NAD 3020


The NAD 3020 can be used as the heart of an elaborate audiophile sound system.

For example, the pre-amp out jacks may be connected via a stereo patch cord to any high quality separate power amplifier.

To use a separate high power amplifier for your main stereo speakers while continuing to use the nad 3020'S inbuilt power amp for headphones or extension speakers, simply install Y adaptors to split the signal from the pre-amp out jacks.

The pre-amp stage is capable of driving several power amplifiers in parallel, or the long signal cables required to connect to power amplifiers located near the speakers, or to powered speakers.

The best sound money can buy

Submitted by almarg4748

Punchy and accurate sound. Immensely reliable; mine is nearly 40 years old and feeding equally old KLH speakers, I haven't heard a better system since! Because of it's discrete power stages and toroidial transformers it has instantaneous response to dramatic music whilst staying crystal clear. Despite being designed for vinyl it is far more powerful than you would expect even being forced to contend with the massive increase of headroom required by modern day CDs. Can drive separate amps as a pre-amp as well and has tape/tuner/disc/aux inputs and a wire wound volume control. All in all a little miracle despite being a blast from the past.

Excellent amp. I got one 2 months ago and works flashless. My Rega RP1 sounds better that if I connected to a Rotel 1095 amp and 968 rotel pre- amp. If you have any chance of get one don't doubt it. My is not modified, but my friend just sent one to modification, now I am waiting to see any improvement and compare apples to apples.

This isn't a bad amp but I think it is a bit overrated. It was very great value for the money when it arrived, but in my opinion it's not brilliant that some might want to acclaim. For some reason this amp has a nostalgic aura around it which - I think - blurres the ability to be objective. My 3020 B did a good job with bookshelf speakers but was a bit harsch in the treble region. For me it was an average amp.



re: NAD 3020

My amp has started to give quite a strong hum, initially, in the loudspeakers, when I turn it on. It fades away within three-four seconds, but is a bad sign. I believe this comes from electrolytic condensers, being more and more dried out. Maybe this is an odd problem, but it may also show that all units have - after all - a limited life span.
If anyone had the same problem, please reply to this message. Regards.

re: 3020

I first heard this amp at a friends house in 1984. I was very jealous and even at the reasonable preice of this amp , I could not afford to buy it as a student. many years have passed and I my interest in vinyl and the purest dounds has ben re-ignited . I managed to buy one second hand . It has an aux button mission and will need aservice but it sounds magnificently sweet. I have heard many systems and amps since i first heard this amp and nothing comes close if you like a musically definative but sweet and mellow sounding piece of kit.

Which version?


I am looking to get one of these amps. Is there a definitive version? I'm not sure of the differences between them.


Buttons for 3020

Does anybody know of a source of the buttons for a 3020? I'm missing one (the power switch).

Buttons for 3020

Hope you found what you were looking for. I'm missing Bass button. Any ideas? Thanks.

different model

The 3020i I own is slightly different to the 3020 shown.
3020i has no power meter and no DIN socket.
Does anyone know if the circuit is the same?

NAD 3020

The bias adjust instructions (and associated circuits) are certainly completely different.
Anyway, all the information you need for the 3020i appears to be in the manual.
Good luck

Oops! I hadn't downloaded the service manual so didn't notice that it included this model. The only problem with mine is the worn out switches.
Thanks for the tip.
