NAD 3120

Description

The moderately priced 3120 stereo amplifier provides state of the art performance at effective output power levels substantially greater than would be expected from the conservative rating of 25 Watts per channel.

This remarkable characteristic is made possible by a high voltage, high current output circuit that can deliver short term bursts of double or triple the rated power output in to the typical impedances of real loudspeakers.

NAD's soft clipping circuit permits listening levels beyond even these limits, by reducing harshness at high volume settings.

The audiophile version of the 3020. The ‘audiophile’ version as far as I have read is the binding post on the back and there is no tone controls. But after given this a good listen I can honestly say there is more too it than just these things that I have mention. The sound is really detailed, and the Phono stage will outperform any other. There were a number of versions of the original series 20. It came too NAD attention that many ‘audiophiles’ were buying the 3020 and use it only as a preamp which made them produce the 1020 which is basically a 3020 but without the power amp section and then they tried to up the formula which they had perfected with the 3020 and made these small changes to give it a more ‘credible’ audiophile look and they made some changes to the inside as well, cause I have both a 3020 and a 3120 and they sound different not overly much, but just enough to keep them apart, the 3120 has just a tiny bit more details and the 3020 has a more even soundstage and super smooth. This will properly be a cheaper alternative to the now more and more expensive 3020.

re: 3020/3120 manual missing page

There is a critical page missing from the NAD 3020/3120 service manual, namely, the first four steps of the output stage biasing adjustment. The procedure is almost certainly the same as for other low-power NAD output stages. If anyone has this missing page I would very much appreciate having it to complete the manual. BTW, all other downloads that I have found contain the same omission.

It is nice to have this site.
