Marantz NA7004

The Marantz NA7004 is a network audio player that streams audio from a variety of digital sources to standard S/PDIF outputs. The built-in vTuner enables connections to online services such as Rhapsody, Napster and Pandora through a simplified interface for streaming audio.

Digital media can also be connected through a USB input from an iPod, iPhone, USB memory stick or external hard drive. The DLNA 1.5 standard is observed to allow wireless connections to media servers, and the system is fully Windows 7 compliant. The creation of analog signals is run through HDAM SA2 analog circuits, and an impedance-matching copper plate shields the analog outputs from interference from the rest of the system. The digital outputs are also shielded to prevent bleed-over into other systems. For headphone listening a separate high-speed current buffer circuit is used that creates a clear, distortion-free signal.
