Extremely versatile and generous in its features, the NAD C658 is an integrated solution, which is at the same time an audio network player, a high-resolution audiophile DAC and a stereo and phono preamplifier. It is compatible with the BluOS application developed by BlueSound, allowing remote control of the player as well as multi-room integration. Complete, it offers an extensive connectivity, balanced and single-ended, allowing it to be associated with the vast majority of audio systems, but also a wireless and network connectivity with Ethernet RJ45 Gigabit, WiFi and Bluetooth 5.0 bidirectional. It even has a phono (MM) input and two subwoofer outputs for adding subwoofers. Scalable, the C658 also has two slots for additional MDC modules (not included).

Performance is the key

The NAD C658's chassis conceals an optimized architecture based on high-end audio components selected to deliver the richest and most accurate sound reproduction possible. It features a 32bit ESS Sabre digital-to-analog conversion chip that offers excellent performance, with a wide dynamic range and low jitter. All the functions of the preamplifier are performed digitally, including the volume control, identical to the one present in the Masters range of the brand. This makes it possible to maintain a short analog circuit, identical for all volume controls. The power supply stage is also optimized to provide a clean electrical signal to all the circuits and thus keep noise and distortion at a very low level.

Balanced, single-ended and subwoofer outputs

Equally well suited for operation in a single-ended or balanced integration, the C658 features both an unbalanced RCA and a balanced XLR output with pre-amplification. It also offers a stereo subwoofer output, allowing the connection of one or two subwoofers, for deeper bass. Finally, the front panel of the C658 provides a 6.35mm headphone output.

WiFi & Bluetooth

Of course, the NAD C658 is not to be outdone in terms of network connectivity. It features a dual-band WiFi controller and a two-way Bluetooth chip that supports the high-resolution aptX HD wireless codec. This makes controlling your music playback remotely a breeze.

BluOS & Total compatibility

The BluOS system, on which the NAD C658 is based, is a real boon for music lovers looking for a versatile device and streaming lovers. With its extensive compatibility, it will allow you to enjoy more than 15 online streaming services, such as Spotify, Tidal, Deezer as well as thousands of web radios, but also files stored on your network. It's also an easy way to take control of your system remotely and integrate it into a multi-room ecosystem, with the choice of independent or zone-based management.
