NAD D 3020 V2 Hybrid Digital DAC Amplifier Datasheet
Outshines Other Amplifiers.
The New and Improved Digital Amplifier
The original NAD 3020 introduced a generation of music lovers to true high-fidelity sound.
The term High-Fidelity literally means “true to the original.” In the 1970’s, over a million
people rediscovered their music when they placed a NAD 3020 between their turntable
and loudspeakers. This little gem outshined amplifiers costing 10 times more with its big,
warm, detailed sound. Once people realized what they had been missing it lead them
to a lifetime of enhanced musical enjoyment. Today, the coaxial source is more likely to
be a computer or smartphone than a turntable, but the ability to choose speakers that
perfectly suit one’s taste is still a compelling argument for upgrading to a NAD amplifier.
The D 3020 starts with the original NAD 3020 concept and brings it straight into the 21st
century using the latest high-speed digital technology. Now with V2, we have refined the
looks and added a Phono input for vinyl playback.
Reinventing an Icon
By adapting to today’s media sources and using state-of-the-art digital technology for
the new world of digital music, the D 3020 puts a completely modern spin on a revered
icon. The original designer of the 3020, NAD’s Director of Advanced Technology, Bjorn
Erik Edvardsen, has been pivotal in developing the D 3020 for the new digital generation.
Offering an excellent quality 24/192 DAC with 8 channels mixed to 2 for improved resolution, the D 3020 represents the same kind of value-bending innovation that gave the
original 3020 its legendary overachieving phono stage.

Real World Performance
Stream with Bluetooth
NAD rewrote the rules for amplifiers when designing the
original 3020. Instead of letting laboratory test equipment have
the last word, we made sure that we could properly drive real
loudspeakers with real music for the real world. The D 3020
lives up to this promise through a unique implementation of
NAD PowerDrive™ developed by Edvardsen, that allows low
impedance drive (current) and high dynamic power (voltage) at
vanishingly low distortion levels. This refinement of PowerDrive
combined with a precision soft clipping circuit, lets the D 3020
sound even more powerful than it already is. An innovative
Bass EQ circuit helps small speakers sound big without
overdriving or damaging ported woofers.
The D 3020 delivers the convenience of wireless streaming with
its Bluetooth® capability. Stream all your music from a smartphone, tablet, or laptop. The D 3020 even supports the highest
audio quality Bluetooth aptX® that is becoming ever more popular for its excellent sound quality and low power consumption
compared to Wi-Fi.
More Connected
The D 3020 offers inputs for your digital and analogue sources.
Coaxial and optical inputs allow many different digital sources to
be connected, including computers, CD and DVD players, set top
boxes and media streamers like AppleTV, or satellite and cable
receivers. There are also analogue inputs including a sophisticated MM Phono input. Far from just another set of sockets,
this Phono stage includes highly accurate RIAA equalization, an
Infrasonic Warp Filter, and features both high overload margins
and extremely low noise.
Power that Truly Delivers
Power output may sound small at 30W per channel, but like all
NAD amplifiers this is very misleading, as a properly designed
30W amplifier can sound superior to a 100W amplifier from a
lesser brand. With its very small form factor, the D 3020 will
astound many for its ability to drive difficult loudspeakers to
satisfying levels without adding noise or distortion.
Mean and Green
The D 3020’s highly efficient design wastes less energy, requiring only 20% of the power needed by traditional Hi-Fi amplifiers.
It’s like trading in a gas guzzling car for a hybrid vehicle. Standby
power consumption is a miniscule <0.5W. NAD has taken
amplification to new lows, with lower distortion, lower noise,
and lower power consumption. NAD’s major focus is to find new
technology that improves musical performance while consuming less power and using fewer non-renewable resources in
