The NAD C 658 is a new type of stereo component that opens up completely new possibilities for audio playback. The preamplifier, with its two optical and coaxial digital and analog high-level inputs, is not only ideally equipped for playing all classic music sources, but also for all modern and future media: The integrated Bluetooth module not only receives music streams from smartphones or tablets in the highest aptX HD quality, but also sends them on to another Bluetooth receiver, e.g. wireless headphones. The C 658 connects to the home LAN or WLAN network as well as online streaming services or Internet radio stations and other BluOS players or music servers registered in the network via BluOS.

But that's not all: There are two MDC slots on the back of the preamplifier for accommodating modules for connecting HDMI A/V sources or future technologies. And to ensure that the stereo system always sounds optimal, the integrated Dirac Live room correction precisely adjusts the sound parameters of the C 658 to the acoustics of the listening room.
