NAD C 658 BluOS Streaming DAC

Redefining the Architecture of Hi-Fi Playback

The C 658 creates 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. An optional HDMI 4k switcher module is available now allowing the best sound from any of the many HDMI sources available (like game consoles and video STBs). While the C 658 immediately replaces (or adds) your Streamer, DAC, and Preamp, it also adds many new features you may not be aware of, like a Bluetooth aptX HD transmitter to use with your wireless headphones. The highly flexible outputs allow for a true balanced connection to powered speakers or amplifiers. Single-ended connections for amplifiers and subwoofers are also provided and include an adjustable subwoofer crossover executed perfectly in the digital domain. A highly sophisticated MM Phono input is also included along with line inputs for legacy analog components.

BluOS™ Enabled

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 desk top 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 our Classic Series of components which have an enviable reputation for giving Music Lovers more enjoyment for less money. If you want a solid block of hand–crafted aluminum with gold plated accents you’ll need to look elsewhere. If you want state-of-the-art performance and features in a sturdy no-nonsense package then you have the right address.

High Resolution in Every Detail

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 our Masters Series components. This offers an incredibly short analog signal path that, rather uniquely, is identical for all volume settings.

Make the Speakers Disappear (It’s Not Magic)

The C 658 is also 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 your speakers, in addition to the frequency response of your room, for a truly transparent window into the musical performance.

Master Quality Authenticated

Master Quality Authenticated (MQA) is a revolutionary end-to-end technology built into every BluOS Enabled amplifier to capture and deliver MQA music to your speakers in the purest quality. All BluOS Enabled players and systems include a powerful decoder and audio renderer for the millions of the MQA encoded songs, The MQA logo shown in the BluOS app indicates that the unit is decoding and playing an MQA stream or file, and lets you know that you are hearing exactly what the artist recorded and approved in the studio.

NAD C 298 Stereo Power Amplifier

Redefining the State of the Art with Purifi Technology

NAD has introduced some of the most innovative amplifier technology in its nearly 50 year history, starting with the 3020 on through such cutting edge models as the 2200, the 208, and the M2. Now we are making the amazing new Eigentakt™ (self-clocking) technology, recently introduced to the world in the EISA Award winning Masters M33, available to a wider audience with the very affordable C 298. We are thrilled to provide this unprecedented level of performance. In short, a perfect companion for the C 658 BluOS Streaming DAC preamplifier.

Amazing Flexibility

The NAD C 298 may appear to be a basic Power Amplifier, but we have carefully thought through all the use cases typically encountered to create a rich feature content. Selectable balanced inputs make the C 298 a natural for studio use or connection to High End Preamplifiers and Processors. These inputs include a trim control useful for matching to other components. A line out allows further addition of power on the same channel for additional speakers or subwoofers. Auto-sense with selectable threshold is perfect for automating complex systems or hiding the amplifier out of sight in a cabinet. We even include a Ground Lug that can be very useful for eliminating ground loops and noise in complex multi-unit systems. Added to all this connectivity is a Bridge Switch that turns the C 298 into an amazingly powerful Monobloc Amplifier. Start with one and add a second C 298 later when you upgrade your speakers.

Getting the Basics Right

It is surprising how many seemingly advanced products in the market today often miss many of the most basic requirements for satisfying performance. Low noise circuits, accurate channel balance, proper input and output impedance characteristics, high overload margins and stability with difficult speaker loads. NAD C 298 starts by getting these things precisely right and advances from there. Our line inputs, both Balanced and Single-ended, can accommodate all kinds of analog source components by offering ideal input impedance characteristics with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation caused by inappropriate loading of the source device. These are all details you can hear.

Sophisticated Power

NAD C 298 has moved away from the old fashioned and very power hungry linear power supplies and Class AB output stages that waste nearly half of the energy consumed producing heat rather than sound. Instead we have developed even better performing circuits based on switch mode power supplies and Class D output stages. Once thought to be inferior to traditional topologies, NAD’s advanced work in this area has created some of the best performing amplifiers regardless of basic design principle. These new designs are very linear over a wide bandwidth and provide consistent performance into all speaker loads, providing a dramatic advance over previous models.

The generously dimensioned power supply easily allows for 185 watts continuous and over 570 watts instantaneous power for short term musical transients. Innovative Asymmetrical Power-Drive fully utilizes every last watt available with its vast reserves of dynamic power available to accurately reproduce musical transients without distortion or compression. It can operate with any AC mains voltage from 100V to 240V and provides pure DC power to all the various stages of the NAD C 298. This highly efficient supply also provides near perfect regulation of voltage across a wide range of conditions and provides a solid noise-free foundation for the amplifying stages.

Purifi ‘Eigentakt’ Amplifier Technology

Purifi is a Danish technology company that has brought together several of the industry’s leading engineers to apply advanced mathematical modelling to solve the last remaining limitations of audio amplifiers. While there are many good sounding amplifiers on the market today, Purifi has taken a fresh look at every aspect of amplifier performance and found many seemingly small non-linearities that can make a dramatic difference in the overall sound. This return to first principles has resulted in a stunningly simple approach to some remarkably complex problems. With features and technology unmatched by other amplifiers in its class, the C 298 amplifier is an easy upgrade for any system and a surprising partner for the most sophisticated and advanced loudspeakers on the market. The Eigentakt modules are manufactured by NAD under license from Purifi, allowing NAD to optimize these specifically in combination with the custom designed power supply and input stages of the NAD C 298.

Klipsch La Scala III Floorstanding Speaker – Black – Pair

The Klipsch La Scala III delivers the same sparkling highs, extreme output and unsurpassed low distortion bass response as the original design. It also continues to utilize the same horn-loaded drivers as the Klipschorn, making it highly efficient and able to produce high volumes with undetectable distortion.

An updated classic

Have a big room? Need a big speaker to fill it? Then the Klipsch Heritage Series La Scala II should definitely be on your short list. Originally released in 1963 for use as a “portable” public address speaker, it also turned out to be a fantastic performer for the home. Now built from resonance-absorbing 1-inch thick MDF instead of plywood and aesthetically enhanced for living room environments, the latest version of this classic horn-loaded floor-standing speaker is ready to rock your world with stunning dynamics, low-distortion bass, and extreme output levels.

A fully horn-loaded design

The Klipsch La Scala III horn-loaded tweeter and midrange compression drivers give it exceptional sensitivity, flat frequency response, and broad, controlled dispersion. This translates to unequaled clarity, detail, and lightning-quick transients for that “live, you-are-there” Klipsch sound. A 15″ folded-horn woofer delivers truly astonishing bass performance and responsiveness. The La Scala II’s extremely high sensitivity also makes it a great choice for low- and medium-powered tube amps. The two-piece design, with separate tweeter/midrange and bass cabinets, helps make transporting and positioning the speaker easier.

A hand-built beauty

This speaker looks every bit as good as it sounds, featuring a handsome, furniture-grade woodgrain veneer cabinet. Klipsch still makes the La Scala II one at a time by hand in Hope, Arkansas. Each speaker is available in a beautiful Cherry, Walnut, or Black Ash lacquered wood veneer finish.
