Product Overview:

Surround yourself with perfection. The T 778 represents NAD’s unwavering philosophy of real-world performance, simplicity of operation, and future upgradability. Only NAD offers Modular Design Construction (MDC), our proven method for preventing premature obsolescence. Dolby® Atmos™ and DTS® Master Audio combine with Dirac Live™ room correction to deliver hyper-realism that captures every dimension of a performance. Add bit-perfect UHD 4K 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 and nine channels of high current amplification capable of powering any loudspeaker to its maximum potential. The T 778 is secondto-none in terms of flexibility and up-to-the-minute digital technology.

With MDC all major digital circuits can be upgraded and replaced to keep the T 778 forever young and capable. This NAD innovation is a unique architecture that keeps pace with the fast-changing world of digital formats by allowing connectivity and feature upgrades as new technology becomes available. MDC defies premature obsolescence, so you can keep pace with the latest developments in high performance AV through dealer-installed modules. Your T 778 can be upgraded as your needs and tastes develop, and you only need to replace the module you want to upgrade, not the entire AV Amplifier.

The T 778 carries on the enviable task of representing NAD’s finest surround sound performance. It offers full HDMI video switching and surround sound decoding to 7.2.4 channels. Brimming with a full array of sophisticated features like the high resolution lossless surround formats from Dolby TrueHD and DTS Master Audio decoding, and now object-based audio with Dolby Atmos, the T 778 provides the highest levels of performance. The surround mode of the source material is automatically detected via the digital inputs of the T 778, and the most advanced form of decoding, based on your setup, is switched in. Conversion of the encoded digital bitstream is performed with high resolution and extremely linear D/A converters carefully selected for their performance capabilities.
