Redefining the Architecture of Hi-Fi Playback

BluOS™ Enabled

Onboard is BluOS, the most sophisticated High Res streaming system available. BluOS natively supports over 15 streaming music services and indexing of over 250,000 tracks from local network sources. The C 658 becomes a node in the BluOS ecosystem, allowing high res network streaming to 64 zones and control options for iOS, Android, Windows, and Mac OS phones, tablets, and desktop devices. BluOS also supports all major smart home controllers and is available in a wide range of products, making it easy to create a whole house audio system with the C 658 at its heart.

Traditional NAD Performance and Value

The C 658 is part of the Classic Series of components, which have an enviable reputation for giving music lovers more enjoyment for less money. If a solid block of hand-crafted aluminum with gold-plated accents is desired, other options might be more suitable. For state-of-the-art performance and features in a sturdy no-nonsense package, the C 658 is ideal.

High Resolution in Every Detail

Most NAD components have been High Res for 45 years, boasting very wide bandwidth, low distortion, and ultra-low noise. With High Res digital recording and streaming, combined with advanced technology like MQA, record companies are opening their vaults and releasing Studio Master Quality recordings. MQA decoding is available through BluOS streaming content. The C 658 is pure High Res from input to output and features the ESS Sabre 32bit DAC, one of the best performing DACs on the market today, with its 118dB Dynamic Range and incredibly low jitter spec. All preamp functions are executed in the digital domain, including the same wide range non-truncating digital volume control used in the Masters Series components. This offers an incredibly short analog signal path that, rather uniquely, is identical for all volume settings. Sophisticated active power supplies provide super clean voltages to all circuits to keep noise and distortion at the edge of measurability.

Make the Speakers Disappear (It’s Not Magic)

The C 658 is the first NAD stereo component to feature Dirac Live room correction*, the most sophisticated and effective room correction available. Dirac corrects the impulse response of speakers, in addition to the frequency response of the room, for a truly transparent window into the musical performance. When room resonances are tamed and transient response is corrected, the result is magical. Speakers have never sounded this invisible or this good
