To be honest I wouldn't agree with NAD as a reliable brand anymore. At one time NAD made some very nice, solid and sweet sounding gear which sold for sensible prices (I always thought they had a lot in common with Rotel in that regard).Although their gear still seems to perform pretty well they don't seem to have a great reputation for reliability anymore. The new generation 3020 was quite a neat idea but it didn't seem to be particularly well executed.
But when I look around they are still very good.
But you could be right.
