The 3020 (and 3055) succeeded partly due to NAD's virtual corporation approach a decade before virtual corps were the rage. The sound was magic because Bjorn Evard Evardsen in NAD's London design office combined Tom Holman's (think THX) elegant and simple preamp design with his smart poweramp circuits and had Proton (Fulet of Taiwan) mass build it at a low cost. Proton was a majority owner of NAD and therefore kept costs low. NAD was able to popularize the 'champagne sound on a beer budget' approach due to their unique formula. Today many, many audio companies follow in their wake. Yet NAD certainly did get a lot of the elements right in a big way, first. As mentioned elsewhere, if you like the 3020, you should have heard the Naim Nait, the Creek 4040 or the A&R A60 (now Arcam) - these UK 3020s showed how much ahead the Brits and Scots were in affordable audio as far back as the 60's. I'd say that Walter Woods is more akin to champagne on a champagne budget, however. In the audiophile world, there are no shortage of those type of esoteric US companies! Tom?!!
