The Absolute Sound

Getting it Right

We never overlook the most crucial of requirements. From low noise circuits to precise volume control action, to accurate channel balance and proper input and output impedance characteristics, we here at NAD do everything we can to get these things exactly right. We also include an MM Phono stage with precisely accurate RIAA equalization, high overload margins, extremely low noise, and an innovative circuit to suppress infrasonic noise that is present on all LPs – all without affecting bass response. Our line inputs can accommodate all kinds of analogue source components by offering ideal input impedance characteristics with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation. We include a separate headphone amplifier with low output impedance and very high output voltage capability – enough to drive even high impedance studio monitor headphones. Low impedance line outputs that can connect to subwoofers extend the versatility of this well thought out amplifier.

Forward Thinking

Modular Design Construction (MDC), allows you to customise your NAD amplifier with additional capabilities and features, now or in the future. The two available MDC slots can accommodate a variety of upgrade modules including 4K video capable HDMI switching, additional Digital Inputs, additional Analogue and Phono Inputs, and one of the most advanced Hi-Res Audio multi-room wireless systems available, the BluOS music management system developed by Bluesound. BluOS connects to your network and is controlled via smartphone, tablet or desktop to manage your music collection and connect you to a growing list of high-quality streaming music services.

Instant Connection

You can connect instantly to the C 368 with Bluetooth® aptX®, allowing you to stream music wirelessly from any Bluetooth-enabled device. Bluetooth can also be used to listen to other sources connected to the C 368 via wireless headphones. There is also a control app to control all functions of your C 368. Adding the optional BluOS Module provides access to your local area network via Wi-Fi or wired Ethernet connection and adds Hi-Res Audio streaming. The BluOS Module also makes the C 368 a single-zone streamer in a complete multi-room wireless music system that is fully compatible with BluOS Enabled music systems and wireless speakers.

Sophisticated Power

In the last few years, NAD has moved away from the old-fashioned linear power supplies and Class AB output stages that waste energy, and have instead 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.

Furthermore, the power supply is capable of 80 watts continuously and over 120 watts instantaneously to allow for short-term musical transients. It can operate with any AC mains voltage from 100 to 240 volts and provides pure DC power to all the various stages of the C 368. 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.

The C 368 uses a customized version of the proven Hypex UcD output stage. This allows for massive power with nearly unmeasurable distortion and noise in the audible range. Every detail of this design has been carefully planned and perfectly executed to produce every last drop of performance.

It sounds delightful—lots of power, deep, punchy bass, smooth midrange and highs. It showed none of the solid-state anomalies that have historically made transistors in general and Class D in particular sound unpleasant. Easy to set up, easy to use, extremely flexible when used with Bluesound gear, this could be the last hi-fi purchase you’ll need to make. I was impressed, which seldom happens. Strongly recommended.

The presentation has an unmistakeable fullness, but never feels choked because of it – or tonally imbalanced for that matter. The layered instrumentation has room to breathe in the NAD’s wide-open and scrupulous soundstage, and drips through with marked intent and plenty of detail to communicate the band’s spooky sonic persona.

One of the most fluid and refined sounding amplifiers I've tested in quite a while. This is a seriously clever modern amplifier and as such, one that comes recommended.
