Question: Does na7004 grom usa support spotify when used in Europe ?Does it have global quarantee or just US one?Best regards,Maciek Mocek
Document: Only support Spotify through Airplay;  I also purchase the receiver SR5007 and it has Spotify built-in;  A major disappointment! The software/firmware updates happened frequently, hopefully they will update with Spotify...
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 .
The sound is so smooth, clean and open. I wished I can sit there and listen for many hours. The internal dac beats the dac from the HK635 and Sony 5ES receivers.The headphone amp gets me hooked when I tested with my AudioTechnica ATH-900X. I would get another just for the headphone I could afford one. For now I can live with Fiio E17I'd like to knock 1/2 star for these reasons:- It doesn't support playlist, especially when playing from usb flash drive.
I can play music from any PC with itune installed or WMP, from my iphone/ipad. So the NA7004 does support the AirPlay and included in the latest firmware.
The unit would not stay on when the on button was used. The button would flash and the unit would immediately shut down. Had to return it. Was really disappointed. Amazon was great with the return.
The NA7004 delivers remarkable sound quality from internet radio, streaming and iPhones. I already had a good experience with the unit in Europe. My only disappointment with the American  version is the lack of an FM tuner and digital radio.
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.
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!
I guess one can't believe everything he reads, eh?---Marantz, you're almost there. Address this serious issue and put a little more effort into the network control applet. You'll have a brilliant device worthy of 5 stars.
This new piece from Marantz looks very nice and could be a serious competitor for Peachtree audio, but I'm not sure if I even want to order one if I'll have to box it up and return it right away. Here's why:  According to the specs, the unit supports WMA, MP3, MPEG4, AAC, WAV, and FLAC. What's missing here Marantz,Inc.??
Answer: I have used several decades Marantz and had never a broken unit, I'm sure that Marantz Europe will help you with service if needed.Be aware that US equipment is build for 110Volt 60Hz, Europe has 230Volt 50HzBest Regards,Andries Bosma
