PROS / It has a two-zone feature for expanded audio.
CONS / It lacks wireless connectivity.
VERDICT / The NAD T 748 v2 is the only AV receiver in our comparative review that doesn’t have Wi-Fi or Bluetooth, but it’s very easy to use and has good output power.
The NAD T 748 v2 is a home theater receiver with good power output and the necessary audio decoders for excellent surround sound, but few features beyond that. It lacks the connectivity of the best AV receivers, but this is an old-school receiver that prioritizes sound quality over function. As with every AV receiver, you can watch all your favorite high-definition DVDs and Blu-rays through it with Dolby TrueHD and DTS-HD audio formats for a great theater experience, but it lacks other audio decoders.
The NAD T 748 v2 is compatible with 3D and 4K video, which is important, because you should be able to use an AV receiver as a central hub for all your input sources. However, the NAD T only has four HDMI inputs. Most receivers have six. It's one of the few receivers at this price point that doesn't offer wireless connectivity for Wi-Fi and Bluetooth. You need to make sure that four HDMI inputs is sufficient for your needs before you purchase this receiver. However, it has three optical inputs, which may offset the disadvantages of having only four HDMI inputs.
The power output of the NAD T 748 v2 is what makes it one of the top 10 AV receivers for around $500. With 6-ohm speakers, it has an output of 120 watts per channel, which is excellent. It features seven channels and a subwoofer pre-out. This means it can power front left, front right, front center, middle right, middle left, back right and back left speakers. It also features two-zone audio, which means you can split two of the speakers from the main channels and create a second zone of audio from a second source. For example, you can use two channels for your home theater and two channels for speakers in a different room.
This receiver has a signal-to-noise ratio of 100 dB, which means you get an exceptionally clean audio signal. It also has a total harmonic distortion of just .08 percent, so the output signal is almost identical to the input. These metrics tell part of the story, but there is also a subjective quality to audio equipment, and NAD has a reputation for building exceptional amplifiers. If you’re planning on using your receiver to play music for house parties, this is a great choice.
The T 748 v2 has an exceptionally simple user interface that will feel familiar to people who have used older audio equipment. Unlike some competing companies, NAD does not have a smartphone app that can control the receiver. However, the receiver does come with a remote that makes hands-free operation relatively simple.
The NAD T 748 v2 emphasizes audio performance over everything else, which makes this one of the best home theater receivers if you plan on listening to a lot of music through it. However, it lacks wireless connectivity, which is practically ubiquitous among AV receivers at this price.
