It emphasizes audiophile-grade sound, modular future-proofing, advanced room correction, and high-resolution multi-room streaming rather than packing every possible video feature. Priced around $2,999 / £2,499 at launch, it targets listeners who want strong multi-channel and stereo performance in a relatively compact, stylish package. ### Design and Build The T 778 stands out visually with a clean, modern black chassis and a large, high-resolution full-color touchscreen that dominates the front panel. The display shows album art, volume, source information, and settings, and can be dimmed or timed out during movie watching. Build quality is solid and more refined than typical mass-market AVRs, with a relatively compact footprint (approximately 435 × 140–172 × 425–430 mm) and a weight of around 12–20.5 kg depending on the exact configuration reported. Key design elements include NAD’s Modular Design Construction (MDC) slots for potential future upgrades (such as HDMI boards), high-quality speaker binding posts, and comprehensive pre-outs. Cooling is efficient thanks to the Class D amplification, though some users recommend additional ventilation in enclosed cabinets. ### Key Features and Specifications - **Amplification**: HybridDigital (Hypex UcD-based) Class D modules - 140 Wpc into 8 Ω / 170 Wpc into 4 Ω (two channels driven) - Full Disclosure Power: 9 × 85 W (all channels driven simultaneously, full bandwidth) - Dynamic power up to 165 W (8 Ω) / 280 W (4 Ω) - Damping factor > 300 - THD < 0.08 % - **Channels**: 9.2 (expandable to 7.1.4 with external amplification via pre-outs) - **Surround formats**: Dolby Atmos, DTS:X, Dolby TrueHD, DTS-HD Master Audio, and legacy formats - **Room correction**: Dirac Live (limited bandwidth version included; full-bandwidth upgrade available) - **Streaming & network**: BluOS multi-room platform (hi-res up to 24-bit/192 kHz, MQA), AirPlay 2, Spotify Connect, Tidal, Qobuz, Roon Ready, Bluetooth aptX HD, Wi-Fi, Ethernet - **Video**: 6 × HDMI 2.0b inputs, 2 × HDMI outputs (4K UHD, HDR10, Dolby Vision, HDCP 2.2, ARC/eARC on one output). Note: Original HDMI 2.0; modular design intended for later upgrades - **Other inputs**: MM phono, analog RCA, optical/coaxial digital, USB - **Outputs**: 9 speaker channels, 11.2-channel pre-outs, dual subwoofer outs, Zone 2, headphone The inclusion of a proper MM phono stage and full pre-outs makes it unusually flexible for both pure home theater and hybrid hi-fi use. ### Sound Quality The T 778 is widely praised for its sonic performance, often described as one of the more refined and “hi-fi-like” AV receivers in its class. - **Movies and multi-channel**: Dynamic, powerful, and precise. Effects are tightly localized with excellent imaging and scale. Dialogue remains clear even during intense passages. Dirac Live helps tighten bass and improve overall coherence in typical rooms. - **Stereo/music**: Particularly strong. Reviewers note a rich, detailed, and natural presentation with good midrange texture, controlled bass, and a low noise floor. It performs well enough that some users run it as a primary stereo amplifier without feeling the need for a separate power amp. - **Overall character**: Neutral to slightly warm and full-bodied, with strong dynamics and refinement rather than a bright or overly clinical edge. The HybridDigital amplification contributes to clean power delivery and good speaker control. It is frequently compared favorably to more expensive processors or separates for overall musicality and engagement. ### Pros - Excellent sound quality for both movies and music - Strong real-world power and high damping factor - Dirac Live room correction - Comprehensive BluOS high-resolution multi-room streaming - Large, useful touchscreen interface - Modular Design Construction for potential future upgrades - Full pre-outs and MM phono input - Compact and stylish relative to many flagship AVRs ### Cons - Original HDMI 2.0 (not native 2.1); relies on modular upgrades that have been limited or slow to appear - Some users report occasional operational quirks (pops on source changes, software quirks) - Long-term reliability concerns raised by a minority of owners (heat-related or module issues) - Dirac Live included version is bandwidth-limited (full version is a paid upgrade) - Premium pricing ### Verdict The NAD T 778 is a refined, music-first AV receiver that prioritizes sound quality, streaming flexibility, and modular design over packing the absolute latest video connectivity. Its HybridDigital amplification, Dirac Live, and BluOS platform deliver a compelling combination of dynamic multi-channel performance and genuine hi-fi stereo capability. It is an excellent choice for listeners who value sonic refinement and multi-room music as much as (or more than) the newest gaming/HDMI 2.1 features. While the lack of native HDMI 2.1 and occasional software/hardware reports are drawbacks, the core audio performance remains a standout in its price range. For those seeking a stylish, capable, and musically engaging flagship-level AVR, the T 778 continues to earn strong recommendations. The NAD T778 is a high-performance 9.2-channel AV surround sound receiver featuring NAD's Hybrid Digital amplifier technology.
