NAD Electronics unveiled three affordable products: the D 7050 Direct Digital Network Receiver (MSRP: $999), the D 3020 Digital DAC/Amplifier (MSRP: $499) and the D 1050 USB 24/192 DAC (MSRP: $499). All three models will be July 2013.

The D 7050 Digital Network Receiver is basically an amplifier with Apple’s AirPlay Wi-Fi streaming technology integrated into it (in addition to Apple’s AirPlay, the D 7050 can also stream any UPnP audio content on a home network) – and, if no network is available, it can also stream directly from a smartphone or laptop using the latest Bluetooth. Of course, there’s a wired digital audio (no analog input, though) and a USB drive port. Digital is converted to analog (for speaker ports) via a passive two-pole reconstruction filter located right at the speaker outputs. NAD claims it’s the worlds’ first successful closed loop digital amplifier. Closed loop means that the output is compared to the input, and then compensated for any differences to achieve a ‘perfect’ output. Output is spec’d at 30-watts.

The D 3020 allows for inputs from a computer (analog) along with other digital and analog sources as well as a USB audio port. Coaxial and optical S/PDIF (digital) inputs allow for connection of anything digital (e.g., CD and DVD disc players, TV set top boxes and Apple TVs). There are also analog inputs for iPods and older non-digital audio components such as FM tuners. NAD also includes a headphone amplifier output. There’s no network port though, like the 7050 has, but it does have a Bluetooth port. It, too, is specified at 30 watts of output power.

The NAD D 1050 USB DAC is an adapter that allows you to add computer audio (via 3.5 millimeter) and HD digital audio (S/PDIF, optical and coax) to a traditional component hi-fi system. The digital inputs include S/PDIF inputs support balanced AES/EBU, coaxial and optical connectors. It also supports USB Audio Codec 2.0 allowing 192 kHz signal transmission.

All three products consume less than 0.5 watts of power in stand-by — making them a  GreenAV product.

In the press release, NAD said these products were ground-breaking, however, embedded AirPlay, USB audio inputs and network, as well as Bluetooth audio have been available on many audio products for several years.
