NAD C 510 Direct Digital Preamp DAC

A preamp for the digital age

For decades, audiophiles have organized their systems with a source component, such as a CD player, along with a preamplifier and a power amplifier driving a pair of speakers. However, times have changed and today many music lovers have replaced their physical media with digital music files. It is for this purpose that the C 510 DirectDigital™ Preamp/DAC was created.

Harnessing the power of DirectDigital, the C 510 accentuates all music tracks, delivering a gripping and engaging musical experience when combined with your favourite power amplifier. As a member of the NAD preamp family, the C 510 is a reliable, innovative product for digital audio systems everywhere.

35-bit Direct Digital Preamp DAC

The C 510 Direct Digital™ Preamp/DAC promises to redefine hi-fi separates. For decades, audiophiles have organized their systems with a source component, such as a CD player, along with a preamplifier and a power amplifier driving a pair of speakers. This has recently changed and today, the CD player might be replaced by a computer or dedicated music streamer connected to the Internet or local Network Attached Storage. The best of these are capable of streaming high-res 24-bit studio master recordings, which are now readily available. Thanks to the incredible convenience and stunning sound quality of computer audio, many music lovers have completely replaced all physical media with digital music files. It is for this purpose that the C 510 Direct Digital Preamp/DAC was created.

Well Connected

The C 510 includes connectivity for a wide variety of digital sources including an Asynchronous USB Type B port for direct connection to your PC or Mac. Meaning that the C 510 provides the precision clock for the USB data rather than the imprecise clock in the computer, plus it supports sampling rates of up to 24-bit/192kHz. Two HDMI inputs with a video pass through provide a secure encrypted path for High Res Audio, and allow the C 510 to perform a role as a video switcher. The 2-channel PCM audio track that is present on all video programming is stripped from the HDMI input with the video passing untouched to a connected video display. We have also included 3 SPDIF inputs— all 24/192 capable—in Optical, Coaxial and AES/EBU formats.

No Noise, No Distortion

Unlike a traditional analogue preamplifier, the C 510 Direct Digital Preamp/DAC does not produce any noise or distortion that can obscure detail and limit the performance of many systems. By performing preamp functions like volume and source selection in the digital domain, the C 510 shortens the signal path and opens up new system possibilities. Whether driving your favourite power amplifier or feeding active loudspeakers, the C 510 has the requisite drive and finesse to get the best possible performance.

Thoughtful, Simple Design

The analogue output operates in true balanced mode driven by a Class A biased operational amplifier. Both Balanced XLR and single-ended outputs are provided to get the best performance with any amplifier. As with all NAD products, we have taken special care designing the power supply and critical circuit layout to optimize the performance of the premium parts used extensively throughout the C 510. A 12V trigger and RS-232 port allow for system automation interface. Selected input and incoming sample rate are displayed on the front panel display.

NAD Direct Digital™ Innovation

Built using the incredible processing power and precision of our own Direct Digital™ architecture, the C 510 ushers in a new era of affordability for state-of-the-art performance. The C 510’s dynamic range betters other DACs and preamplifiers by about 20dB. That is a thousand times more accurate! You can hear it in both the precision micro-dynamics and the dead silence of this remarkable device. As the volume level is controlled by mathematics in the digital domain, there is no mechanical or electrical imprecision. Of course, this requires very high resolution, which is provided by the 35-bit architecture of the C 510; even 24-bit files are not truncated until well below the threshold of audibility.

All Digital, All Day Long

As a pure digital device, analogue inputs have not been included. This purity of design and singleness of purpose is in the very best tradition of high-end audio. Like all NAD products, the C 510 Direct Digital™ Preamp/DAC offers exceptional value and a remarkable level of performance. The C 510 is the perfect centrepiece to a cutting edge high-resolution digital audio system.
