Details Review


The NAD T 778 boasts a sleek and minimalist design that blends seamlessly with various home decor styles. Its well-organized front panel, featuring a large display, user-friendly buttons, and a volume knob, offers a sense of simplicity and sophistication. The overall build quality is solid, and it feels like a premium piece of equipment.

Some users may find the unit's size and weight a bit unwieldy, making installation and setup a bit challenging. The remote control, while functional, lacks a bit of the premium feel you might expect from a device in this price range.


Connectivity is one of the standout features of the NAD T 778 A/V Receiver. It provides users with a diverse range of inputs and outputs to cater to a variety of audio and video sources. HDMI, analog, digital – you name it, and this receiver probably has it covered. Vinyl enthusiasts will particularly appreciate the dedicated phono input, allowing them to relish the warmth and nostalgia of their record collections.

One notable feature that sets the NAD T 778 apart is its eARC support. This means it's equipped to handle the latest audio and video formats, ensuring that your home theater system stays relevant and future-proof. The inclusion of balanced XLR inputs is another feather in its cap, offering superior audio quality for users with components that can take advantage of this feature.

While the device's connectivity options are impressive, it's worth noting that a small subset of users has encountered occasional hiccups. HDMI handshake problems and glitches during input switching have been reported, albeit infrequently. These issues can be vexing, especially when you're trying to enjoy a seamless entertainment experience. However, it's important to remember that these problems don't seem to be widespread, and for many users, the connectivity of the NAD T 778 is a major selling point.


Now, let's talk about performance—the heart of any audio-video receiver. The NAD T 778 truly shines in this department. It's like having a powerhouse at the center of your home theater. The audio quality is exceptional, delivering clear, detailed sound that resonates with lifelike precision.

One of its strengths is its robust amplifier, capable of filling even large rooms with immersive sound. Whether you're watching a blockbuster movie, listening to your favorite album, or gaming, the NAD T 778 ensures that every sound is conveyed with power and finesse. For home theater enthusiasts, this receiver excels in creating a three-dimensional audio experience that engulfs you in the action on the screen.

What elevates the audio quality even further is the inclusion of Dirac Live Room Correction. This feature tailors the audio output to the specific acoustic characteristics of your room, resulting in a listening experience that's finely tuned to your space. It's a game-changer for audiophiles who want their audio to be as precise and balanced as possible.

Of course, no product is without its downsides. Some users have noted that the NAD T 778 can get warm during extended use. While this isn't uncommon for A/V receivers, it's something to be aware of, especially if you plan on pushing the system to its limits during long movie marathons or extended gaming sessions.

Another aspect to consider is the setup and calibration process. While it ultimately delivers great results, it can be somewhat complex and time-consuming for those who aren't well-versed in audio equipment. If you're a tech-savvy enthusiast, you might relish the customization and fine-tuning options, but for beginners, it could be a bit overwhelming.

Where and When to Use

The NAD T 778 is versatile, making it suitable for a wide range of applications. It's an excellent choice for home theaters, providing an immersive experience for movie nights. Music enthusiasts will also appreciate its capabilities, as it can handle both stereo and multi-channel music with finesse. The device's flexibility allows it to be used in various room sizes, from small to large, making it adaptable to different home setups.

The device's size and weight may make it less suitable for smaller rooms or setups where space is limited. Additionally, it might be considered overkill for users who have less demanding audio and video needs.

Compatible Devices

The NAD T 778 is compatible with a wide range of devices, making it a central hub for your home entertainment system. It plays nicely with 4K TVs, gaming consoles, Blu-ray players, and streaming devices. Its support for various audio codecs and formats ensures that it can handle virtually any source you throw at it. Users appreciate the inclusion of Bluetooth and Wi-Fi, which expand the device's connectivity options even further.

Some users have reported occasional compatibility issues with certain devices, particularly when it comes to HDMI connections. This can be frustrating, especially when you expect seamless integration with your existing equipment.

Ease of Use

The NAD T 778, despite its advanced features, manages to offer a user-friendly experience. The on-screen setup wizard guides users through the initial configuration, and the well-organized menu system simplifies tweaking settings. The inclusion of a mobile app for remote control and adjustments adds to the convenience.

While the device is generally user-friendly, some users have found the setup process a bit complicated, especially when it comes to advanced features like Dirac Live room correction. The remote control, as mentioned earlier, is functional but may not meet the expectations of users who prefer a more premium feel.


Considering its feature set and performance, the NAD T 778 is often seen as a good value for those who seek high-end audio and video experiences. It's priced competitively in its category and can be a cost-effective solution for those looking to build or upgrade their home entertainment system.

The cost of the NAD T 778 might be a barrier for budget-conscious consumers, especially when factoring in the additional expense of quality speakers and source components to complement it. The device's pricing may put it out of reach for some potential buyers.
