NAD T778

Reference level AV amplifier

AV Plus 3/2021 test summary:

"A bright future ahead

NAD T778 is an excellent device not only in terms of usability but also in terms of sound quality, which is almost completely future-proof thanks to its upgradeable MDC modules. At the moment, it doesn't necessarily hurt that its hdmi connection is "only" model 2.0b, but if the amplifier will be in your equipment shelf for the same time as the projector's lamp lasts, you can prepare for a small upgrade at some point.

Looking at today's tip, however, the T778 is a sure choice in its category and, in our opinion, the real king of its price range!"

BluOS Enabled 4K Ultra HD Receiver with Immersive Sound

NAD's reference Audio Video Receiver (AVR) is a cutting-edge Powerhouse for state of the art music and home theater. Well known for our high value/ high performance Reputation in the AVR category, the brand's reference model builds on that Legacy with an expansion of unwavering Philosophy of real-world performance, simplicity of operation, and future upgradeability.

Efficient Distortion-free Amplification

The T 778 features the latest developments in NAD's Hybrid Digital technology to create 9 high current/high power channels of amplification with improved efficiency. Designed with NAD's full disclosure approach to power ratings, the NAD AVR conservatively delivers 80W FDP and 9 x 160W FTC, all channels driven at rated distortion. For flexibility, the amp channels are configurable to be used for surround or second zone audio. The silent black background and explosive dynamics afforded by this amplifier technology adds lifelike realism, drama and excitement to all your music and movies.

Fully Featured Surround

The T 778 is second-to-none in terms of flexibility and up-to-the-minute digital technology. Only NAD offers Modular Design Construction (MDC), the company's proven method for preventing premature obsolescence. 7.1.4 Dolby® Atmos™, DTS® Master Audio combine with Dirac Live™ room correction to deliver hyper-realism that captures every dimension of a performance. Add bit-perfect 4K UHD video pass-through and the T 778 delivers the most accurate sound and image experience you've ever had. Musical performance is outstanding with High Res Multi-room streaming via BluOS.

Complete and Compact

As with all NAD components, the company's latest offering continues their 'simple is better' design philosophy. This Sensible approach contributes to ease of use and maximizes performance where it counts. A perfect example is the striking new touch screen and ergonomic refinements that simplify operation and ease of access.
