NAD C 658 BluOS Streaming DAC/Preamplifier

Modular DAC, Preamplifier, and Streamer Offers MQA Decoding and Instant Access to Wireless High-Res Music: BluOS-Enabled NAD C 658 Also Features MM Phono Preamplifier and Headphone Amp

A triple-threat DAC, preamplifier, and BluOS streamer, NAD C 658 lets you stream high-resolution music from nearly 20 providers while offering full MQA decoding on all digital inputs and supporting two-way aptX HD Bluetooth. Its audiophile-caliber Direct Digital 35-bit/844kHz DAC ensures premium fidelity by way of a mind-boggling 130dB dynamic range, while a built-in MM phono preamplifier, dedicated high-current headphone amplifier, and Dirac Live Room Correction software make the fully modular C 658 a veritable audio decathlete equally able to serve digital and analog needs. Ditto the balanced preamplifier output, stereo subwoofer outputs, and RS-232 serial port that enhance its flexibility.

Allowing you to network stream to up to 64 zones via its role as a BluOs node, C 658 is nothing but high-resolution from input to output. All preamplifier functions are executed in digital domain, extending to the same wide-range non-truncating digital volume control used in NAD’s Masters Series components. The approach offers a very short analog signal path that uniquely remains 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 measurable limits. 

High-Resolution Streaming and Networking with BluOS Technology
C 658 boasts one of the most sophisticated high-res streaming systems available. BluOS natively supports nearly 20 streaming music services and indexing of over 250,000 tracks from local network sources. In effect, 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 and affordable to create a whole-home audio system with C 658 at its heart.

Two-Way Wireless aptX HD Bluetooth
C 658 also features two-way wireless Bluetooth capability powered by aptX HD for the highest-possible Bluetooth sound quality. You can easily stream music from smartphones, tablets, and laptops or can also use the device's integrated two-way Bluetooth feature and effortlessly stream music playing on the amp to any pair of Bluetooth-enabled headphones.

Optimize Your Listening Environment with Dirac Live Room Correction 
Dirac Live Room Correction software delivers optimized sound quality for your home-theater system. The built-in Lite version of the software, with the option to upgrade to a full-featured version for $99 USD, measures the acoustic performance of the system within the listening room and optimizes playback performance to provide transparent music reproduction. The set-up process is automated and simple, giving you the control you need to precisely tune for the best results. With Dirac Live, you can build the perfect listening environment that corrects for both the timing and colorations in sound using the supplied microphone and its powerful software.

Upgradability Via Modular Design Construction 
NAD's Modular Design Construction (MDC) means all major digital circuits on C 658 can be upgraded and replaced to keep the unit young and capable. This unique architecture keeps pace with the fast-changing world of technology. With MDC, the ability to easily upgrade a component to include future digital formats is money-saving and unprecedented. C 658 comes with two MDC slots for future expansion.
