Crutchfield: NAD D 7050 Digital Network Amplifier
Our take on the NAD D 7050 by Crutchfield's David Brown
Modern features, classic sound
NAD has been designing great-sounding audio gear for decades. Their integrated amplifiers have long been favorites in the audiophile community as well as with our customers. Now, they've combined their old-school sound with the modern convenience of digital music in their D 7050 Direct Digital Network Amplifier. With built-in Wi-Fi, a host of digital source options, and robust amplification, this amp can bring all your music together to make your speakers sing with classic NAD sound.
When it comes to music listening, nothing beats the convenience of wireless streaming — as long as you don't have to jump through too many hoops to get there. That's why the D 7050 offers lots of ways to get the music playing easily and quickly. Built-in Wi-Fi lets you get connected to your wireless home network without running an Ethernet cable from your router. But if a wired connection suits your needs, there's an Ethernet port on the rear panel, too.
AirPlay and Bluetooth on board
The D 7050 features built-in Apple AirPlay, so you can stream music from your iPhone® or iPad®, including from apps like Spotify® and YouTube™. If you have a networked computer running iTunes®, you can also use AirPlay to send music from your music library to the D 7050 for playback. If your iPhone or iPad is connected to the same network as your computer, than use the Apple Remote app to control iTunes playback. Even without AirPlay or Wi-Fi, you can enjoy instant wireless music streaming over Bluetooth from any compatible smartphone, tablet, or computer.
The compact D 7050 can rest vertically or horizontally, so it can fit in just about any room. The source and volume display even reorients itself automatically.
24-bit/96kHz asynchronous USB input
Not interested in wireless streaming? You can still use your computer as a music source by connecting it to the D 7050's asynchronous USB input. This connection improves your computer's sound and is capable of playing high-resolution music files for sound quality that even trumps CDs. There are also optical and coaxial digital inputs that feed this amp's high-quality digital-to-analog converter (DAC) for sound that's silky smooth.
NAD's innovative direct digital technology
NAD first introduced "direct digital" technology on their highly acclaimed M2 integrated amplifier. By eliminating analog signal paths between the digital converter and the output stage, NAD prevents these noisy circuits from introducing distortion that degrades sound quality. So your music remains as pure as possible from the source all the way to your speakers. Plus, NAD's innovative "closed-loop" design compares the input signal with the output signal, compensating for any differences before sending it out to your speakers. It's a highly efficient design, allowing for a compact enclosure you can stand vertically on a bookshelf or desk or place horizontally in a component rack or cabinet.
Free app for Wi-Fi control with your smartphone
You won't find a lot of unnecessary buttons cluttering the streamlined D 7050. There's an extra-large volume knob and a smaller dial for selecting your music source. But if you download the free NAD D 7050 app for Apple® or Android™, you can control the player's functions with your smartphone. In addition to volume control and source selection, you can select the crossover point for your powered subwoofer, for smooth integration with your speakers. Plus, if you own PSB Imagine Mini or Imagine T speakers, the app's PerfectPitch™ uses the amp's sophisticated digital processing and EQ to deliver an unparalleled level of synergy for incredibly accurate playback.

Plugged it in and attached it my router. That all worked great. But the remote has to be the worst remote I have ever seen. The fuzzy coating is going to clot. The battery compartment opens with a bent paper clip and the finesse of a locksmith. Way to cleaver.

Direct Digital Amplifier: Direct Digital means there are no noise and distortion producing analog circuits in the D 7050; your music remains digital right up to the speaker outputs. NAD's Direct Digital technology of the D 7050 performs all preamplifier functions in the digital domain using sophisticated software to control all aspects of performance. Digital is converted to analog by a simple passive two-pole reconstruction filter located right at the speaker outputs; then compares the output to the input, and compensates for any differences to achieve the perfect result. The high efficiency of NAD's Direct Digital amplifier technology significantly reduces the size of the heat sinks and power supply, which are physically large in high performance analog amplifiers, while offering improved sound quality.
- LSI's + Multi-Layer PCB's: The NAD 7050 direct digital amplifier employs large scale integrated circuits (LSI) and multi-layer printed circuit boards (PCB) to optimize speed and performance.
- NAD's Full Disclosure Power Ratings: NAD uses Full Disclosure Power (FDP), the most demanding criterion for performance measurement. FDP specifies distortion under the most extreme conditions of low impedance loads and frequency extremes, rather than the simple and easy 1kHz @ 8 ohms test quoted by many of other manufactures. NAD uses this stricter performance criterion because it more closely matches the demands of real music and real loudspeakers. Maintaining specified distortion at 4 ohms and at 20Hz to 20kHz is a much more difficult achievement. The NAD D 7050 is rated at 50 watts x 2 channel (@ 20-20kHz, in 4-ohms, with 0.004% THD).
Binding Post Speaker Terminals: The NAD D 7050 hybrid digital amplifier is equipped with four binding post terminals to connect your loudspeakers. The binding post speaker terminals will accept bare wire (up to 10AWG), banana plugs (single only), pin-connectors, and spade-connectors.
Analog Audio Outputs: The NAD D 7050 offers stereo RCA outputs that can act as a pre-out to send an audio signal to a separate amplifier, or a subwoofer output to send a low-pass audio signal (up to 200Hz) to a powered subwoofer.
Built-in Headphone Amp: The D 7050 features an integrated headphone amp with a 3.5mm headphone output jack to connect a pair of headphones for private listening. A specially designed low noise headphone circuitry accommodates a wide range of headphones, even 600-ohm studio models. Once headphones are connected to the D 7050, your connected speakers will be turned off.
Perfect Pitch: The PerfectPitch software program is available as a free firmware upgrade for all D 7050 owners and can be downloaded here. Once installed, it is selected or bypassed using the D 7050 Remote App available free at the Apple App Store. PerfectPitch utilizes carefully developed DSP filters to raise accuracy to a new height of perfection for PSB speakers. With PerfectPitch engaged on the NAD D 7050, your PSB speakers sound smoother and more detailed in the midrange with enhanced bass extension. The midrange is less forward and more three-dimensional with superior depth and width. This creates a spacious and airy sound field with improved image focus.
Wired or Wireless Network Connection: The NAD D 7050 is equipped with dual network connection methods. There's an RJ-45 LAN (Ethernet) port for direct wired connection to your home network, and there's also the built-in Wi-Fi feature that includes Wi-Fi Protected Setup for safe and secure connection to your wireless home network.
