DAC for a CD transport, as an external DAC for a digital music server, and I also have it connected to my network to play stored digital music files. I rip my own CD's in FLAC format. It also sounds great with lower bandwidth material - 320 Kbit and even 256 still sound quite good. FLAC is excellent, however. For me, this component has changed my audio system very significantly. It features an "M-Dax" circuit, which I don't use. The sound without M-Dax is great so why mess it up with processing? In all, sound is very much three-dimensional, super quiet, very dynamic, and overall tonally balanced. It sounds very natural and blows away any other digital sources I've had attached to my system.

The ability to play internet radio stations is a very pleasant surprise - there are some which broadcast in high bitrates and I am very impressed with the amount of content you can access and play back in very high quality with the NA7004. It is also great to be able to play Pandora through the NA7004. In all, this component is a terrific addition to my system and I sure wish I saw more good reviews for it.

There is a nifty iPhone app ("Wizz App") - a free download from iTunes - which serves as a remote control. You can also control it from a computer on your network by hitting its IP address. Very handy.

The only area in which I am disappointed is with its use as a media player with a UPNP Network Attached Storage (NAS) media server. The NA7004 seems to have a hard time "finding" the NAS on my network, and when it does, it is quite slow to switch tracks or search for different playlists. Since I mostly use the NA7004 as a DAC with a CD transport or with a hard disk based media server connected directly to the Marantz via coaxial digital cable, this is not a huge concern for me personally, but it could be a problem for others and I'd like to see it addressed with a firmware update (I am using the latest update as of this review). It could be my UPNP server is part of the problem - it is several years old and one based on newer technlogy may not challenge the NA7004 as much.

In all, I am very happy with this Marantz and I am glad I bought it!

4.0 out of 5 stars Use J-River Media Player Software instead of iTunes, March 22, 2011

This review is from: Marantz NA7004 Network Audio Player (Black) (Electronics)

There is a very good review of this product in the latest issue of Sound and Vision magazine. If you want FLAC then J River Media Player is available to accommodate you. I actually have the media player and it is excellent. Not only will it play FLAC but anything iTunes can throw at you as well.

If you need to rip your cd collection then there is an excellent program known as dbpoweramp. It is much faster than iTunes ripper and has a equally accurate error correcting program.

The absence of Wi-Fi could be overcome by extending your network using an access point and connecting your Marantz NA7004 via an ethernet cable. You get network connectivity and a stronger network signal as a bonus.

It has always perplexed me that Apple refuses to allow FLAC files in iTunes. Even more perplexing is that Apple fails to have have their own dvdmedia files (that play in their own dvd player software) to work with iTunes.

Apple could make a world of customers very happy if they would correct those omissions.
