NAD C 658 BluOS Streaming DAC

$1,999.00

Out Of Stock

The NAD C 658 is a new kind of stereo component, one that at once changes preconceptions and opens new possibilities for audio reproduction. You see, there has never before been a component offering such a rich palette of both new and proven technology. As we move deeper into the 21st Century the way music is distributed and enjoyed continues to evolve away from physical media to streaming. It also has moved away from analogue to digital. The C 658 has incorporated these fundamental truths to create an entirely new type of component that combines a network streamer, a state-of-the art DAC, and many aspects of the traditional preamplifier into a single highly cost effective package. And thanks to NAD’s exclusive Modular Design Construction, it will keep pace with the latest technology, not yet introduced, but inevitably coming in the future.
