The NA7004 is your ideal connection to your favourite music, no matter where it comes from – whether it’s from
your PC, external hard disc, or as an FM, DAB or DAB+ radio station broadcast in your country, or even on the other side of the world via Internet radio or music service Napster. The NA7004 connects to them all. That’s because it incorporates technology based on the DLNA1.5 standard for audio streaming. This functionality can also be found in other products, but here it is much more directed to music lovers and audiophiles, because Marantz has done everything to ensure top-quality audio: rigid cabinet structure, strong power supply, audio output stage applying the famous HDAM-SA2, and fine-tuning by customized components. This network audio player is even ideal for people with no network installed in the home. Simply hook-up the NA7004 via USB connector on the back to your PC and it will recognize the NA7004 as an external sound card. That’s the most direct way to enjoy excellent quality. And there’s more: digital inputs, iPod-digital-compatible USB and optional Bluetooth reception. This is versatility in the extreme, but amazingly it’s also extremely easy to operate via the large display. It all goes to make the NA7004 your open door to a myriad of music stations, podcasts, documentary channels and more – all with the best possible audio quality.
